If the user chooses to log in with OTP, they will need to enter the mobile number or email address they used to sign up. Once they have entered this information, the system will send an OTP to the mobile number (even if the user entered an email address, the OTP will still be sent to the mobile number). Once the OTP has been entered, the user will need to click the verify button, and they will be logged in to the fancall application.
