Greetings @airtas!
Thank you for letting us assist you. It will be a pleasure to clear up any questions you may have.
If you do not want to give another person any access to your account you certainly do not have to. They can make a payment over the phone, without any information about the account except phone number. This method will require you to tell them the amount the payment should be, but they will not have access to any of your account’s information.
Another great option will be to have them go into a store and use the payment terminals. This will not disclose any information, while still accomplishing your goal. You can find a store near you using our fast and easy online Store Locator. All you need to do is enter your zip code, and you can find any stores near you.
I hope you found this advantageous! I hope this helps answer any questions, and please have a great rest of your evening!
Jordan, AT&T Community Specialist
