At its F8 developer conference, Facebook introduced Account Kit, a way for developers to create easy logins for their apps. Apps that use account kit can, unsurprisingly, allow users to login with their Facebook account, but they will also let you create an account using only your phone number or email address.

From Facebook:

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.

Developers will be able to create a custom user interface around Account Kit's functionality. They'll have access to the Basic UI option for easy and quick implementation, as well as the Advanced UI option for better customization.

Account kit will also provide detailed login analytics to help developers better understand their audiences. Users will also be able to choose to receive a Facebook notification with their login authentication rather than a text message.

Developers can get started with Account Kit right now.
