Learn about secure mail keys and why you’ll need one to access your AT&T email from a desktop program or email app without Open Authentication (OAuth).
INSTRUCTIONS & INFOAT&T email app security to update soon
Act now to avoid email hiccups
Do you use a desktop program or a mobile app to access and manage your AT&T email? If so, we suggest you use one with Open Authentication (OAuth) technology, which encrypts your username and password. Learn about OAuth and find out if your app uses OAuth.
If your email program or app doesn’t have OAuth technology, it will only be able to access your AT&T email program or app using a 16-character secure mail key. Be sure to use myAT&T to create a secure mail key for each of your AT&T email addresses and subaccounts, so you can continue to:

Additional secure mail key notes
Learn how to switch to an OAuth email app and avoid secure mail keys
For step-by-step instructions to set up or update your email account in several popular email apps, use our Troubleshoot & Resolve Tool.
Review email apps on all your devices
Check the email apps you use on each of your devices to see if they use OAuth technology. If they don’t, we suggest you switch to an OAuth email app. Otherwise, you’ll have to set up a secure mail key to use with your non-OAuth email apps. Learn more about OAuth email apps
Get one secure mail key for each email address
Every AT&T email address, including each subaccount, must have its own secure mail key if you want to use it with an email app that isn’t OAuth compatible.
Access your AT&T email account without an OAuth mail app or secure mail key
You can always read and manage your email through a Web browser at currently.com. Use your AT&T email and password.
Remember that a secure mail key won’t affect your AT&T email password
You’ll still use the same password you currently use for your AT&T email account in OAuth-compatible apps, myAT&T, other AT&T products like currently.com and webmail. And, when you change your AT&T email password, you won’t need to get a new secure mail key.
Keep your secure mail key as long as you like
Secure mail keys never expire.
Create a new secure mail key for a blocked or locked account
For safety reasons, we delete secure mail keys whenever we have to lock or block your account. If that happens, you’ll have to create a new secure mail key for each AT&T email address.
Give your secure mail key a nickname
We suggest you create a nickname to identify your secure mail key, especially if you have more than one. It’s much easier to recognize a nickname, like Ari’s email or Kelly’s email, than the 16 random characters you entered when you set up your email.
