AT&T email is getting a security boost. Thus, you will need to update your email settings if you use Outlook, Windows Live Mail, or Mac Mail. You may find more information about the security upgrade here. When setting up or updating your AT&T email, create a secure mail key.

Using Separate Apps on Several Devices

You will have to check each email app on each device if you access your AT&T email using different client applications on numerous devices. For example, on a laptop, you can use Outlook Mail, while on a smartphone, you can use Gmail, and on a tablet, you can use Apple Mail. You must use either an OAuth app or your secure mail key on each device.

Aliases and Disposable Email Addresses

An email alias or disposable address linked to your AT&T account does not require a secure mail key because alias and disposable accounts utilize a password similar to the primary address.

Check email at currently.com

You can access your AT&T mailbox at currently.com, previously att.net, from a web browser using your regular password. Moreover, ensure that your Yahoo account status is up to date if your mail address ends in @yahoo.com.

POP3 vs. IMAP: What's The Difference
POP3 and IMAP are two different ways to set up a mail address in a client application.

Even though they both allow you to connect to the mail server and access your emails using a client application, they still differ in that IMAP stores messages on the server rather than on a local device like a computer. POP3 mail, on the other hand, will attempt to establish a connection and store messages locally, whether on your computer or mobile. att.net email login
