Facebook's Mobile App Gets Support for Physical Security Keys to Enable Two-Factor Authentication

Facebook is expanding support for the hardware security key to enable two-factor authentication on Android and iOS smartphones. Since 2017, Facebook allowed users to use a hardware security key for two-factor authentication on the desktop. In a blog post, the company states that physical security keys are small enough to fit on the keychain and can notify users each time when someone tries accessing the Facebook account from an unrecognised browser or mobile device. Notably, Facebook’s counterpart, Twitter recently announced that the social media platform would soon allow users to add an extra layer of security to their account with multiple security keys on both mobile and web clients.
