2-Factor OTP SMS

Two-factor authentication is a method of identity verification using two different factors; any combination of knowledge, possession or inherent factors. Two-factor authentication is a subset of multi-factor authentication, which uses a combination of multiple factors for verifying or authenticating user identity. In a typical Two-factor setup, it requires a temporary code generated and sent to the user’s phone in addition to a password that is required for login. Adding an extra layer of SMS-based verification process to your login is certainly better than relying on a password alone. Muthofun offers a secure API to facilitate 2F authentication for any online application. Our secure API can seamlessly integrate into any application to make it more secure in real-time.

2 Factor SMS authentication service configured on transactional SMS channel which works 24X7 and OTP SMS can be delivered on DND mobile numbers as well. 2-Factor authentication SMS can be pushed through a dedicated pipe based on the requirement, and delivery of such messages is ensured through fail-over routing. Our 2 Factor voice SMS authentication service (launching soon) is also a good alternative when multiple failed attempts are made for delivering OTP SMS. Voice OTP can also go along with SMS OTP service to give your user a better choice based on his need. Due to peak load during business hours, when SMS OTP may face some latency, Voice OTP is a good alternative.
