Verification verifies identity by sending a code in a text message to a mobile phone. That code is then either captured automatically or is entered manually by the user into a sign-up or login field to access an account.
When it comes to two-factor authentication (2FA), SMS has one main advantage over authenticator apps – market penetration. 2FA codes sent via SMS can be received on any SMS enabled handset, but authenticator apps need a smartphone to work.
By using an additional layer of security (a second factor), customers can be protected from fraudulent attempts to access their online accounts. When customers trying to log-in to an account need to provide further proof of ID in addition to a password, things can get a bit more difficult for people trying to access accounts unlawfully. Someone may have figured out your password, but do they have the mobile phone that the PIN number will be texted to, or the ID card to swipe and complete the second factor required to gain access?
Two Factor authentication (2FA) is a great way to confirm user ID. There are so many scams and fraudulent attempts to access accounts these days that introducing a second factor to verify identity just makes sense.
2FA pairs something a user knows, with something they have – for example, a password with a mobile phone or a token, key fob or ID card. It’s the second layer of security that ensures the account is not being accessed fraudulently, if someone does not have the mobile phone that receives the one-time passcode via SMS then they should not be accessing the account and so will be denied.
Traditional SMS only focuses on delivery rates, whereas Sinch SMS Verification recognizes that receiving the correct OTP code back is equally important. Capturing this data via our reporting API provides real-time statistics that enable us to monitor and then push traffic through the most appropriate route to maximize speed – ensuring OTP codes are delivered as quickly as possible.
