Choose your options and hit Generate.
Nothing is sent to a server and we never save/store any results. Refresh and they're gone — copy what you need.
Generated on your device with crypto.getRandomValues, using rejection sampling to avoid modulo bias.
Promo codes, API tokens, temporary passwords, seat-lock keys — live-event tech runs on random strings, and most are made badly: too short, too guessable, or copied from the last one.
Generate as many as you need below. Choose the length and character sets, decide whether every string must be unique, and copy the results. Everything is generated locally in your browser using its cryptographic random source — nothing is sent to us or anyone else.
Cryptographically random
Built on your browser's crypto.getRandomValues — the same source used for real security tooling, not Math.random().
Your character sets
Mix digits, upper- and lowercase letters and symbols; exclude look-alike characters for codes people have to type.
Batches, unique if you like
Generate up to 500 strings at once, optionally guaranteed unique — ideal for promo codes and one-time keys.
Nothing leaves your device
No server call, no logging, no storage. Close the tab and the strings are gone unless you kept them.
For anyone who needs a password, token or batch of codes right now, without trusting a stranger's website with them.
