Answer

Previous Question

To enforce strong password policies in web applications, implement server-side validation that checks for complexity, length, and uniqueness of passwords. Additionally, consider using client-side validation for immediate feedback.

<!-- BEGIN COPY / PASTE -->
    function validatePassword(password) {
      const minLength = 8;
      const hasUpperCase = /[A-Z]/.test(password);
      const hasLowerCase = /[a-z]/.test(password);
      const hasNumbers = /[0-9]/.test(password);
      const hasSpecialChars = /[!@#\$%\^\&*\)\(+=._-]/.test(password);

      return password.length >= minLength && hasUpperCase && hasLowerCase && hasNumbers && hasSpecialChars;
    }
    <!-- END COPY / PASTE -->

Additional Comment:

Always perform password validation on the server to prevent bypassing through client-side manipulation.
Consider using password strength meters to guide users in creating strong passwords.
Regularly update your password policy to adapt to evolving security threats.
