At today's Facebook F8 developer congress, the company introduced the Account Kit, a new universal connectivity system that can work through a non-password phone. 
Facebook's new Account Kit will let developers create products where users can only register with their phone number without requiring passwords, and the developer needs to write the code that manages all entries and sequences of connection operations.
All this will be done through a dedicated SDK, which developers will need to integrate into their services (on websites or applications).
Users will be able to sign in simply by typing their phone number on a page or an application that uses the Account Kit to receive an SMS with the password. So the user creates his account without needing to give a password that he should remember.
Facebook claims to support SMS connectivity in over 230 countries and in 40 different languages.
To make the new feature even more appealing, Facebook has announced that every 100.000 developer has free SMS confirmation messages a month.
Let's also mention that the new Account Kit is not limited to users who have a Facebook account.
The new service has already been tested on different websites, offered to help with testing the beta SDK.
