Google 推出了一项全新的自拍影片登入功能，作为帐户恢复的额外选项。当使用者遗失装置且无法使用通行密钥时，这项功能可以像备用钥匙一样，帮助使用者重新取得 Google 帐户的存取权限。

这项功能的设定过程非常简单，只需不到五分钟即可在「安全性与登入」设定中完成。系统会要求在标准光线下拍摄且画面中只有使用者的脸部，并透过活体检测等工具来防止深度伪造攻击。（关键数字：less than five minutes）

这项登入选项是需要使用者主动选择加入的，并且必须在帐户被锁定之前完成设定。使用者在设定时，也可以自由决定是否同意让 Google 使用其自拍影片的资料来训练脸部辨识模型。

Google has introduced a new selfie video sign-in feature as an additional option for account recovery. When a user loses their device and cannot access their passkey, this feature acts like a spare key to help them regain access to their Google account.

The setup process for this feature is very simple and takes less than five minutes in the Security and sign-in settings. The system requires standard lighting with only the user's face in the frame, and it uses tools like liveness detection to prevent deepfake attacks.

This sign-in option is an opt-in feature and must be set up before the account gets locked out. During setup, users can also freely decide whether to allow Google to use their selfie video data to train facial recognition models.
