I'm trying to connect to the API for which I need the TOTP. But in the Smart API Dashboard, when I click "Enable TOTP" and enter my login credentials, I get an error message "LoginbyPassword is not allowed. Please switch to Login by MPIN now." but I don't see any login by MPIN option.

Can you please guide me how can I generate TOTP for my account?

PS: I'm using PHP API and when I call the GenerateSession() method, I get an response data as follows "{"status":false,"message":"Invalid totp","errorcode":"AB1050","data":null}"
