We highly recommend all coins.co.th users to enable two-factor authentication on their account.
If you did not enable two-factor authentication, you will have to verify your account with an SMS or email token once per browser to keep your account more secure.
Upon signing in, you will be asked to fill in the six-digit password sent to your mobile phone via SMS. After you have entered the password, click 'Verify' to proceed with the login.
If you have a difficulty in receiving the six-digit password via SMS, you can choose to receive the password via email by clicking 'Get a new code via email.'.
