Previous Question Next Question

To enforce strong password policies on your website, you should implement both client-side and server-side validation that checks for complexity, length, and uniqueness of passwords.

<!-- BEGIN COPY / PASTE -->
    // Example of server-side password policy enforcement
    function isPasswordStrong(password) {
      const minLength = 8;
      const hasUpperCase = /[A-Z]/.test(password);
      const hasLowerCase = /[a-z]/.test(password);
      const hasNumbers = /\d/.test(password);
      const hasSpecialChars = /[\W_]/.test(password);
      
      return password.length >= minLength && hasUpperCase && hasLowerCase && hasNumbers && hasSpecialChars;
    }
    <!-- END COPY / PASTE -->

Additional Comment:

Ensure passwords are at least 8 characters long and include a mix of upper and lower case letters, numbers, and special characters.
Implement rate limiting and account lockout mechanisms to prevent brute force attacks.
Consider using password strength meters on the client-side to guide users in creating strong passwords.
