Since 2017, Facebook allows you to use a hardware security key for two-factor authentication on the desktop. On mobile, however, securing your account means relying on either an authenticator app or an SMS code. This is changing today, with the possibility of using a security key available on the desktop, Android and iOS.
Security keys are small devices the size of a USB flash drive that you typically connect directly to your computer or mobile device to authenticate your identity with an online service or application. Since a hacker should get the key from you physically, they are considered to be one of the most secure ways to protect your data online. And most companies recommend that people who are frequently targets of hackers, including politicians and activists, use them. A company called Yubico makes it for both iPhones and Android devices. Google has its own line as well as.
Once you have a passkey, setting up Facebook to use it is easy. Just head to the Security and connection from the settings menu. Remember, you are not buying a new device to secure your online accounts. By simply enabling two-factor authentication, you take an important step towards your online protection.
