Frequently Asked Questions
Yes. We use the Web Crypto API which provides cryptographically secure random numbers. These are suitable for security-sensitive applications like passwords and tokens.
At least 12 characters for regular accounts, 16+ for sensitive accounts. Each additional character exponentially increases the time needed to crack it.
Special characters dramatically increase password strength. A 12-character password with special characters is much stronger than a 12-character alphanumeric password.
Yes, the cryptographic randomness is suitable for production use. However, for critical systems, consider using your platform's built-in secure random generators.
