Real randomness, made on your device
Ordinary random functions in programming languages are fine for games but predictable enough to be a problem for passwords. All the generators here use the Web Crypto API built into your browser, the same source of randomness used for secure connections. And because the values are created on your computer or phone, we never see them.
What you can generate
- Password Generator: long, random passwords with the character types you choose.
- Random Number Generator: pick winners, roll dice or draw lottery style numbers.
- UUID Generator: version 4 UUIDs for databases, tests and APIs.
