How to enable 2FA on Home Assistant

← Home Assistant overview Supported

Protect your Home Assistant 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 Home Assistant and open your Home Assistant 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 Home Assistant 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 Home Assistant account.
5
Save your backup codes.
Store the recovery codes Home Assistant gives you somewhere safe — you'll need them if you lose your phone.

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