What Is a Password Generator?
A password generator creates strong, cryptographically random passwords that are virtually impossible to guess or crack. Good passwords use a mix of uppercase letters, lowercase letters, numbers, and symbols in random order. Tooliva's free online password generator creates secure passwords instantly using the Web Crypto API for true randomness.

Frequently Asked Questions
Q: How long should a password be?
For most accounts, 16–20 characters is recommended. For high-security accounts, 24–32 characters provides exceptional protection. Never use passwords shorter than 12 characters.
Q: Is the password stored anywhere?
No. The password is generated in your browser using the Web Crypto API and is never sent to any server. It exists only in your browser until you copy it.
Q: Are generated passwords guessable?
No. Cryptographically random passwords have no patterns and cannot be guessed by humans or brute-force attacks within any reasonable timeframe.
Q: Should I use a password manager?
Yes. Generate a unique strong password for each account and store them in a reputable password manager like Bitwarden, 1Password, or KeePass.
