  Yubikey Neo and Yubikey 4 are both hardware security keys designed to protect digital assets. However, there are some differences in their security features. Yubikey Neo supports NFC (Near Field Communication) technology, which allows you to authenticate with your device by simply tapping it against an NFC-enabled device. On the other hand, Yubikey 4 does not have NFC support. Both keys offer strong two-factor authentication and support various protocols like OTP (One-Time Password), U2F (Universal 2nd Factor), and PIV (Personal Identity Verification). However, Yubikey 4 has a higher memory capacity compared to Yubikey Neo, allowing for more applications and credentials to be stored on the key. Overall, both keys provide robust security features, but the choice between Yubikey Neo and Yubikey 4 depends on your specific needs and preferences.
