Frequently Asked Questions

Is this online 2FA tool safe to use?

Yes. 2FA.cheap is a 100% client-side application. The TOTP generation algorithm runs entirely inside your browser using JavaScript. We do not have a backend server, and your secret keys are never transmitted over the internet. You can even load this page and use it entirely offline.

What is a bulk 2FA authenticator?

A bulk 2FA authenticator allows you to paste multiple setup keys (Base32 secrets) at once. Our tool automatically cleans the input, extracts the keys, and generates real-time 6-digit verification codes for all of them simultaneously. This is incredibly useful for developers or users managing multiple accounts.

What format should my secret keys be in?

You can paste raw Base32 secret keys (e.g., JBSWY3DPEHPK3PXP), or formats like "username:secret". Our advanced regex engine will automatically ignore invalid characters and extract the valid 2FA secrets for you.
