How to enable 2FA on 20i

← 20i overview Supported

20i 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 20i account.

Step-by-step setup

1
Sign in to 20i and open your 20i 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 20i 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 20i account.
5
Save your backup codes.
Store the recovery codes 20i gives you somewhere safe — you'll need them if you lose your phone.

Menu names on 20i can change — the official 20i 2FA documentation ↗ always has the exact, current path.
