Just In: Facebook Is Increasing Their Support for 2FA Security Keys On Mobile Devices


Facebook is actually increasing its support of physical security keys for two-factor authentication (2FA) on mobile devices,  the company added that.

The social platform has actually supported security keys for its desktop version since 2017, but beginning today, it will allow users on its iOS and Android apps to use them to secure their accounts as well.

Two-factor authentication gives another layer of support for online accounts, it’s requiring users to log in with their password and another additional piece of information, usually a numeric code generated by a third-party system.

If both pieces of information are not included, it’s much harder for someone to actually access your account even if they have your password.

“We strongly recommend that people consider using physical security keys to increase the security of their accounts, no matter what device they use,” Facebook’s blog post actually states.

Physical security including the ones that connect to your device using USB or Bluetooth is increasingly considered the best way to protect online accounts.

Other ways, like authenticator apps or SMS alerts, generate codes for users to type in, but these codes could potentially be intercepted by a desperate and manipulative third party seeking access.

Immediately this user connects the key which they need to keep on their person or nearby to their device, it verifies their identity, letting them log in.

Twitter added earlier this week it is planning a future update that will let accounts with 2FA enabled use security keys as their sole authentication method. Currently, Twitter users can use a security key plus a second 2FA method as a backup.
