Google Auth Client for Samsung Gear, Android, Android Wear, Fitbit

The new app is recommended for newer Gear Watches such as: Gear S3, and Galaxy Watch.

Supported Devices

This application is to support legacy Gear devices only, and it’s not actively developed anymore.  It’s recommended for the following devices:

  • Gear Neo
  • Gear II
  • Gear S

You can use it with Gear S2, S3, and Galaxy Watch as well, but it’s not recommended, and some features like import accounts from an MP3 file might not work, because newer devices validate the format of MP3 file, and a text file with accounts will be rejected.

New Features

With the new Android GAC Services app release it’s possible to create MP3 init file easily. Navigate to Backup page and select “Legacy backup” menu or press MP3 button on the bottom. A file named gac-codes.mp3 will be created in Music directory. Use Samsung Android Gear app to transfer that file to your Gear device and then use “Init from file” menu in your Gear GAC app for importing all accounts from gac-codes.mp3 file.

GAC App Description

GAC is a Tizen Application for Gear wearable devices. It has been tested and can run on Gear, Gear 2, Neo, Gear S, Gear S.

It can be installed on any of the devices above through Gear App available for Android and iOS smartphones.

On Gear S2 you can toggle accounts while on an account page by rotating a bezel:

    • 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:
      Rant

  3. This seems to only support the “time based one time password” (TOTP). Google Authenticator works with both time based and counter based. I am looking for a counter based app for my S3 phone. Any chance you have support for this that I can’t find?

    • That’s correct. It currently supports TOTP only. I’ll consider counter, but tell me why. If you use a watch, it always has time. Having a watch that doesn’t have a correct time set, doesn’t make much sense. I’ve just checked stock Google Auth app and didn’t see a “counter” option there in settings. Can you please point me to the place where I can choose “counter” as an option? Thanks.

  4. The app to control the Galaxy Watch is now called Galaxy Wearable. But the text file gac-codes.mp3 it is not regognised as a valid MP3 file, so it doesn’t show up when you select “Init from File”.
    I had to buy Gear File Manager Pro to get the file to the Music folder on my Galaxy Watch.

    • Sorry for the inconvenience, but the MP3 file was meant for legacy devices like Gear Neo, Gear S, etc. For newer ones including Galaxy Watch you should use companion app for transferring accounts.
