If you want to turn on two-step authentication (2FA) to ensure login and withdrawal security, please refer to the following steps.
1. Go to "Security" and select "Authenticator".
2. Enter the verification code you received on your phone and click "Confirm".
3. Launch the authenticator app, enter the verification code, and click "Enable".
Note: It is strongly recommended that you back up the authenticator code securely so that it can be used in case of loss of the phone or other factors.
4. After activation is completed, you will see a "Current" tag next to "Authenticator".
Note: The above steps only enable 2FA for withdrawals. To enable 2FA during login, please use the slider shown in the figure below.
