You get the OTP number which you have to enter the webpage. This is to make sure that you own the email address as you verify the OTP
To create a new password ( in case you forget your password)
Many times you forget the password of your email, bank account and many other things that you do online. There are many ways to setup a new password and the safest way is to use OTP. You get an OTP and when you verify that OTP, you get a link to change the password and then you can change your password.

1. First you will login to your account and then you will request fund transfer
2. After that the bank’s computer will create a code (ie one time password) and send it to the mobile number given in your bank. The bank’s computer knows which code it has sent to you.
3. Then you will get that code through SMS on your mobile
4. Then you will enter that code on the page of the bank website where there is a place to enter one time password (OTP).
5. Now the bank’s computer will check that you have entered the correct OTP or not
6. Once the bank’s computer has checked that OTP is correct, it will complete your fund transfer request.

Some we do not receive OTP – why ?
Many times we have seen that OTP is sent but OTP is not coming, then you check this
- Your phone’s network is coming or not – if the phone is not in network then SMS will not come and hence OTP will not come.
- Is your incoming (incoming) blocked ? If there is no balance in the phone then you face such problems
- Check that you have given the correct phone number.
- If all the above is correct, then the computer system from where the OTP is supposed to come is not working properly or is overloaded
- You test the “Resend OTP” option
- Many banks and other websites also offer “OTP on call”. Try it too.
- Many banks and other websites make you generate OTP by calling a number or sending a message from your registered mobile. So also check this option as well
