Wearable security: Two-factor authentication apps for Apple Watch
The Apple Watch could become our central hub in a wheel of identity, in which all spokes rotate around our wrist. Some early Watch apps already have a high degree of utility. But we’re only scratching the surface of what’s to come.
In this roundup, we look at six apps that offer varying forms of authentication on the Watch. Three allow a tap on the Watch to unlock something: an account, a login, a computer, or more. The other three handle the most common form of app-generated second-factor authentication codes.
Speak, Friend, and enter
As a highly personal device, the Watch should let you chain its security with that of your phone: the default configuration locks a Watch when it’s removed from your wrist, and unlocks it when your phone is unlocked. To use these apps, you’ll always have to have your phone with you, and you’ll have to unlock one or both devices to use them.
