Common questions

Are keys uploaded or stored?

No. Keys are generated in this browser tab. Bento Tools does not send them to a server or keep a history.

Which alphabet should I use?

Base62 is a solid general default. Hex is convenient for binary-looking tokens. Base32 and base64url help when you need URL-safe or case-insensitive alphabets.

What does the bit estimate mean?

It is approximate entropy from length × alphabet size. It is a rough guide, not a guarantee for every threat model.

Is the API Key Generator free?

Yes. It is a free Bento Tools utility with no account required.
