How to set up Google Authenticator (GA)?
Step1-Download Google Authenticator (GA) onto phone (iOS Users: Apple App Store /Android Users: Google Play).
Step2- Open the GA app on your mobile device, click the “+” icon and choose “Scan a barcode” or “Enter a provided key” to manually input the key words.
Step3- Scan the QR code displayed in the Security page of the Dcoin or manually enter the key shown in the figure below. At this time, the Google Authenticator app in your phone will generate a string of 6-digit verification codes, fill in the space, enter the Sign in password and click Confirm.
Step4- After you have successfully set up GA, a GA code (the 6-digit code) will be required for each login or security action. The code changes every 30 seconds. Please remember to only enter the newest code.
Step5- How to deal with the loss of mobile phone and Google verification code?
It is strongly recommended that you save the key or QR code when binding the Google verification code. In case of loss of the phone, you can rebind it on the new phone. If you forget to back up the key or QR code, please send the photo of the ID card and the contact phone to firstname.lastname@example.org to apply for unbinding the Google verification code. After the customer service personnel handle it, you can rebind the new Google verification code.
