FAQ

What makes a password strong?

A strong password is typically at least 12 characters long, includes a mix of uppercase and lowercase letters, numbers, and symbols, and avoids common words or predictable patterns.

Is my password stored or transmitted?

No. The password is processed entirely in your browser. We do not store, log, or transmit your password to any server.

Can I use this tool for security audits?

Yes, security auditors can use it to quickly assess password policies or test sample passwords. However, for production audits, consider using dedicated password cracking tools.

What does the strength rating mean?

Weak passwords are easily guessed or cracked. Medium passwords offer moderate security but can be improved. Strong passwords are resistant to common attacks and are recommended for sensitive accounts.
