US Mobile 2FA: How to Set Up an Authenticator App
US Mobile lets you secure your account with an authenticator app. With 2FA on, each login needs a fresh 6-digit code, keeping your US Mobile account safe even if your password leaks.
A US Mobile account can control services and connected devices, so protect it with 2FA. Besides an authenticator app, US Mobile also offers SMS text codes and email codes. 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.

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