Authenticator App - Novaz

Blockchain.com 2FA Setup with an Authenticator App

blockchain.com Supported

Blockchain.com 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 Blockchain.com account.

Crypto transactions can't be reversed, so protecting your Blockchain.com sign-in with 2FA is essential. Besides an authenticator app, Blockchain.com also offers SMS text codes and a hardware token. 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 Blockchain.com supports

  • SMS text message
  • Authenticator app (TOTP)
  • Hardware token

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

How to recover your Blockchain.com account

If you lose access to your authenticator and Blockchain.com 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 Blockchain.com doesn't, or you didn't save them, use Blockchain.com's account-recovery or support process (or ask your admin, for a work account) to get back in.
