Google has rolled out an updated Authenticator for Android, coming in with a new design and support for Android Wear, where users can now generate verification codes on compatible smartwatches.

Straight off the bat, Google has finally implemented its Material Design, describing the app's new look as "refreshed." The company also throws in a nice new icon for the Authenticator, making it feel right at home in a modern environment.

Meanwhile, two-factor authentication is considered as one of the most effective security measures to steer clear of unauthorized access.

"Most people only have one layer — their password — to protect their account. With 2-Step Verification, if a bad guy hacks through your password layer, he'll still need your phone or Security Key to get into your account," Google says, noting that it adds an "extra layer of security."

Google Authenticator is arguably at the top of the proverbial food chain not only because of its security features but also the convenience it brings to the table, allowing users to retrieve their second-factor code without taking out their smartphones.

"There's also support for Android Wear devices, so you'll be able to get verification codes from compatible devices, like your watch," Google says.

With the recent development, it's easy to say that Google has stayed faithful to the concept of wearable techs, as one of the biggest points to use a smartwatch is to reduce the need to take out smartphones.

Moving forward, developers will get a kick out of the update, as Google is giving them access to a preview of support for NFC Security Key. To test things out, developers will need updated versions of Chrome, Authenticator, a Security Key with NFC support and, of course, an Android device. The Security Key is based on FIDO's specifications.

Google Authenticator for Android is now up on the Play Store.
