Frequently Asked Questions
How secure are these passwords?
Very secure. Passwords are generated using the Web Crypto API, which provides cryptographically secure random values. A 20-character password with all options enabled has over 130 bits of entropy.
Are my passwords stored anywhere?
No. Generation happens 100% in your browser. No passwords are ever sent to any server, stored in any database, or logged in any way.
What makes a strong password?
A strong password is long (16+ characters), uses a mix of uppercase, lowercase, numbers, and symbols, and is randomly generated rather than based on dictionary words.
What is entropy?
Entropy measures the unpredictability of a password in bits. Higher entropy means more possible combinations. A password with 80+ bits of entropy is considered very strong.
