What is Random Password Generator?

Pick a length and which character types to include (uppercase, lowercase, numbers, symbols), and get a random password instantly. Uses crypto.getRandomValues(), the same cryptographically secure randomness source browsers use for security-sensitive operations, not the weaker Math.random(). Everything happens in your browser. The password is never sent anywhere, logged, or stored — copy it and it's yours alone.

FAQ

It's generated with crypto.getRandomValues(), a cryptographically secure random number source suitable for real passwords, not a toy generator. Combined with sufficient length and character variety, it produces genuinely strong passwords.

16 characters with all character types enabled is a solid default for most accounts. Use longer (20+) for particularly sensitive accounts, and always prefer a password manager over memorizing passwords.

Removing a character type (e.g. symbols) shrinks the pool of possible characters per position, which lowers the total number of possible passwords at a given length — so strength drops even if the length stays the same.
