Onboarding that Users Love & Trust

Building an onboarding flow that encourages users to sign up for your app can be challenging. Many people are cautious to give up their entire social history to an app they just downloaded, and email and password logins as a last resort are cumbersome.

With Digits, you can make your onboarding flow dead simple for your users by enabling them to login and signup using their phone number -- an identity that they already use everyday.

Onboarding that Users Love & Trust

Empower your users to sign up or sign in to your app in two simple steps.

Unlock Growth across the Globe

Phone numbers are the primary identity for the fastest growing mobile demographics, including emerging markets, which account for over 70% of the world's mobile population. With Digits, you can build a customized onboarding and sign-in experience for these markets.

Unlock Growth across the Globe

Tap into massive growth potential for your app with our phone verification in 191 countries and built-in support for 28 languages. Don't worry, we'll do the heavy-lifting for you.

Keep Your Team & Users Delighted

When users forget which service they used to sign up for your app -- email addresses, usernames, or passwords -- you can lose customers. By using our SMS verification in lieu of passwords, you can minimize both support costs and sign-in failures -- all while keeping your users happy and your app growing.

Easily authenticate users with Digits

Easily authenticate users with Digits and stop worrying about clunky captchas to keep out spammers. You'll have full control over the quality of your user base and give users the best in-app experience.

Build a trustworthy, effortless onboarding and sign in flow across all devices

Build a trustworthy, effortless onboarding and sign in flow across all devices -- mobile or Web. Enable users to sign up using Digits on your website so they can easily confirm their account with a simple code securely sent to their phone.

Dead Simple

In just a few lines of code, you can solve all your onboarding and authentication needs and focus on building amazing experiences for your users. Digits gives you the power to easily customize the colors and fonts of your onboarding flow -- so it feels completely native to your app.

Phone-based onboarding

Phone-based onboarding has been limited to large companies who can afford the time to build the infrastructure to deliver SMS -- until now. With Digits, you gain the same level of security and SMS capabilities by simply plugging into Twitter's own trusted, global infrastructure.
