Battle.net has details on a new version of Blizzard's mobile authenticator, the app designed to help keep user accounts secure. In the past users had to retype a code from the app into Battle.net to log-in, but the new version offers one-touch authentication within the app. Here's word on how this works:

Whenever* a log in attempt occurs on your account you will be notified via the app and prompted to Approve or Deny the request. You can also approve log in requests with notifications on your mobile or smartwatch without even opening the app! We hope this will help ease the log in process for those of you that already have an authenticator and encourage those of you who don’t to give it a try. You can find out more about authenticators on our Battle.net Authenticator FAQ.

The Mobile Authenticator with the new One-Button feature is available now on iOS® and Android™.

*Please note that by default you will only need to approve a log in attempt once a week per device. You can change this setting on your Battle.net Account Management page.
