Surfing the web, you log into your email account and someone may be able to get a hold of your username and password. However, if you had a YubiKey NEO, things wouldn't be so simple. After plugging your YubiKey NEO into your USB or tap your NFC mobile device, it will generate a 44 character OTP for your accounts. When you sign into your email it will now require an OTP generated by your YubiKey NEO.

Imagine that people were monitoring your network traffic without your consent. They may be able to glean your password by examining captured TCP packets, but the YubiKey NEO password they capture will be of no use to them, because it can be used only once! This two-factor authentication system provides you with the security you need to keep your information safe at all times. Check out a video of the YubiKey here.
