One time passwords are the passwords that that send us when we try to login or register and we need to verify our email if and phone number.

They are a means to authenticate that we are the correct user of that particular account or service. This is a very secure method to authenticate the user as the mobile will be present to the correct person only and each tie there is a new code which is send and the code is 4-6 digits long.
