💡 Why This Matters

🌍 Real World

Remember me functionality is common in websites to improve user experience by keeping users logged in across sessions.

💼 Career

Understanding authentication and session management is essential for backend web developers working with Laravel or similar frameworks.

1

Create the login form

Create a Blade view file called login.blade.php with a form containing inputs for email, password, and a checkbox named remember. The form should use the POST method and submit to /login.

Laravel

    @csrf
    

Hint

Use @csrf for security. Add inputs for email, password, and a checkbox named remember.

2

Add the login route and controller method

In routes/web.php, add a POST route for /login that uses LoginController@login. Then, create a LoginController with a login method that accepts the request.

Laravel

    @csrf
    Email:
    

    Password:
    

    
         Remember Me
    

    Login


// Add route and controller method below
// Your code here

Hint

Add a POST route for /login in routes/web.php. Create LoginController with a login method that accepts Request $request.

3

Implement login logic with remember me

In the login method of LoginController, use Auth::attempt with the email, password from the request, and the remember checkbox value. If authentication succeeds, redirect to /dashboard. Otherwise, redirect back with errors.

Laravel

    @csrf
    Email:
    

    Password:
    

    
         Remember Me
    

    Login


// routes/web.php
use App\Http\Controllers\LoginController;

Route::post('/login', [LoginController::class, 'login']);

// app/Http/Controllers/LoginController.php
namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;

class LoginController extends Controller
{
    public function login(Request $request)
    {
        // Use Auth::attempt with email, password, and remember
        // Redirect to /dashboard on success
        // Redirect back with errors on failure
        // Your code here
    }
}

Hint

Use $request->only('email', 'password') to get credentials. Use $request->has('remember') for the checkbox. Pass both to Auth::attempt. Redirect accordingly.

4

Add the dashboard route and view

Add a GET route for /dashboard in routes/web.php that returns a simple view called dashboard. Create a Blade view file dashboard.blade.php with a heading Welcome to your dashboard.

Laravel

    @csrf
    Email:
    

    Password:
    

    
         Remember Me
    

    Login


// routes/web.php
use App\Http\Controllers\LoginController;

Route::post('/login', [LoginController::class, 'login']);

// Add GET route for /dashboard below
// Your code here

// resources/views/dashboard.blade.php

Hint

Add a GET route for /dashboard that returns the dashboard view. Create dashboard.blade.php with a heading inside the body tag.

Practice

1. What does the "Remember me" functionality do in Laravel authentication?

easy

A. Keeps users logged in across browser sessions

B. Logs users out immediately after closing the browser

C. Deletes user data after logout

D. Prevents users from logging in multiple times

Solution

1. Step 1: Understand the purpose of "Remember me"

   It is designed to keep users logged in even after they close and reopen their browser.

2. Step 2: Compare options with this purpose

   Only Keeps users logged in across browser sessions matches this behavior; others describe opposite or unrelated actions.

3. Final Answer:

   Keeps users logged in across browser sessions -> Option A

4. Quick Check:

   Remember me = Keeps login [OK]

Hint: Remember me means staying logged in after browser closes [OK]

Common Mistakes:

• Thinking it logs users out immediately
• Confusing it with session expiration
• Assuming it deletes user data

2. Which is the correct way to enable "Remember me" when using Auth::attempt in Laravel?

easy

A. Auth::attempt(['email' => $email, 'password' => $password]);

B. Auth::attempt(['email' => $email, 'password' => $password], true);

C. Auth::attempt(['email' => $email, 'password' => $password], false);

D. Auth::attempt(['email' => $email, 'password' => $password], 0);

Solution

1. Step 1: Check Auth::attempt signature

   The second parameter is a boolean to enable "Remember me"; true enables it.

2. Step 2: Identify correct syntax

   Auth::attempt(['email' => $email, 'password' => $password], true); uses true correctly. Omitting the second parameter defaults to false and disables it. Using false explicitly disables it. Using 0 is falsy and disables it.

3. Final Answer:

   Auth::attempt(['email' => $email, 'password' => $password], true); -> Option B

4. Quick Check:

   Second param true enables remember me [OK]

Hint: Use true as second param in Auth::attempt for remember me [OK]

Common Mistakes:

• Omitting the second parameter
• Passing false instead of true
• Using numeric 0 instead of true

3. Given this Laravel code snippet, what will be the output if the user checks "Remember me" and credentials are correct?

if (Auth::attempt(['email' => $email, 'password' => $password], true)) {
    echo 'Logged in with remember me';
} else {
    echo 'Login failed';
}

medium

A. Logged in with remember me

B. Login failed

C. Syntax error

D. User logged in but not remembered

Solution

1. Step 1: Analyze Auth::attempt with remember true

   When credentials are correct and remember is true, Auth::attempt returns true and sets a long-lasting cookie.

2. Step 2: Check output based on condition

   Since Auth::attempt returns true, the first echo runs, printing 'Logged in with remember me'.

3. Final Answer:

   Logged in with remember me -> Option A

4. Quick Check:

   Correct credentials + remember true = logged in message [OK]

Hint: Correct credentials + true = logged in with remember me [OK]

Common Mistakes:

• Assuming remember me disables login
• Confusing output with login failure
• Thinking it causes syntax error

4. Identify the error in this Laravel login code that tries to enable "Remember me":

if (Auth::attempt(['email' => $email, 'password' => $password], 'true')) {
    return redirect()->intended('dashboard');
}

medium

A. Redirect method is incorrect

B. The email key should be 'user_email' instead of 'email'

C. Auth::attempt does not accept a second parameter

D. The second parameter should be boolean true, not string 'true'

Solution

1. Step 1: Check second parameter type in Auth::attempt

   The second parameter must be boolean true or false, not a string.

2. Step 2: Verify other parts

   Email key 'email' is correct; Auth::attempt accepts second param; redirect()->intended is valid.

3. Final Answer:

   The second parameter should be boolean true, not string 'true' -> Option D

4. Quick Check:

   Second param must be boolean, not string [OK]

Hint: Use true boolean, not 'true' string for remember me [OK]

Common Mistakes:

• Passing 'true' as string instead of boolean
• Changing email key incorrectly
• Thinking redirect()->intended is wrong

5. You want to implement "Remember me" in a Laravel app but also ensure security by limiting the cookie duration. Which approach correctly combines remember me with a custom cookie lifetime?

hard

A. Use Auth::login with remember true and override the cookie expiration in the AuthServiceProvider

B. Use Auth::attempt with remember true and manually set cookie expiration in middleware

C. Use Auth::attempt with remember true and set 'remember' in config/session.php

D. Use Auth::attempt without remember and set session lifetime to a long time

Solution

1. Step 1: Understand Laravel remember me and cookie lifetime

   Laravel uses the 'remember' config setting in config/session.php to control the remember me cookie lifetime.

2. Step 2: Identify correct way to combine remember me and cookie duration

   Using Auth::attempt with remember true plus setting 'remember' in config/session.php is the standard way.

3. Step 3: Evaluate other options

   Manual cookie setting or overriding in AuthServiceProvider is complex and not recommended; omitting remember disables feature.

4. Final Answer:

   Use Auth::attempt with remember true and set 'remember' in config/session.php -> Option C

5. Quick Check:

   Remember me + config cookie time = secure persistent login [OK]

Hint: Set 'remember' in config/session.php with Auth::attempt true [OK]

Common Mistakes:

• Trying to manually set cookie expiration in code
• Not using remember parameter in Auth::attempt
• Confusing session lifetime with remember cookie lifetime
