Account security

T-Mobile offers multiple options for account security to keep your account secure by adding an extra layer of protection for your online login.


It's good practice to change account passwords every few months. T-Mobile will require that you change your T-Mobile ID password if we detect that this password was used on compromised websites not related to T-Mobile.

The password requirements are:

  • Must be between 8-50 characters
  • Must include at least 1 number
  • Must include at least 1 letter
  • Can't contain spaces
  • Can include these special characters: ~ @ # $ % ^ & * () / : ; ? , . <> !
  • Must be different from your last five passwords

To update or reset your password:

  • When prompted to change your password, update the password so that you don't get locked out of your account.
  • If your phone has a compatible biometric scanner (such as Touch ID or Face ID), you can use it on the T-Mobile app so you can sign in securely without having to remember your password.
  • For enhanced account security, the Primary Account Holder will receive two messages when changing the password. These messages will be sent to verify if you indeed submitted the request for a password reset.

Forgot your password? No worries! Select Forgot Password? from your T-Mobile account, and follow the prompts to reset it.

Two-step verification

  • Two-step verification requires you to pass an additional verification step when signing into your account.
  • There is a 24-hour delay between changing your two-step verification settings, and those settings becoming active. During that delay, Contact Usfor authentication.
  • When Always Required is set to ON, you'll be required to complete a second verification method every time you log in.
    • This requires two-step verification setup.
    • T-Mobile reserves the right to initiate two-step authentication at any time to keep your account secure.
  • As part of the 2nd-step of verification after password entry, our network will securely authenticate your phone number and Device/SIM registered on the network automatically.
    • If you are not using your own phone on our network, or using another device, a 6-digit verification code will be sent to your mobile number for verification.
    • Google Authenticator users will be presented with the option to use a 6-digit verification code, or Google Authenticator, if the network was not able to automatically verify your phone number.

After setting up the two-step verification during registration, you can also use these options to authenticate:

  • Security questions: Allows you to answer security questions to confirm your identity.
  • SMS: Allows you to confirm your identity by text message to your T-Mobile phone number.
  • Fingerprint or FaceID for two-step verification if you have the T-Mobile app installed.
  • Google Authenticator
    • Google Authenticator app, available to Android 2.1 and iOS 3G and newer devices, required as a part of a two-step verification set-up.
    • To disable this option, select No thanks.
    • Once Google Authenticator is set up on your T-Mobile ID, you can complete two-step verification using the Google Authenticator app instead of SMS, Fingerprint, or FaceID.
