Applications:Oracle APEX & PL/SQL client
From Yubico
Oracle APEX & PL/SQL YubiKey integration by APEXtras
An Oracle PL/SQL package that includes functions to perform YubiKey verification against the Yubico public authentication service,
together with an APEX process that demonstrates integration of YubiKey verification with a custom APEX authentication scheme.
This enables an APEX application to use two-factor authentication based on username, password, and YubiKey OTP.
The YubiKey verification function is in a PL/SQL package and is not APEX-specific - it can be used to provide two-factor authentication to any Oracle process.
