Frequently asked questions

Is it safe to generate passwords online here?
Yes. Everything is generated locally in your browser with crypto.getRandomValues — nothing is sent to our servers or stored.
How long should an API key be?
At least 128 bits of randomness; this tool uses 32 alphanumeric characters (~190 bits).
Is the API Key Generator free?
Yes. The API Key Generator is 100% free with no sign-up and no usage limits for template-based results. AI-powered results have a generous daily limit to keep the service free for everyone.
Do you store what I type?
Generators that run in your browser never send your input anywhere. AI generators send your prompt to our server only to create results; we do not sell or share it.
