Using OAuth or secure mail keys

Access AT&T email with an app that uses 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.

Device & operating system (OS)Apps and programs that use OAuth
iPhones & iPads running iOS 9.0 and above
  • Apple Mail
  • Outlook Mobile
  • Yahoo Mail app
Android devices running Lollipop/5.0 or above
  • Gmail 
  • Outlook Mobile 
  • Yahoo Mail app
Mac computer running OS 10.11/El Capitan or aboveApple Mail
PC running Windows 10Windows Mail
Email app not listed?
Here’s a quick way to find out if your email app uses OAuth. Start setting up a new email account in your app. Your app may offer you a list of email providers that includes Yahoo. If it does, your email app is OAuth compatible. Be sure to select Yahoo as your provider. You’re all set!

Non-OAuth compatible email apps
  • 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

We suggest you switch to an email app that has OAuth. Get step-by-step help setting up or updating your email account in several popular email apps, with our Troubleshoot & Resolve Tool.

Get email with an app and a secure mail key
If you prefer to use an email app that isn’t compatible with OAuth, you’ll have to create a special code called a secure mail key. You’ll use this secure mail key instead of your AT&T password when you set up an email app.

Check email at currently.com
You can always use your regular password to access your AT&T email at currently.com (formerly att.net) through a web browser.

Getting email on all devices

Multiple devices using different email apps
If you access your AT&T email on multiple email apps across several devices, you’ll have to check each email app you use on every device. For example, you may use Outlook Mail on a laptop, Gmail on a smartphone, and Apple Mail on a tablet. Each device must use either an OAuth app or your secure mail key.

Email aliases and disposable email addresses
You don’t need a secure mail key for an email alias or disposable email address that goes with your AT&T email account. That’s because alias and disposable email addresses use the same password as the main email address it’s tied to.

Note: If your email address ends with @yahoo.com, be sure to verify your account status with Yahoo.
