Yubikey

A YubiKey is a small physical device that provides an extra layer of security for your online accounts. When you want to log in, you insert or tap the YubiKey, and it authenticates your identity with a unique code that’s difficult for hackers to replicate. This process, called two-factor authentication, makes it much harder for unauthorized users to access your accounts, even if they have your password. The YubiKey works across many services and devices, offering a simple yet powerful way to protect your digital information from cyber threats.
