Enhancing the security of AT&T Mail...
Did AT&T send me an email or text about my email settings?
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.
What is Open Authentication (OAuth)?
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.
Learn about OAuth and find out if your app uses OAuth.
What is a Secure Mail Key?
If you are using:
- Outlook 2010, 2013, 2016, 2019
- Mozilla Thunderbird
- Windows Mail on personal computers running Windows 8 or older
- Apple Mail/Mac Mail on macOS 10.10/Yosemite or older
- Any other desktop program / email app that is not currently compatible with Open Authentication (OAuth)
A Secure Mail Key is a 16-character key that will allow these email programs or apps to access your AT&T email program or app.
Learn how to create a Secure Mail Key from your mobile device, tablet, or computer.
