Benefits of using T-Mobile ID

Use T-Mobile ID to self-service multiple accounts and lines, using just one email address. Your T-Mobile ID profile is intended to link the services that you use with T-Mobile, not just the lines on your account. To prevent permission level issues, don’t link multiple phone numbers from one account to the T-Mobile ID.

Watch: How to create your T-Mobile ID


Update your password

It's good practice to change account passwords every few months, and we require that you change your T-Mobile ID password once a year.

Password requirements

  • 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

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.

Forgot your password?

No worries! Select Forgot Password? on My, and follow the prompts to reset it.


Secure your account with two-step verification options

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

  • 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, call 1-800-937-8997 for authentication.
  • When Always Require 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.

Two step-verification options

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

  • Security questions: Allows you to set security questions to confirm your identity.
  • SMS: Allows you to confirm your identity by text message to your T-Mobile ID.
  • 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.


Update your account profile

Update your account profile, including name, email, password, two-step verification, and the phone numbers linked to your T-Mobile ID.


Link / unlink phone numbers from your T-Mobile ID

You can use the same T-Mobile ID to access multiple accounts and lines so that others can log in and manage your accounts if you choose. And, you can link a new number to an existing T-Mobile ID.

To prevent permission level issues, don’t link multiple phone numbers from one account to the T-Mobile ID.
