Description
This is an alternative to 2FA stock Authenticator (GA), which is based on Time-based One Time Password (TOTP). It integrated well with Samsung's Gear Authenticator Client (GAC) app, which is available in Samsung's App Store since 2015. It has rich backup/restore capabilities, including local phone storage and Google Drive. The latter is very handy for syncing GA accounts on multiple Android devices.
The application can be started locally on Android or remotely from a Gear or Galaxy Watch device. Having a Gear device is not required though. To start it from your Gear device, select "Connect to Phone" menu in GAC application. After the Gear device is connected, many options are available for transferring data between devices. A new account can be created by scanning a QR bar code or by entering a secret manually.
After the QR code scanned or entered manually, you can either send it to Gear by tapping "Send to Gear" button or save it on your phone using "Save" button.
If "Overwrite" checkbox is checked, an existing account will be updated with a new secret or a new one will be created if an account with this name didn't exist.
Gear's GAC application should be in a waiting state to be able to receive any messages from the phone. It means that all communications with the phone are possible only after "Connect to Phone" menu is tapped in your Gear GAC app and while a connection dialog is open.
GA Accounts page shows all accounts created by GAC app and stored on the Android phone.
Tapping an account's name or token on the accounts page will open a zoomed view for a single account. A token in the zoomed view will be updated automatically when an old token is expired. Accounts can be scrolled on this page using left and right arrows.
Press an account editing button on the right to change a shared secret or an account name, or both.
By default accounts are sorted in alphabetical order. Long press an account name and drag it to a new place If you want to change the order.
Accounts can be saved to and restored from an unencrypted or encrypted backup file stored in a local phone's storage or on Google Drive. Encryption is based on a password provided by a user. Encrypted backup will be signed with an HMAC signature to make sure that a backup is not corrupted during a restore operation. Unencrypted and password-less backups are available as well, but not recommended.
This application serves ads, but only for those users who use it without a watch. Ads will not be served any more after at least one successful connection has been made from a watch.

Comments on 2FA Hub for Samsung Watches for Android
★★★★★cronack 1· Jun 3, 2019
Great work!!! Pros: -Works flawlessly so far. -CONTAINS ADS. This is important for a free 2FA app. Any no-ad, no-IAP auth app is certainly selling your data, reducing security + privacy. Haven't seen one yet, tho... Cons: -A couple typos on initial launch popup. -Gray-on-gray buttons are hard to see. -Aspect ratio locked to be slightly greater than my native ratio of 18.5:9 (on my Note 9). Meaning, app is very narrow. -Needs to rename button. A little rough UX, but works and seems trustworthy.

This app is a lifesaver for anyone with multiple 2FA logins. I can easily add them to my watch, access them on my phone and keep an encrypted backup in case I lose or change either. The developer is also responsive and helpful. Thanks for all your work on this!
★★★★★Pete Weinman· Jan 20, 2019
Works but I wish there was a fancier option like Google authenticator on Wear OS.
★★★★★Jonathan Segal· Feb 24, 2020
Had some install issues and the developer worked on helping me late on Saturday night and during Sunday morning. Nothing was too much trouble for them. Excellent support. The best. The issue was the time on my phone not the app. The app now works perfectly and as described.

Core part of my life. I have been using the app with my S3 for a year now and rely on it every day. Does what I require and support is excellent.

This is sketchy and would not trust my auth codes with it. Be careful folks
