What an authorized user is and why you might add one
An authorized user on a T-Mobile account is someone you give permission to manage the account — make changes to the plan, add or remove lines, pay bills, or contact customer service on your behalf. You stay the account owner and remain responsible for all charges, but the authorized user can handle day-to-day tasks without needing your password.
People typically add authorized users when they want a spouse, adult child, or business manager to handle account details without sharing their login credentials. This keeps your password find while still letting someone you trust make necessary changes.
Key Takeaways
- You can add an authorized user through your T-Mobile account online, by calling customer service, or in a store, and the person does not need to be on your phone plan.
- The authorized user will receive a PIN or temporary password to access the account, and you can revoke their access at any time.
- An authorized user can manage the account but cannot change the account owner or remove themselves — only you can do that.
- T-Mobile does not charge a fee to add an authorized user, but the person you add should understand they will see your account details and billing information.
Adding an authorized user online through your T-Mobile account
Log into your T-Mobile account at t-mobile.com using your username and password. Once you are signed in, look for the account settings or profile section — this is usually found in a menu labeled "Account" or "Settings" at the top of the page.
Find the option for "Authorized Users" or "Account Managers" and select "Add Authorized User." You will be asked to enter the person's name, email address, and phone number. T-Mobile will send them an email with instructions to set up their access. They will need to create a PIN or password to log in, and they can then manage the account from their own login.
Keep the confirmation email T-Mobile sends you — it will show the authorized user's name and the date they were added. You may need this information later if you want to remove them or update their permissions.
Adding an authorized user by phone or in a store
Call T-Mobile customer service at 611 from your T-Mobile phone or 1-844-839-4534 from any phone. Tell the representative you want to add an authorized user and have ready the person's full name, email address, and phone number. The representative will process the request and send the authorized user an email with setup instructions.
You can also visit a T-Mobile store in person. Bring a photo ID and let the store associate know you want to add an authorized user. They will collect the same information and send the invitation to the person's email. This method is useful if you want to confirm the request when ready or if you have questions the representative can answer face-to-face.
What the authorized user can and cannot do
Once someone is set up as an authorized user, they can view your account balance, pay bills, add or remove phone lines, change your plan, upgrade devices, and contact T-Mobile customer service about your account. They can also see your billing history and account details.
However, an authorized user cannot change the account owner, remove themselves from the account, or access your T-Mobile ID password. Only you, as the account owner, can make those changes. This protects you from someone locking you out of your own account.
Removing an authorized user
If you no longer want someone to manage your account, log into your T-Mobile account online and go to the Authorized Users section. Find the person's name and select "Remove" or "Delete." Confirm the removal, and their access will end when ready.
You can also call T-Mobile customer service at 611 or 1-844-839-4534 and ask them to remove a specific authorized user by name. Have your account number ready. The representative will process the removal and send you a confirmation email.
Security considerations when adding an authorized user
Only add someone you trust completely, because an authorized user will see your full billing information, account balance, and phone numbers on your plan. They will also be able to make changes that affect your service and charges.
If you are concerned about security, you can add an authorized user with limited permissions — some accounts allow you to restrict what they can do. Ask T-Mobile customer service whether your account type supports permission levels. You should also change your own password after adding an authorized user, just as a precaution.
If an authorized user's email is compromised or they no longer need access, remove them right away. T-Mobile does not notify you when an authorized user logs in, so checking your account activity regularly is a good habit.
Frequently Asked Questions
Does the authorized user need to be on my T-Mobile phone plan?
No. An authorized user can be anyone — they do not need to have a T-Mobile line or be a family member. They just need an email address to receive the setup invitation.
Can I add more than one authorized user?
Yes. You can add multiple authorized users to the same account. Each one will have their own login and can manage the account independently. You can remove any of them at any time.
What happens if I forget to remove an authorized user?
They will keep their access until you remove them. There is no automatic expiration date. If you are concerned someone still has access, log into your account and check the Authorized Users section to see who is currently listed.
Can an authorized user change my password?
No. An authorized user cannot change your account password or your T-Mobile ID password. Only you can do that. This prevents them from locking you out of your own account.
Will the authorized user see my text messages or call history?
No. An authorized user can see account and billing information, but they cannot access your text messages, call logs, or personal data on your phone. Their access is limited to account management only.
