GAC - 2FA TOTP Auth Client

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.

这是2FA stock Authenticator（GA）的替代方案，它基于基于时间的一次性密码（TOTP）。它与三星的Gear Authenticator Client（GAC）应用程序很好地集成，该应用程序自2015年起在三星的App Store中提供。它具有丰富的备份/恢复功能，包括本地手机存储和Google Drive。后者非常便于在多个Android设备上同步GA帐户。

该应用程序可以在Android本地启动，也可以从Gear或Galaxy Watch设备远程启动。但是不需要齿轮装置。要从Gear设备启动它，请在GAC应用程序中选择“连接到电话”菜单。连接Gear设备后，可以使用许多选项在设备之间传输数据。可以通过扫描QR条形码或手动输入密码来创建新帐户。

扫描或手动输入QR码后，您可以通过点击“发送到齿轮”按钮将其发送到Gear，或使用“保存”按钮将其保存在手机上。

如果选中“覆盖”复选框，则将使用新密码更新现有帐户，或者如果不存在具有此名称的帐户，则将创建新帐户。

Gear的GAC应用程序应处于等待状态，以便能够从手机接收任何消息。这意味着只有在Gear GAC应用程序中点击“连接到电话”菜单并且连接对话框打开时，才能与电话进行所有通信。

GA帐户页面显示由GAC应用程序创建并存储在Android手机上的所有帐户。

点击帐户页面上的帐户名称或令牌将打开单个帐户的缩放视图。当旧令牌过期时，缩放视图中的令牌将自动更新。可以使用向左和向右箭头在此页面上滚动帐户。

按右侧的帐户编辑按钮可更改共享密钥或帐户名称，或同时更改两者。

默认情况下，帐户按字母顺序排序。长按帐户名称并将其拖动到新位置如果要更改订单。

帐户可以保存到本地电话存储或Google云端硬盘中存储的未加密或加密的备份文件中并从中恢复。加密基于用户提供的密码。加密备份将使用HMAC签名进行签名，以确保在还原操作期间备份不会损坏。也可以使用未加密和无密码的备份，但不建议这样做。

此应用程序提供广告，但仅适用于没有手表使用广告的用户。在与手表成功建立至少一个连接后，将不再提供广告。
