Frequently Asked Questions

This tool uses the Web Crypto API (crypto.getRandomValues) which provides cryptographically secure random numbers suitable for security-sensitive applications.

Password strength comes from length and randomness. A 16+ character password with mixed cases, numbers, and symbols is extremely difficult to crack.

Yes. Passwords are generated entirely in your browser. Nothing is sent to any server. Close the tab and the password exists only in your clipboard.

Generally yes, unless a site has restrictions. More character types increase entropy. A 12-char password with all types is stronger than a 12-char alphabetic-only password.

At least 12 characters, ideally 16+. Each additional character exponentially increases security. Modern password managers make long passwords easy to use.

Entropy measures password unpredictability in bits. Higher entropy = harder to crack. A 16-character password with all character types has 95+ bits of entropy—strong enough to resist brute-force for centuries.

Enable this if you'll type the password manually. Characters like 'O' and '0', 'l' and '1' are easily confused. For password managers where you copy-paste, ambiguous characters are fine.

Never. If one account is breached, attackers try those credentials everywhere. Use a unique password for each account and store them in a password manager.

Yes. Reputable password managers (Bitwarden, 1Password, LastPass) use encryption and are much safer than reusing weak passwords or writing them down. They're essential for managing unique, strong passwords.

Use the maximum allowed length and all permitted character types. Some sites have overly restrictive rules—feedback to those sites that longer passwords improve security, not harm it.
