The following cases require re-authentication through KakaoTalk:
- If you are automatically logged out because you have not accessed the Upbit app for more than 30 days
- If you are automatically logged out depending on network conditions
If you are automatically logged out, you can log in through [Enter the PIN password you set or use the registered biometric authentication information] - [Enter the authentication number received through KakaoTalk notification message].
※ Depending on the performance of the terminal being used, if biometric authentication login proceeds quickly without members being aware, an authentication number will be sent to KakaoTalk linked to the phone number registered in member information.
For the purpose of strengthening security, an authentication number is sent for additional verification. If you enter the KakaoTalk authentication number you received, you can log in and use Upbit services.
