U2F (Universal 2nd Factor)

U2F (Universal 2nd Factor) is a security standard that adds an extra layer of protection to online accounts. When you log in, it requires a physical device, like a security key, in addition to your password. This device, often a small USB or NFC-enabled key, generates a unique code that confirms it's really you. Even if someone steals your password, they cannot access your account without the physical security key, making it much harder for hackers to breach your accounts. U2F provides strong, easy-to-use two-factor authentication to improve online security.
