Starting with version 2.22 privacyIDEA supports VASCO tokens.
VASCO OTP tokens are a proprietary OTP token. You can import the VASCO blobs from a CSV file or you the administrator can enroll a single VASCO token.
privacyIDEA uses a proprietary VASCO library vacman to verify the OTP values. Please note that you need to license this library from VASCO Data Security N.V. directly. The privacyIDEA project does not provide this library.
