What's the best way to enforce strong password policies in a web application?
Asked on Dec 14, 2025
Answer
To enforce strong password policies in a web application, you should implement server-side validation that checks for complexity, length, and uniqueness, while also providing user feedback on password strength.
Example Concept: A strong password policy typically requires a minimum length (e.g., 8-12 characters), a mix of uppercase and lowercase letters, numbers, and special characters. It also avoids common words and sequences. Implement these checks on the server-side to ensure consistency and security.
Additional Comment:
- Use a password strength meter on the client-side to guide users in creating strong passwords.
- Store passwords securely using a strong hashing algorithm like bcrypt.
- Regularly review and update password policies to adapt to new security threats.
