Learn how to set up your T-Mobile ID login and password so you can log in to My T-Mobile, your one-stop-shop for managing your account.


What's in it for me?

A T-Mobile ID is your key to keeping your account up-to-date and secure, and even getting help from other customers. Here are a few of the great things you can do with your T-Mobile ID.

  • Pay your bill, set up a payment arrangement, or make an equipment plan installment.
  • Change the personal information on your account.
  • Protect your account by setting up a two-step verification security option.
  • Link a T-Mobile ID for multiple accounts.
  • Use your T-Mobile ID to participate in the T-Mobile Support community.​
  • And so much more.
Create your T-Mobile ID

Important: If you had a T-Mobile account that was canceled, and you want to reuse the email from that account, contact us so we can set that up for you.

T-Mobile app

  1. Open the T-Mobile app.
  2. On the Welcome screen, tap Get a T-Mobile ID.
  3. Enter your registration information and tap Sign me up.
  4. Enter the code from the text message we sent to your mobile device and tap Next.
  5. Follow the on-screen steps to complete your registration.

My T-Mobile (postpaid and prepaid)

  1. Go to My T-Mobile and click SIGN UP.
  2. Enter your information and click Sign me up.
    • Email verification steps: 6-digit verification code sent to your email address given during activation. Alternatively, you can send the code to a different email address.
    • Phone verification steps: 6-digit verification code sent to your mobile number. Selecting Send to a different number will register the number the code is sent to and not the number that started the registration process.
    • Account PIN verification steps: Use the account PIN/Passcode set up during activation. If you skip this step on a prepaid account, you won't have access to your account.
  3. Click Next, then follow the on-screen steps to complete the registration.
Update or reset 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.

  • When prompted to change your password on My T-Mobile or the app, 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! Click Forgot Password? on My T-Mobile.com, and follow the prompts to reset it.

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
Secure your account with two-step verification options

Two-step verification helps 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 in to 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.

  • Security Questions: They are uniquely individual knowledge-based questions and answers that have personal meaning and may include specific spellings or be case sensitive.
  • Google Authenticator: Requires the Google Authenticator app as a part of a two-step verification set-up. The Google Authenticator app is available to Android 2.1 and iOS 3G and newer devices. Set up Google Authenticator on your T-Mobile ID if your using a device that supports two-step verification using SMS. If you have the T-Mobile app, you can also use Fingerprint or FaceID for two-step verification. 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.
  • Always Require: when ON, you'll be required to complete a second verification method every time you log in. This requires two-step verification setup.



Change 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 or 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.
