- [IRPCLogin.GetAuthenticationPlugins](https://developer.m-files.com/APIs/gRPC-API/Reference/MFiles.IRPCLogin/GetAuthenticationPlugins/index.md): Lists the authentication plug-ins installed on the server, without their configurations.
- [IRPCVaultAdmin.GetMigrantAuthenticationConfigurations](https://developer.m-files.com/APIs/gRPC-API/Reference/MFiles.IRPCVaultAdmin/GetMigrantAuthenticationConfigurations/index.md): Lists the authentication configurations of the vault that need to be migrated to the current format.

- [`ExtensionAuthenticationTarget.supported_plugins`](https://developer.m-files.com/APIs/gRPC-API/Reference/Messages/MFiles.ExtensionAuthenticationTarget/index.md#f-supported_plugins): The authentication methods the target accepts. The `name` of the chosen one goes to `ExtensionAuthenticationResponse.plugin_configuration`.
- [`GetAuthenticationPluginsResponse.plugins`](https://developer.m-files.com/APIs/gRPC-API/Reference/MFiles.IRPCLogin/GetAuthenticationPlugins/index.md#response): Receives the plugin information.
- [`GetAuthenticationConfigurationResponse.plugin_infos`](https://developer.m-files.com/APIs/gRPC-API/Reference/MFiles.IRPCLogin/GetAuthenticationConfiguration/index.md#response): The matching plug-in configurations. `system_configuration` holds the configuration scope (`Scope`) to send back in `PluginData.configuration_scope`; `plugin_configuration` holds the plug-in's client settings.
- [`GetMigrantAuthenticationConfigurationsResponse.plugin_infos`](https://developer.m-files.com/APIs/gRPC-API/Reference/MFiles.IRPCVaultAdmin/GetMigrantAuthenticationConfigurations/index.md#response): The authentication plugin information of each configuration, in the same order as `configurations`.
