A Secure SMS Verification Solution Using Plivo’s SMS APIs

Confide's off-the-record professional communication app is makes it virtually impossible for users to capture and share sensitive information. To add another layer of security, Confide needed to implement a two-step SMS verification process, which is both convenient for the user and secure enough to confirm someone’s identify without compromises.
