How to enable 2FA on Backblaze

← Backblaze overview Supported

Protect your Backblaze account with two-factor authentication (2FA). Once enabled, signing in also requires a one-time code from your authenticator app — not just your password.

Step-by-step setup

1
Sign in to Backblaze and open your Backblaze 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 Backblaze 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 Backblaze account.
5
Save your backup codes.
Store the recovery codes Backblaze gives you somewhere safe — you'll need them if you lose your phone.

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