Password Generator
Generate strong, random passwords with custom length and character requirements, instantly in your browser.
How to use the Password Generator
- Set the password length. 16 or more characters is recommended.
- Choose which character types to include: uppercase, lowercase, numbers and special characters.
- Optionally exclude look-alike characters such as l, 1, O and 0 if you'll type the password by hand.
- Choose how many passwords to generate and click Run.
How the Password Generator works
The character types you tick are combined into one pool, and each character of the password is picked from that pool using your browser's cryptographically secure random number generator (the Web Crypto API). Nothing is sent to a server or stored.
Strength comes from length and randomness. A 16-character password drawn from about 90 possible characters has over 100 bits of entropy, far beyond what brute-force attacks can try. Use a different password for every account and keep them in a password manager.
