It\u2019s how your users begin interacting with you\u2014think logging in on your Facebook account or Outlook email account.&nbsp;<\/p>\n\n\n\n<p>However, despite being such a familiar step in this digital age, a login page is often overlooked for thorough testing. A single broken flow or security loophole in the login process can disrupt user access, resulting in poor first impressions or data breaches.<\/p>\n\n\n\n<p>The login page is where trust begins, from personalized dashboards to confidential information. That\u2019s why writing robust test cases for them is an absolute necessity for testing efforts.<\/p>\n\n\n\n<p>In this blog, we\u2019ll walk through the different types of test cases for login pages you should know about whether you\u2019re testing a mobile app, website, or a multi-platform system. We\u2019ll also explore the best practices for writing these test cases. But first, a quick refresher on the basics:<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Characteristics and Components of a Login Page<\/strong><\/h2>\n\n\n\n<p>Even though designs vary across apps, from Gmail to mobile banking sites, the core elements of login pages remain consistent. Here are the most common components:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Username or email ID or phone number: <\/strong>The first piece of information entered in the form; it could be any of these, depending on the app<\/li>\n\n\n\n<li><strong>Password:<\/strong> A secure field that masks the user\u2019s password<\/li>\n\n\n\n<li><strong>Submit button: <\/strong>This initiates and confirms the authentication process (assuming the provided details are correct)<\/li>\n\n\n\n<li><strong>\u2018Remember Me\u2019 checkbox: <\/strong>An option that allows the system to retain user credentials for future logins<\/li>\n\n\n\n<li><strong>\u2018Forgot Password\u2019 link: <\/strong>Offers a way to reset the password in case it\u2019s forgotten<\/li>\n\n\n\n<li><strong>Two-Factor Authentication (2FA): <\/strong>A second verification step, such as an OTP (one-time password) sent via SMS or email<\/li>\n\n\n\n<li><strong>Login with social accounts: <\/strong>Options to log in using third-party services like \u201cContinue with Google\u201d or \u201cLogin with Facebook\u201d<\/li>\n\n\n\n<li><strong>CAPTCHA or bot protection box: <\/strong>This prevents automated login attempts by verifying the user is a human<\/li>\n<\/ul>\n\n\n\n<p>Here\u2019s what TestGrid\u2019s login page looks like\u2014in addition to everything in the bullet list above, there\u2019s also an option to \u201cSign Up\u201d in case the user doesn\u2019t have an account:<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"1154\" height=\"616\" src=\"https:\/\/testgrid.io\/blog\/wp-content\/uploads\/2025\/04\/login-page-test-cases-testgrid.png\" alt=\"\" class=\"wp-image-13917\" loading=\"lazy\" title=\"\"><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>11 Types of Test Cases for Login Page<\/strong><\/h2>\n\n\n\n<p>Here are 11 login page test cases that you can write, covering different aspects of software testing:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Functional test cases<\/strong><\/h3>\n\n\n\n<p>To ensure the login functionality works exactly as intended, under both controlled and standard edge conditions, use the following test case example for login pages:<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>1. Login with valid\/invalid credentials<\/strong><\/h4>\n\n\n\n<p>Here, the goal is to confirm that a user can successfully log in with a valid username and password and to check what happens when they use invalid details.<\/p>\n\n\n\n<p><strong>Steps:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Open the login page<\/li>\n\n\n\n<li>Enter a valid username and valid password<\/li>\n\n\n\n<li>Click the Login button OR press Enter<\/li>\n\n\n\n<li>Observe the redirection behavior<\/li>\n\n\n\n<li>Repeat steps 1\u20134 with the following variations:\n<ul class=\"wp-block-list\">\n<li>Valid username, invalid password<\/li>\n\n\n\n<li>Invalid username, valid password<\/li>\n\n\n\n<li>Invalid username, invalid password<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>2. Session management post login<\/strong><\/h4>\n\n\n\n<p>In this test case example for login pages, let\u2019s confirm that a user session begins after login is managed securely.<\/p>\n\n\n\n<p><strong>Steps:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Log in with valid credentials<\/li>\n\n\n\n<li>Open Dev Tools \u2192 Inspect session cookie or token<\/li>\n\n\n\n<li>Refresh the page; ensure the user remains logged in<\/li>\n\n\n\n<li>Open the app in a new tab; verify the user is still authenticated<\/li>\n\n\n\n<li>Close and reopen the browser; if &#8220;Remember Me&#8221; was selected, confirm the session persists<\/li>\n<\/ul>\n\n\n\n<p><strong>Pro Tip: <\/strong>Log in from two devices and see if one invalidates the other (some systems force single-session policies).<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>3. Password flexibility<\/strong><\/h4>\n\n\n\n<p>To check your app can handle a wide variety of valid password formats, follow these steps:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Attempt login using passwords with:<\/li>\n\n\n\n<li>Special characters (e.g., P@ssw0rd!)<\/li>\n\n\n\n<li>Spaces (e.g., My Pass word)<\/li>\n\n\n\n<li>Mixed casing (e.g., PaSsWoRd)<\/li>\n\n\n\n<li>Minimum length (e.g., 6 characters if that\u2019s the rule)<\/li>\n\n\n\n<li>Maximum length (e.g., 64 characters if allowed)<\/li>\n<\/ul>\n\n\n\n<p><strong>Also Read: <\/strong><a href=\"https:\/\/testgrid.io\/blog\/test-case-design-techniques\/\">Test Case Design Techniques in Software Testing<\/a><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Negative test cases<\/strong><\/h3>\n\n\n\n<p>We\u2019ve said this before: real-world users are random; they don\u2019t follow any pattern while using the app. Negative testing prepares you for that.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>4. SQL injection attempt<\/strong><\/h4>\n\n\n\n<p>In this test case for login pages, we ensure that the login fields aren\u2019t vulnerable to SQL injection. The server should return a generic login error without revealing technical details, and the app shouldn\u2019t allow authorized access.<\/p>\n\n\n\n<p><strong>Steps:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Open the login page<\/li>\n\n\n\n<li>Enter SQL injection payloads in the username or password field, such as:\n<ul class=\"wp-block-list\">\n<li>\u2018 OR 1=1 &#8212;<\/li>\n\n\n\n<li>\u2018 UNION SELECT null,null &#8212;<\/li>\n\n\n\n<li>\u2018 OR \u2018x\u2019=\u2019x\u2019<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li>Submit the login form<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>5. Disabled account login<\/strong><\/h4>\n\n\n\n<p>What happens if users with suspended or deactivated accounts can\u2019t log in? No session should be created. No token should be issued.<\/p>\n\n\n\n<p><strong>Steps:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Use an admin panel or database script to deactivate a test account<\/li>\n\n\n\n<li>Attempt to log in using the deactivated account\u2019s credentials<\/li>\n\n\n\n<li>Inspect session or token behavior after submission<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>UI\/UX test cases<\/strong><\/h3>\n\n\n\n<p>It\u2019s essential to consider how your login page looks, feels, and behaves for the end user. <a href=\"https:\/\/testgrid.io\/visual-testing\">Visual testing<\/a> ensures that your app or site is intuitive, accessible, and consistent.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>6. Responsive design<\/strong><\/h4>\n\n\n\n<p>The goal here is to verify the login page adjusts gracefully across devices and screen sizes.&nbsp;<\/p>\n\n\n\n<p><strong>Steps:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Open the login page on:\n<ul class=\"wp-block-list\">\n<li>Desktop browser<\/li>\n\n\n\n<li>Tablet device<\/li>\n\n\n\n<li>Mobile phone (portrait + landscape)<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li>Rotate device orientation while on the login form<\/li>\n\n\n\n<li>Observe any layout shifts or input field cut-offs<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>7. Accessibility<\/strong><\/h4>\n\n\n\n<p>Can users with disabilities interact with your login form using assistive technologies? To find out, here\u2019s a test case example for login pages.<\/p>\n\n\n\n<p><strong>Steps:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Use keyboard navigation (Tab, Shift+Tab, Enter, Space) to access and activate all interactive elements in a logical focus order<\/li>\n\n\n\n<li>Validate focus indicators, ARIA labels, and accessible input attributes<\/li>\n\n\n\n<li>Run tools like Axe or Lighthouse to detect WCAG violations<\/li>\n\n\n\n<li>Screen reader compatibility (try NVDA, VoiceOver)<\/li>\n<\/ul>\n\n\n\n<p><strong>Pro Tip:<\/strong> \u201cForgot Password\u201d and \u201cSign Up\u201d links must be reachable by keyboard and clearly announced by screen readers.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Security test cases<\/strong><\/h3>\n\n\n\n<p>You want your login system to resist exploitation and ensure that users have a safe experience whenever they share their personal information. That\u2019s why security testing is important.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>8. HTTPS enforcement<\/strong><\/h4>\n\n\n\n<p>Ensure all login requests and responses are securely transmitted over HTTPS.<\/p>\n\n\n\n<p><strong>Steps:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Try accessing the login page via http:\/\/yourapp.com\/login<\/li>\n\n\n\n<li>Observe if the request is redirected or blocked<\/li>\n\n\n\n<li>Open browser Dev Tools \u2192 Network tab and inspect request protocol<\/li>\n<\/ul>\n\n\n\n<p>The page should automatically redirect to \u201chttps:\/\/.\u201d<\/p>\n\n\n\n<p><strong>Pro Tip: <\/strong>Use HSTS headers to enforce secure protocol even on first access.&nbsp;<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>9. CAPTCHA integration<\/strong><\/h4>\n\n\n\n<p>CAPTCHA helps detect and block bot-based login attempts.<\/p>\n\n\n\n<p><strong>Steps:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Trigger CAPTCHA by:\n<ul class=\"wp-block-list\">\n<li>Repeated failed logins<\/li>\n\n\n\n<li>Logging in from a suspicious IP<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li>Interact with CAPTCHA (image\/audio)<\/li>\n\n\n\n<li>Attempt login without solving the CAPTCHA<\/li>\n\n\n\n<li>Solve CAPTCHA and attempt to log in again<\/li>\n<\/ul>\n\n\n\n<p><strong>Good Practice: <\/strong>Don\u2019t always show CAPTCHA. Trigger it contextually. For instance, if the system notices suspicious behavior (maybe 5 failed login attempts from the same IP address within 10 minutes), then initiate CAPTCHA.<\/p>\n\n\n\n<p><strong>Also Read: <\/strong><a href=\"https:\/\/testgrid.io\/blog\/test-cases-for-ecommerce-website\/\">Test Cases for Ecommerce Websites<\/a><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Performance and load test cases<\/strong><\/h3>\n\n\n\n<p>Is your login page on the mobile app or website stable and fast? Can it sustain itself even when users flood in? That\u2019s what these tests help you gauge.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>10. Concurrent logins<\/strong><\/h4>\n\n\n\n<p>The goal is to assess how the page behaves under simultaneous login attempts. Here\u2019s a test case example for login pages.<\/p>\n\n\n\n<p><strong>Steps:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Simulate 1000+ concurrent users logging in within 1\u20132 minutes<\/li>\n\n\n\n<li>Observe response times, success\/failure rates, server errors<\/li>\n\n\n\n<li>Monitor database load, backend CPU, and memory usage<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>11. Login response time<\/strong><\/h4>\n\n\n\n<p>This test case comes in handy for measuring how long the login flow takes across devices and networks under normal and peak conditions.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Steps:<\/strong><\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Measure end-to-end response time from form submission to full dashboard render including authentication and backend processing:\n<ul class=\"wp-block-list\">\n<li>On desktop<\/li>\n\n\n\n<li>On mobile<\/li>\n\n\n\n<li>On slow networks (e.g., 3G)<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li>Record performance on low-end devices and browsers<\/li>\n<\/ul>\n\n\n\n<p><strong>Ideal Target: <\/strong>Login flows should ideally respond in under 2 seconds.<\/p>\n\n\n\n<p><strong>Also Read: <\/strong><a href=\"https:\/\/testgrid.io\/blog\/test-case-template\/\">Free Test Case Template Examples and Formats<\/a><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Best Practices for Writing Test Cases for Login Pages<\/strong><\/h2>\n\n\n\n<p>Now that you know the different test cases of login pages to focus on, the next step is writing. They should be structured with clarity, purpose, and reusability in mind. After all, that\u2019s what determines the long-term value of test cases.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>1. Draft clear and descriptive test case steps<\/strong><\/h3>\n\n\n\n<p>Your test cases should be written so that anyone, a new QA hire, a developer doing a hotfix, or a non-technical stakeholder, can immediately follow them.<\/p>\n\n\n\n<p>That\u2019s the bar you should aim for. Use simple, consistent language and break down steps logically, no matter how small or trivial they may seem. For example, if a specific user is needed, document it. If the test case requires the user to be logged out beforehand, mention that.<\/p>\n\n\n\n<p>Don\u2019t assume prior knowledge. Use a short \u201cPreconditions\u201d section at the top of each test case so expectations are set from the start. Test cases for login pages that fail due to missing context are frustrating and time-consuming.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>2. Include both positive and negative scenarios<\/strong><\/h3>\n\n\n\n<p>Testing only what should happen isn\u2019t enough. You should also cover what shouldn\u2019t happen when writing a test case for login pages.<\/p>\n\n\n\n<p>While positive test cases verify valid behaviors like successful logins or password resets, negative ones test how the system handles invalid inputs, attack attempts, and broken flows. By capturing both sides, you build confidence in the reliability of the login page.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>3. Prioritize security-related test cases<\/strong><\/h3>\n\n\n\n<p>Because your login page is a gateway to everything in your app or site, it is a prime target for malicious users. That\u2019s why you should include test cases that directly address threats like weak password enforcement, brute-force attempts, and SQL injection.<\/p>\n\n\n\n<p>When <a href=\"https:\/\/testgrid.io\/blog\/how-to-write-test-cases\/\">writing test cases<\/a> for login pages, Consider session expiration, secure cookie attributes (HttpOnly, Secure, SameSite), token storage, and error message sanitization.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>4. Test across devices, browsers, and screen sizes<\/strong><\/h3>\n\n\n\n<p>With so many different devices, versions, and operating systems at play, you can\u2019t assume your users will only log in to your app via Chrome on a desktop. That\u2019s too narrow. Broaden your horizon. Consider questions like:<\/p>\n\n\n\n<p>What happens if a small mobile screen on Safari is used to log in?<\/p>\n\n\n\n<p>Do session cookies persist in Firefox the same way they do in Edge?<\/p>\n\n\n\n<p>How does the login page layout look on a tablet?<\/p>\n\n\n\n<p>Your test cases should reflect the reality of your user base. This also includes accessibility\u2014look at aspects like screen reader behavior and keyboard navigation to ensure your login is truly inclusive. Make the login pages always work for everyone.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>5. Automate repetitive or data-driven test cases<\/strong><\/h3>\n\n\n\n<p>Well-written test cases should identify which are good candidates for automation and which aren\u2019t. Why spend time manually on the same flows that can be scripted once and reused across builds? Focus that energy on exploratory flows, UI glitches, and edge cases that demand hybrid testing assistance.<\/p>\n\n\n\n<p>For example, the case for verifying login rate limits or lockout after multiple failed attempts can be automated. However, checking for localized text alignment or cultural nuances in translated versions may require human expertise. Create your <a href=\"https:\/\/testgrid.io\/blog\/test-automation-strategy\/\">test automation strategy<\/a> accordingly.<\/p>\n\n\n\n<p><strong>Also Read: <\/strong><a href=\"https:\/\/testgrid.io\/blog\/test-case-design-techniques\/\">Key Test Cases &amp; Best Practices for Testing Food Delivery Apps<\/a><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Automate Login Test Cases the Easy Way: A Step-by-Step Guide to Using TestGrid<\/strong><\/h2>\n\n\n\n<p><a href=\"https:\/\/testgrid.io\">TestGrid<\/a> is an AI-powered end-to-end testing platform that lets you build and run test cases quickly, even if your team lacks heavy coding expertise.

Ensure the login flow works consistently for all users, whether they\u2019re using Chrome for Android or Edge for Windows.<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Load and <\/strong><a href=\"https:\/\/testgrid.io\/solutions\/performance-testing\"><strong>performance testing<\/strong><\/a><strong>: <\/strong>Simulate high-concurrency login attempts, slow API responses, backend bottlenecks, and infrastructure limitations during peak usage using TestGrid\u2019s integrated load testing.<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Functional testing: <\/strong>With TestGrid\u2019s no-code and low-code test automation, you can automate core login use cases, such as password visibility toggle, redirection after login, and error message display. Once automated, these tests can be reused across multiple builds and environments.<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>CI\/CD integration: <\/strong>Integrate TestGrid with common CI\/CD platforms, such as Jenkins, CircleCI, or GitHub Actions, to make your login tests run automatically as part of your CI\/CD pipeline. Catch authentication and session management issues (e.g., invalid token handling, and expired sessions) before deploying to production\u2014ideal for fast-moving Agile teams.<\/li>\n<\/ul>\n\n\n\n<p>Another major USP of TestGrid is <a href=\"https:\/\/testgrid.io\/cotester\">CoTester<\/a>, the world\u2019s first AI testing agent. It\u2019s pre-trained on advanced software testing fundamentals and the Software Development Life Cycle (SDLC). Unlike other syntax-driven AI tools, it understands natural language commands.<\/p>\n\n\n\n<p>Simply upload PDFs, Word Docs, or CSVs containing login-related user stories or requirements for contextual test generation. The CoTester will read and understand the context and generate accurate, aligned test cases.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/lh7-rt.googleusercontent.com\/docsz\/AD_4nXfckqjbRLyMdve01IbhVoPe5BZvuh35aY3WJGWpFYrTBHHzUY1afEsUeASROET2sd2QYld59IKiJt7WYZdDfanPgshkcZw8xj7KU_ljzd8l-R1ehPcpI1srSNNexv_mqJ0hAq1dKQ?key=8NtYsssMtact-0Wjz2x9c74k\" alt=\"\" loading=\"lazy\" title=\"\"><\/figure>\n\n\n\n<p>You can also paste a URL like \u2018https:\/\/example.com\/login\u2019 for this AI agent to analyze the page structure, extract input fields, and auto-generate relevant test cases. After CoTester generates test cases, edit or reorder steps manually, add custom data, and modify assertions.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/lh7-rt.googleusercontent.com\/docsz\/AD_4nXfikYc607vedmcRSI_tlPIHoOYMof4OLuNXt3tFLZhD8HG57CHG8bGUzmwC860iLKVLuS1Z6Q9pLSVIn3mpHJubw1bysD0b5qYY0cT8ggItUce1Jnt1XJklGsXekuaMNYMusbHLDA?key=8NtYsssMtact-0Wjz2x9c74k\" alt=\"\" loading=\"lazy\" title=\"\"><\/figure>\n\n\n\n<p>In addition, all data remains confined to your organization.

What\u2019s the difference between test scenarios and test cases for a login page?<\/strong><\/h3>\n\n\n\n<p>A test scenario is a high-level idea of what to test, like \u201ctest login with invalid credentials.\u201d On the other hand, a test case for login pages breaks that down into concrete steps, expected results, inputs, and preconditions. Scenarios guide your thinking, but test cases help you execute.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>2. How often should I review or update my login test cases?<\/strong><\/h3>\n\n\n\n<p>Review test cases whenever authentication logic, third-party login (OAuth\/SAML), session handling, or UI layout changes. This includes design changes, new validations, additions of Multi-Factor Authentication (MFA), and password policy updates.<\/p>\n\n\n\n<p>Another best practice is to plan to audit your test cases of login pages at least once per release cycle. This will help remove outdated logic and account for new edge cases regardless of the circumstances.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>3. Should test cases for login pages use realistic data?<\/strong><\/h3>\n\n\n\n<p>Yes. While it\u2019s easy to write test cases that use \u201ctest@test.com\u201d or \u201cpassword123\u201d repeatedly, you need to remember that real users don\u2019t operate like that; they don\u2019t follow neat patterns.&nbsp;<\/p>\n\n\n\n<p>That\u2019s why it\u2019s vital to incorporate usernames with special characters, uncommonly long inputs, and complex password formats. This approach will help you uncover problems around storage limits, form validations, and character-handling logic.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>4. How many test cases are enough for a login page?<\/strong><\/h3>\n\n\n\n<p>There\u2019s no fixed number. A solid baseline includes at least 8\u201310 functional cases covering inputs like empty fields, invalid characters, max-length constraints, and session expiry handling, plus security, UI\/UX, negative, and cross-platform tests. It\u2019s not about quantity; it\u2019s about ensuring proper test coverage. Therefore, make sure your test cases include the riskiest, most-used, and most-abused flows.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A login page is the first line of defense in any website or application.
