How secure is this password generator?

Extremely secure. We use the Web Crypto API's cryptographically strong random number generator (CSPRNG), making the results significantly safer than standard generators.

Are my passwords stored on your server?

Never. All computation happens locally on your computer or mobile phone. We have no backend storage for your generated data.

What is a strong password length?

For maximum security in 2026, we recommend at least 16 to 20 characters mixed with uppercase, lowercase, numbers, and symbols.
