How two-factor authentication works to verify mobile users
SMS two-factor authentication (2FA) is one of the most effective ways to verify users; it can be easily added as an extra layer of security in business applications.
The user submits a request for verification, then your server makes contact with Messente’s API and transmits the user that requires 2FA verification.
The user receives a unique one-time verification code by text via Messente’s systems. This is sent and received more or less instantly.
Your server uses the API to send the inputted code back to Messente for verification. If it matches the original code, user verification is completed.
Is SMS two-factor authentication secure?
No security measure is 100% failsafe, and this applies to SMS 2FA too. App-based 2FA is more secure than SMS 2FA, but the latter is much better than having no authentication measures in place at all.
Not using 2FA is actually quite common - for instance, 90% of Gmail users don’t have 2FA set up. If you do use 2FA, this will make hacking into your systems more difficult.
What is an SMS OTP and how does it work?
OTP stands for one-time password. It’s a unique PIN code, generated by Messente’s Two-Factor Verification API and is sent to a user’s phone number, for them to input into your app or website. It’s time-sensitive, so if the code isn’t entered after a short amount of time, it expires, and can no longer be used. An SMS OTP just means that the PIN code is sent by text message.
Lots of businesses, including large enterprises like banks and financial services providers, use SMS OTPs to help prevent fraud and keep customer accounts secure.
