How to create a password and check the password validation using Laravel framework in the easy way

Creating a strong password is crucial for protecting sensitive information and preventing unauthorized access. In this article, we will walk you through how to create a password and check password validation using Laravel, a popular PHP web application framework.

Creating a Password

When creating a password, it's important to follow some best practices to ensure it is strong and secure. Here are some tips for creating a strong password:

• Use a combination of upper and lowercase letters, numbers, and symbols.
• Avoid using common dictionary words or phrases.
• Use a password that is at least 12 characters long.
• Don't reuse passwords across different accounts.
• Consider using a password manager to generate and store strong passwords.

In Laravel, you can create a password using the built-in Hash facade. The Hash facade provides methods for hashing and verifying passwords.

To create a password, you can use the make() method on the Hash facade. Here's an example:

$password = Hash::make('my-password');

This will generate a hashed version of the password that you can store in your database.

Checking Password Validation

In addition to creating a strong password, you also want to ensure that the user's password meets certain validation rules when they are creating an account or changing their password. Laravel provides a built-in validation rule called password that you can use to validate passwords.

To use the password validation rule, you can add it to your validation rules array like this: 

$request->validate([
    'password' => ['required', 'confirmed', Rules\Password::defaults()],
]);

This will ensure that the password is required, confirmed (i.e., the user enters it twice to prevent typos), and meets the default password rules. The default rules require a minimum length of 8 characters, at least 1 uppercase letter, 1 lowercase letter, and 1 digit.

You can also customize the password validation rules to suit your specific requirements. For example, if you want to require a password with at least 12 characters, you can use the min rule like this:

$request->validate([
    'password' => ['required', 'confirmed', 'min:12', Rules\Password::defaults()],
]);

Check the Password is Correct

you can check if a password is correct using the check method on the Hash facade. Here's an example: 

if (Hash::check('plain-text-password', $hashedPassword)) {
    // Password is correct
} else {
    // Password is incorrect
}

In this example, the Hash::check method takes two arguments: the plain-text password entered by the user, and the hashed version of the password stored in the database.

If the plain-text password matches the hashed password, the check method will return true, indicating that the password is correct. If the passwords do not match, the method will return false, indicating that the password is incorrect. 

Conclusion

Creating and validating strong passwords is an important aspect of securing your web application. With Laravel's built-in Hash facade and password validation rule, it's easy to create and validate secure passwords. By following best practices and using these tools, you can help protect your users' sensitive information and prevent unauthorized access to your application.
