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

• 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? from your T-Mobile account, and follow the prompts to reset it.

• 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 Us for 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.

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.
