    • It is. Go to “Gear->Galaxy Apps” and search for “Client for Google Authenticator”. It’s available for many Gear models: Gear 2, Gear 2 Neo, Gear S, Gear S2, and Gear S3. What is your model?
      Finding GAC in Gear App

    • @ruky – what I’ve posted is a screenshot of a Gear app on my Android (Galaxy 6) device:
      1. Install the Gear app on your mobile device
      2. Make sure that your Gear device is connected to your mobile device
      3. Open Gear app and select “Galaxy Apps”
      4. Search “Client for Google Authenticator”
      5. Install it on your Gear device

      What Gear model do you have?

  1. Done,
    It works like a charm.
    However, I have to mention that the configuration is kindda tricky, even more adding the changes to the google interface. But it works

    • I know, config is tricky, but using MP3 approach should not be that bad. I wish Google to release an interface for getting a shared secret directly from the mobile app, but they don’t have any incentives to do that.

      Thanks for using.

  2. Just Updated the OS on my Gear, and this has stopped working – revolving blue/white cricle when I open it. Any suggestions as to what me be wrong?

    • Thanks for using. Unfortunately, it’s a common problem during the OS upgrade. It deletes the database and the only way to restore it is to re-install the application again. It’s not only happen to my app, but to others as well, e.g. check this rant:
