Dear all,
If you have changed cellphone or your google auth is lost, then you can find back your google auth key with the following step:
1. Login your catex account, if you have enabled Google Auth for login, then you will be redirected to the following page:
Click the "Google Auth Lost" link. and submit the info required, then Google auth will be sent to your email
2. If you did not enable Google Auth for login, after login your account, just access the following link:
After you input your email, the google auth key will be sent to your email, then in your new cellphone, you need to input the google auth key manually instead of scan QR code.
Thanks
