A More Secure SMS OTP Alternative: Instant Link™
Instant Link is a second-factor authentication (a.k.a, a “proof of possession check”) service that allows companies to embed a secure clickable link in an SMS text. Essentially, Instant Link looks similar to an SMS OTP at first glance and works in a similar way, but instead of a numerical passcode that can be intercepted, a secure link is sent via SMS that can be clicked by your customer to authenticate them and perform a secure “cryptographic handshake” confirming that it’s really your customer on the other end of a transaction.
