When you sign in into your account it asks for a username and password, this is the first verification process. Two-factor authentication adds another security layer after this to confirm your identity. It (2FA) could be a pin, a password, a one time password, a physical device, or biometric. It should be something only you have to know. Two-factor authentication is very important as a password isn’t as protective as we believe. Cyber attackers can test billions of password combinations in a second.
Two-factor authentication or two-step verification adds another layer of protection besides a password, and it is hard for cybercriminals to get this second factor and reduces their chance to succeed. Now Google is offering these 2FA authentication keys, and you can register for these on macOS devices using Safari (v. 13.0.4 and up), and Android devices running Android 7.0 “N” and up, using the Google Chrome web browser (version 70 and up). Users can register these independently or with those who have signed up for the Advanced Protection Program. It’s available for all users given you’re using the mentioned version of the software.
What is Security Keys?
Security Keys are the most secure form of two-factor authentication (2FA) or two-step verification to protect against various threats like hacking and phishing. Users are provided with physical keys that they can insert into the USB port of their device, when required the user will touch the key. On Android devices, the user will have to tap the key on their NFC ( Near Field Communication) enabled device. Android users can also opt for USB and Bluetooth keys. Apple mobile users will be provided Bluetooth-enabled security keys.
