EASY TO USE

Experience it for yourself

Digits sends users an SMS confirmation code, which they enter into your app to confirm their identity - you can authenticate users in two steps! If the code doesn't arrive quickly, built-in voice fall-back comes to the rescue. See how it works by typing in your phone number.

“Onboarding and verifying new users is refreshingly simple, and has helped us achieve extraordinary growth especially in the developing world.”

Kayvon Beykpour, CEO/Co-Founder

“With Digits, we can now expand more quickly across the globe while focusing on building the content of our app!”

Ryan Johnson, VP of Mobile Engineering

“With Digits' customizable SMS, our brand is represented in every touch point to our users, building trust and keeping our conversion rates high!”

Jonas Drüppel, Co-founder
