A one-time password (OTP) is an automatically generated numeric or alphanumeric string of characters. It is used to authenticate and verify users before a transaction or a session in an app/website. Used by businesses to ensure a secure user flow, an OTP SMS service provider ensures timely delivery of these messages.
