Yubico Authenticator

Store your unique credentials on a hardware-backed security key and take it wherever you go from mobile to desktop. No more storing sensitive secrets on your mobile phone, leaving your account vulnerable to takeovers. With the Yubico Authenticator you can raise the bar for security.
* The Yubico Authenticator will work with any USB, Lightning, or NFC-enabled YubiKeys.
* As iPads do not have NFC, they will only work through a Lightning or USB connection.
The Yubico Authenticator generates a code used to verify your identity as you are logging into various services. No connectivity needed!
