Account Kit helps you grow your app or website by giving people a choice to sign in with their phone number or email address without the need for a password. It's a complementary solution to Facebook Login and doesn't require people to have a Facebook account.

Here's an example of how Account Kit works:

Most people find remembering passwords difficult, so Account Kit gives people the option to log into new apps with just a few taps using only their phone number or email address. There's no need for a username and password. People can use Account Kit without sharing any information from their Facebook profile—they don't even need a Facebook account to use it. By removing these major barriers to entry, Account Kit helps you increase your sign-ups and expand your audience.

Account Kit is simple and quick to implement for both new and established apps, so you can focus on building your core product instead of creating a login system and handling password storage. Account Kit is built on Facebook's infrastructure—as technology, systems and devices change, we'll update Account Kit to help keep your app's on-boarding flow current. We support SMS login for over 230 countries and regions, in more than 40 languages. Your app can use Account Kit to send up to 100K confirmation SMS per month at no charge to you.

Account Kit has several advantages:

  • Customizable user interface (UI): You can adapt the look and feel of Account Kit to match your brand. You'll find two UI options in the Account Kit SDK: the basic UI is an easy solution with simple customization for the header, background, and button. The advanced UI gives you more customization options (see below for example).
  • Rich analytics: If you use Account Kit alongside App Events from the Facebook SDK, you can get rich, aggregated analytics to help you better understand your audience and their login preferences.
  • Facebook notification backup option: If a person chooses to sign into your app using their phone number, but doesn't receive an SMS, but does have a Facebook account, they can choose to receive a Facebook notification to complete the login process. We built this backup option to help increase your conversion rate by making sure people have more ways to log in if needed.

Here's an example of our sample app leveraging the advanced UI customization:

Whether your app is in its conceptual stages or already established, Account Kit can help you grow by giving people more ways to log in. Saavn, a music streaming app, saw over half a million registered phone number users and a 33% increase in daily new registrants within the first two months after integrating Account Kit phone number login.
