Home Assistant 2FA Setup with an Authenticator App
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.
A Home Assistant account can control connected devices in your home, so 2FA keeps intruders out. Home Assistant secures sign-ins with an authenticator app — set it up once and you're protected on every login.

Save a way to recover your account.
If Home Assistant shows backup or recovery codes, store them somewhere safe, away from your phone. If it doesn't, check how Home Assistant recovers accounts (support, an admin, or another sign-in method) before you need it.
Menu names on Home Assistant can change — the official Home Assistant 2FA documentation ↗ always has the exact, current path.
How to recover your Home Assistant account
If you lose access to your authenticator and Home Assistant gave you backup or recovery codes when you turned on 2FA, sign in with one of them; keep them somewhere safe, away from your phone. Not every service issues codes. If Home Assistant doesn't, or you didn't save them, use Home Assistant's account-recovery or support process (or ask your admin, for a work account) to get back in.
