Using Two Factor Authentication with SMS
Two Factor authentication or 2FA is easy to use with SMS (text messages). The theory behind 2FA is that 2 things have to be combined to authenticate someone’s identity. Something the customer knows i.e a password has to be combined with something they have i.e. a phone.
The overwhelming majority of people these days have a mobile phone that is capable of receiving SMS, and bearing in mind that mobile phones are rarely more than an arm’s length away, what better way to reach people in an immediate fashion. Sending a single use, time sensitive text message to confirm a customer’s identity could be the difference between someone’s account being compromised and remaining safe.
