Social media giant Facebook has introduced a new security feature that allows users to use physical 'security keys' to access their profiles.
Facebook is now compatible with security keys which will let a social media user make sure he has complete control of one's account.
The option is an alternative to the two-factor authentication solution it currently offers, whereby users receive security codes for login approvals via text messages, security engineer Brad Hill said in a Facebook Security note.
"You can register a physical security key to your account so that the next time you log in after enabling login approvals, you'll simply tap a small hardware device that goes in the USB drive of your computer.
"Security keys can be purchased through companies like Yubico, and the keys support the open Universal 2nd Factor (U2F) standard hosted by the FIDO Alliance," he wrote.
Currently, it is only available for Android devices, and users will have to use the login system through the mobile site rather than through the Facebook app. In addition, you must have the most recent versions of Google Authenticator and Chrome downloaded.
These keys can be used with Google, Dropbox and Salesforce too. The USB keys - which cost around 17 pounds on Amazon - allow you to log in by tapping the key after entering your password.
Facebook which has 1.79 billion users and according to some media reports, around 600,000 logins are hacked every day.
