GAuth v2.0 now available in BlackBerry World. Two Step Google Authentication
Rapid Mike has just released his GAuth Application for BlackBerry 10 which allows you to use dedicated two-step authentication app built for Gmail.
From your 2-step authentication page, click on the set-up link for BlackBerry.
This will provide a code which you enter into Gauth to finalise authentication.
You’ll now be able to use Gauth to authorise new applications that make use of two-step authentication by using the one-time passcodes it generates.
Verification codes can also be sent via SMS to secondary numbers, or printed on a hard copy in case you lose your BlackBerry.
