If you’re like most people, you have email apps that let you read and manage email on your computer and mobile devices. For your security, we suggest you only use email apps with an email technology known as Open Authentication or OAuth. OAuth encrypts your username and password to protect your info from hackers and fraudsters.
If you are using Outlook, or any other desktop program / email app that is not currently compatible with Open Authentication (OAuth), you will need to create a Secure Mail Key.
Soon you’ll have to use either OAuth or a Secure Mail Key to get your email through an app. But, don't worry! This page will help point you to all you need to ensure your service is not interrupted.
We are implementing a more secure way for customers using mail clients to login to their AT&T mail service.
If you use a mail client like Thunderbird, Gmail or Outlook to access your mail on your mobile device or computer, you may need to update your settings.
We want to make sure you don’t lose access to your AT&T email. Here’s how to update your email app settings to meet our security standard:
