Question 1

How does 2FA work?

Accepted Answer

Two-factor authentication adds a second proof of identity (a 6-digit code from your authenticator app) on top of your password. When you log in, the service asks for the time-based code from 2FAS Auth in addition to your password. Full explanation: https://2fas.com/support/2fa-knowledge/how-does-2fa-work/.

Question 2

Where does 2FAS store my tokens?

Accepted Answer

On your device. Tokens are encrypted locally; optional iCloud or Google Drive backups are end-to-end encrypted client-side before upload. See https://2fas.com/support/2fas-auth-security-privacy/where-do-you-store-the-tokens/.

Question 3

Is 2FAS Auth end-to-end encrypted?

Accepted Answer

Yes. Encryption is performed on-device and the keys never leave your device. Details: https://2fas.com/support/2fas-auth-security-privacy/is-2fas-end-to-end-encrypted/.

Question 4

How do I move tokens from Google Authenticator to 2FAS?

Accepted Answer

Open Google Authenticator → Transfer accounts → Export accounts, then scan the QR code with 2FAS Auth. Step-by-step: https://2fas.com/support/2fas-auth-mobile-app/how-to-move-transfer-tokens-codes-from-google-authenticator-to-2fas/.

Question 5

What is the Decryption Kit in 2FAS Pass?

Accepted Answer

The Decryption Kit is a recovery artifact for your 2FAS Pass vault — keep it offline, never share it. Combined with your Master Password it can restore your vault on a new device. See https://2fas.com/support/2fas-pass-security-privacy/what-is-the-decryption-kit/.

Question 6

Does 2FAS require an account?

Accepted Answer

No. Neither 2FAS Auth nor 2FAS Pass requires a 2FAS-hosted account. Backup and sync use your existing iCloud, Google Drive, or WebDAV — not a 2FAS server.
