يوبيكي 5 سي

The YubiKey 5Ci has six distinct applications, which are all independent of each other and can be used simultaneously. Note: Some software such as GPG can lock the CCID USB interface, preventing another software from accessing applications that use that mode.

Interface

The YubiKey 5Ci uses a USB 2.0 interface. All of the applications are available through this interface.

Applications

FIDO2

The FIDO2 application allows for secure single and multi-factor authentication, and can store up to 25 resident credentials. These credentials, which are protected by a PIN, enable passwordless login, where the YubiKey, unlocked by a PIN and authorized by touch, can log you in to your accounts without entering a username or password. The FIDO2 application is FIDO certified.

USB Interface: FIDO
