Auto SavedFrequently 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.
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.
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.
