A one-time password (OTP) is an automatically generated number with length of 4 or 8. It is used to authenticate and verify users identity before signup or during transaction in an app/website. Used by businesses to ensure a secure user flow, an OTP SMS service provider Tiniyo ensures timely delivery of these messages.
