Bithumb 2FA: How to Set Up an Authenticator App

bithumb.com Supported

Bithumb supports app-based two-factor authentication (2FA). Turning it on adds a second layer of protection, so a stolen password alone can't unlock your Bithumb account.

Crypto transactions can't be reversed, so protecting your Bithumb sign-in with 2FA is essential. Besides an authenticator app, Bithumb also offers SMS text codes. An authenticator app (TOTP) is usually the best balance of security and convenience — and it's safer than SMS codes, which can be intercepted through SIM-swap attacks.

2FA methods Bithumb supports

  • SMS text message
  • Authenticator app (TOTP)
  1. 1

    Download Authenticator App - Novaz

    Install Authenticator App - Novaz from the App Store on your iPhone or iPad and open it — you'll use it to scan Bithumb's QR code and generate your 6-digit sign-in codes.

    Turn on two-factor authentication and choose the authenticator-app option.

  4. 4

    Scan the QR code with Authenticator App - Novaz.

    Open Authenticator App - Novaz, tap add, and point your camera at the QR code Bithumb displays. Can't scan? Enter the setup key manually instead.

    Enter the 6-digit code to confirm.

    Type the code Authenticator App - Novaz generates to verify and link your Bithumb account.

  6. 6

    Save a way to recover your account.

    If Bithumb shows backup or recovery codes, store them somewhere safe, away from your phone. If it doesn't, check how Bithumb recovers accounts (support, an admin, or another sign-in method) before you need it.

Menu names on Bithumb can change — the official Bithumb 2FA documentation ↗ always has the exact, current path.

How to recover your Bithumb account

If you lose access to your authenticator and Bithumb gave you backup or recovery codes when you turned on 2FA, sign in with one of them; keep them somewhere safe, away from your phone. Not every service issues codes. If Bithumb doesn't, or you didn't save them, use Bithumb's account-recovery or support process (or ask your admin, for a work account) to get back in.
