Featured YubiKeyAuth 1.1.0

Provides strong 1FA/2FA authentication with one-time passwords (OTPs), using YubiKey USB token.


This plugin provides strong 1FA/2FA authentication with one-time passwords (OTPs), using YubiKey USB token. It make use of Yubico's Web service (YubiCloud) for verifying OTPs in the i-MSCP authentication process.

The one-time password requirement is enabled on a per user basis, and one user can associate one or many YubiKeys to his i-MSCP account, according the administrator setup.

Usage of a YubiKey in i-MSCP authentication process is either mandatory or optional, depending on the administrator setup. When it is optional, a user that has not associated a YubiKey to his account can simply ignore the YubiKey OTP input field.
