Passwords are susceptible to hacking, phishing, and brute force attacks. With a YubiKey, you add an extra layer of security because access to an account can only be granted if both the password and physical key are present.
U
Protection against phishing.
A YubiKey prevents phishing attacks from being successful. Even if a hacker manages to figure out your password through phishing, they still need the physical YubiKey to access your account.
B
User-friendly and fast.
Instead of entering an SMS code or opening an app, all you have to do is plug the YubiKey into a USB port or tap it (on NFC models). This not only makes the process more secure, but also faster and easier.
I
Support for multiple protocols.
YubiKeys support various security protocols, including FIDO U2F, FIDO2, OTP (one-time password), and smart card functionality. This allows you to use the same key for different services and devices.
K
Little dependence on network connections.
Unlike apps such as Google Authenticator, which rely on a smartphone and a network connection, the YubiKey works offline. This makes it useful in situations without Internet access.
E
Physical property required.
Because you need the physical YubiKey to log in, it becomes virtually impossible for hackers who want to gain access from another location to do so without the key itself.
Y
Broad compatibility.
YubiKeys are supported by many platforms and services, such as Google, Facebook, Dropbox, Microsoft, and Linux, and can also be used for securing email and password managers.
