#### Precautions: 

* Some Android phones do not have Google play services installed, and you need to download the "Google Installer" to install Google Framework services.
* Google Dynamic Password requires the camera to be turned on, and authorization is required when opening the App. 
* Some mobile phones need to restart the phone when enabling Google play services. 
* After the two-step verification function is turned on, users need to enter a verification code when logging in, withdrawing assets, or generating a withdrawal address.

#### Common Problem

1. The Android phone prompts that Google Play needs to be opened in order to scan the QR code. What should I do if Google Play cannot be downloaded?
   * Some Android phones cannot enable Google Play services. Please use "Manually enter verification code" to manually enter the verification characters.
2. If the phone is lost, how to reset Google two-step verification?
   * If you have saved the sixteen-digit key for Google two-step verification, you can rebind it directly in Google Authenticator. If the sixteen-digit key is not saved, you can enter your email and password on the official website login page and click "Security verification is not available" to reset it. For details, refer to "How to Reset Google Two-Step Verification". Note: After the operation is successful, in order to ensure the security of the account, the currency withdrawal function of the account will be automatically frozen for 48 hours, and other functions will not be affected.
3. What should I do if Google two-step verification fails to bind?
   * Make sure you have Google Authenticator installed on your phone. 
   * Make sure the date and time on your phone and the computer running Binance are synchronized. 
   * Make sure you enter the correct login password and Google verification code on the binding page. 
   * If you cannot bind Google two-step verification, you can also bind mobile phone verification to protect your account.
