How to enable 2FA on Principal

← Principal overview Supported

Principal 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 Principal account.

Step-by-step setup

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

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