Frequently asked questions
How random are the generated strings?
They use the Web Crypto API (crypto.getRandomValues), which draws from your operating system’s secure random source — the same quality of randomness used for encryption keys. That makes it suitable for tokens, temporary passwords and API-style keys, unlike simple Math.random() generators.
Can I use this to generate passwords or tokens?
Yes. Because the randomness is cryptographically secure and generated locally in your browser, the strings are safe to use as passwords, session tokens or one-off secrets. For memorable passwords with specific site rules, a dedicated password generator may be more convenient.
Is the generated string stored or logged anywhere?
No. The string is created in your browser and only exists on your screen and clipboard. Nothing is sent to a server, so there is no log of what you generated.
What length should I choose?
For passwords, 16+ characters with mixed character sets is a good baseline. For tokens or keys where you want roughly 128 bits of entropy, use at least 22 characters of mixed letters and digits, or 32 hex-style characters.
