How to use 2FA / TOTP Secret Generator

Click generate, and the tool creates a cryptographically random Base32 secret plus an otpauth:// URI you can scan into Google Authenticator, Authy, or any TOTP app.

Frequently asked questions

Is the generated secret cryptographically secure?

Yes, it's generated with your browser's Web Crypto API, the same secure random source real authenticator apps rely on.

Is this generated securely enough to actually use?

Yes. Generation uses your browser's cryptographically secure random source (Web Crypto API), not a predictable pseudo-random function.

Does this tool send anything to a server?

No. Everything is generated entirely client-side in your browser — nothing you generate is ever transmitted anywhere.
