How to enable 2FA on Blockchain.com

← Blockchain.com overview 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.

Step-by-step setup

1
Sign in to Blockchain.com and open your Blockchain.com account security settings.
2
Turn on two-factor authentication and choose the authenticator-app option.
Look for "Authenticator app", "Authentication app", or "TOTP" rather than SMS.
3
Scan the QR code with MS Authenticator App.
Open MS Authenticator App, tap add, and point your camera at the QR code Blockchain.com displays. Can't scan? Enter the setup key manually instead.
4
Enter the 6-digit code to confirm.
Type the code MS Authenticator App generates to verify and link your Blockchain.com account.
5
Save your backup codes.
Store the recovery codes Blockchain.com gives you somewhere safe — you'll need them if you lose your phone.

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