123 Reg 2FA: How to Set Up an Authenticator App
Protect your 123 Reg account with two-factor authentication (2FA). Once enabled, signing in also requires a one-time code from your authenticator app — not just your password.
Whoever controls your 123 Reg account controls your domains, so 2FA keeps them from being stolen. Besides an authenticator app, 123 Reg also offers SMS text codes and security keys. An authenticator app (TOTP) is usually the best balance of security and convenience — and it's safer than SMS codes, which can be intercepted through SIM-swap attacks. For the strongest protection, 123 Reg also supports hardware security keys.

How to recover your 123 Reg account
If you lose access to your authenticator and 123 Reg 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 123 Reg doesn't, or you didn't save them, use 123 Reg's account-recovery or support process (or ask your admin, for a work account) to get back in.
