It can be annoying to set up two-factor authentication and boost the security of your accounts, but Google may have found a way to ease your pain. It's delivering an update to Authenticator for Android that not only touts a "refreshed" design, but receives codes from Android Wear smartwatches. You're no longer stuck using this solely on your phone. To top things off, Google is rolling in early support (sadly, developer-only) for the FIDO Alliance's NFC Security keys -- in the future, you may only need to tap devices together to sign in. If you can't bear the thought of logging in with a regular password, you'll want to grab this upgrade in short order.
