FAQ
How are passwords and tokens generated?
Secure random generation uses the Web Crypto API (crypto.getRandomValues) which provides cryptographically strong random values, making generated passwords and tokens suitable for security purposes.
Is my data safe when using security tools?
Absolutely. All security operations including password generation, hashing, and encryption happen entirely in your browser. No sensitive data is ever transmitted over the network.
How strong are the generated passwords?
Generated passwords can include uppercase, lowercase, numbers, and special characters. A 16-character password with all character types has approximately 95 bits of entropy, which is considered very strong.
