OTP is a 4-6 digit number or alphanumeric code having a single-use purpose for a specific session/authentication. Double-factor authentication, or even multi-factor authentication is rather common in today’s world. It adds an extra layer of protection and helps to avoid fraud and security theft.
SMS is the only method that is utilised for delivering verification codes because it is the most popular alternative available to all micro and large businesses worldwide.
OTP SMS services are critical for organisations to handle registrations, password changes, and a variety of other online activities. OTP is also useful for other transactional objectives. It includes establishing a customer’s identification, securely establishing a firm, and facilitating operational work with total safety.
The OTP SMS is delivered to the user’s phone, and the recipient enters it to authenticate his/her identity. It comes for a limited time and allows for a single login. This is important in lowering the chance of fraudulent login attempts and, as a result, the danger of data loss.
