Let’s look at why SMS two-factor authentication is the safe, straightforward method to use, and how implementation can be easier than ever with this free WordPress two-factor authentication plugin.
Today’s consumers demand beefed-up security from the sites they interact with. Data theft and credit card fraud frequently make the headlines, as hackers are getting savvier at cracking passwords. It’s clear that one method of authentication – a password for example – is not enough. You may add a second layer of protection through your payment gateway, using an authentication service such as Verify by Visa. Or you could implement your own extra barrier of security.
SMS two-factor authentication is a popular method as it works with a user’s mobile phone – something they always have on them. Typically, a user receives a randomly generated four or six-digit one-time PIN (OTP), which they then enter on the web page they are trying to access. SMS is not dependent on having internet access, and works on any phone and in any language. It’s also easy to work out your messaging budget with something like Clickatell’s bulk SMS pricing estimator.
Let’s look at a few typical scenarios:
First-time registration: When a user registers with a site for the first time, they could choose to authenticate themselves via SMS OTP to ensure that it is actually them signing in.
Adding a credit card: If you are offering the convenience of storing credit card details, you could secure this function with two-factor authentication.
Using loyalty points: If your ecommerce website has a loyalty point system – or accepts loyalty points as payment – a secondary mode of authentication should be required. After all, spending points is just like spending money.
Activating a one-click payment: Shopping with just one click is a great time-saving feature for regular shoppers, yet it should still be verified with a method of two-factor authentication such as an SMS OTP.
