Online authentication

Online authentication occurs when a user authenticates to Windows via Digipass Authentication for Windows Logon, and the client computer can establish a connection to OneSpan Authentication Server via the network. OneSpan Authentication Server performs authentication in real time.

The user ID, password (optional), and OTP are sent to OneSpan Authentication Server for verification.

If the OTP credentials are valid, Digipass Authentication for Windows Logon receives the static Windows user password from OneSpan Authentication Server and uses it to authenticate to Windows.

If offline authentication is enabled, OneSpan Authentication Server also sends (encrypted) offline authentication data to Digipass Authentication for Windows Logon. Offline authentication data is used for offline authentication when no connection to OneSpan Authentication Server can be established.

Digipass Authentication for Windows Logon and OneSpan Authentication Server communicate via SOAP and through HTTPS.
