Strong Password Generator
Generate strong, unpredictable random passwords with the Web Crypto API.
Why strong passwords matter
Weak and reused passwords are the most common reason accounts get hijacked. Passwords like '123456' or ones containing a birth date can be cracked in seconds, while a long random password withstands brute-force attacks for years.
Cryptographically secure
Passwords are created with your browser's cryptographically secure random generator (Web Crypto API), not predictable methods like Math.random. Generated passwords are never sent to a server or saved.
Options
- Password length
- Upper case, lower case, digits and symbols

Use at least 16 characters for email, banking and social accounts and store them in a password manager.
