Frequently Asked Questions

Is it safe to use this password checker?

Absolutely! Our password strength checker runs entirely in your browser. Your password is never sent over the internet or stored anywhere. This ensures complete privacy and security.

What makes a password strong?

A strong password is long (14+ characters), uses a mix of uppercase, lowercase, numbers, and symbols, avoids common words and patterns, and is unique to each account. Our tool evaluates all these factors to determine password strength.

How often should I change my passwords?

Current security best practices recommend changing passwords only when there's evidence of compromise. Instead of frequent changes, focus on creating strong, unique passwords for each account and enabling two-factor authentication.

Can I use this tool on mobile devices?

Yes, our password strength checker is fully responsive and works perfectly on all devices including smartphones and tablets. The interface is optimized for touch interaction.
