# Licensing

Each OneSpan Authentication Server instance will require a license key to be loaded into its server record, even if you are using an evaluation license. If this is not completed during the installation process, it will need to be done before OneSpan Authentication Server can be used for authentication or signature validation.

Additionally, you may need to upload license keys for specific client components to work properly.

For more information, refer to the OneSpan Authentication Server Administrator Guide.
