# Advanced installation

An advanced installation of OneSpan Authentication Server allows you to customize your installation and configuration in much greater detail than a basic installation. This installation option is best suited if you need complete control over software components to be installed, and the configuration to be completed.

> If you want a quick, default installation and configuration, perform a basic installation. For more information, see [Basic installation](/sec/docs/oas-iglnx-basic-installation-3-28).

> If you re-run the Configuration Wizard after the installation (from the Maintenance Wizard), the OneSpan Authentication Server daemon will be restarted.
