Hello @momma52,
I can understand the importance of being able to get into your myAT&T Account. I would be happy to assist you.
We have an informative page which gives step-by-step instructions on how to create an AT&T access ID. From this page is also a link which has instructions on how to manage secondary online access for your accounts.
If you have forgotten your ID or password please go here. For the ID you will be asked to enter the email you used and will be emailed further instructions.
If you need any further assistance, please let us know by replying in this thread. I hope you have an amazing weekend!
Jessica, AT&T Community Specialist
