How to enable 2FA on A2 Hosting

← A2 Hosting overview Supported

A2 Hosting 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 A2 Hosting account.

Step-by-step setup

1
Sign in to A2 Hosting and open your A2 Hosting 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 A2 Hosting 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 A2 Hosting account.
5
Save your backup codes.
Store the recovery codes A2 Hosting gives you somewhere safe — you'll need them if you lose your phone.

Menu names on A2 Hosting can change — the official A2 Hosting 2FA documentation ↗ always has the exact, current path.
