If it is your first login attempt, kindly wait for some time as the delay can be due to network congestion. Try logging in again or try restarting your device. The first OTP is sent to your mobile to verify your mobile number. Make sure you are getting enough signals on your phone
Note - OTPs will be only sent to your mobile number for security reasons. CoinDCX doesn’t send OTPs on emails or other mediums.
We strongly recommend to Bind Google 2 Factor Authentication to avoid network delays in the OTP delivery and also further secure your account.
If none of the above steps work, please contact customer support.
