Enforcing Strong Passwords in Laravel

Securing user accounts starts with strong passwords, and Laravel makes this easier by providing a Password validation rule.

This built-in feature allows you to enforce robust password policies to improve application security. Let’s explore how you can use this feature effectively.

Using the Password Validation Rule
The Password rule in Laravel includes several methods to enforce password complexity. Here’s a quick example:

Example in a Form Request

use Illuminate\Foundation\Http\FormRequest;
use Illuminate\Validation\Rules\Password;

class RegisterRequest extends FormRequest
{
    public function rules()
    {
        return [
    'password' => [
        'required',
        'string',
        Password::min(8) // Minimum length of 8 characters
            ->mixedCase() // Must include both uppercase and lowercase letters
            ->letters()   // Must include at least one letter
            ->numbers()   // Must include at least one number
            ->symbols()   // Must include at least one symbol
            ->uncompromised(), // Checks against known data breaches
    ],
        ];
    }
}

Explanation of Methods

• min(8): Sets the minimum password length.
• mixedCase(): Requires at least one uppercase and one lowercase letter.
• letters(): Ensures at least one alphabetic character is present.
• numbers(): Enforces at least one numeric digit.
• symbols(): Requires at least one special character (e.g., @, #, $).
• uncompromised(): Validates the password against the Have I Been Pwned database to ensure it hasn’t been exposed in a data breach.

Customizing Validation Messages

To make the validation messages user-friendly, you can customize them in the validation.php language file:

// resources/lang/en/validation.php
'password' => [
    'letters' => 'The :attribute must contain at least one letter.',
    'mixed' => 'The :attribute must contain at least one uppercase and one lowercase letter.',
    'numbers' => 'The :attribute must contain at least one number.',
    'symbols' => 'The :attribute must contain at least one symbol.',
    'uncompromised' => 'The :attribute has been compromised. Please choose a different :attribute.',
],

This ensures users receive clear feedback when their password doesn’t meet the requirements.
