# Parameters of YouTrack as SAML 2.0 Identity Provider

To configure YouTrack as the Identity Provider for your service, you need to know certain parameters of your YouTrack server. You can find all the required parameters in the `SAML 2.0 > Settings` tab.

| Parameter | Description |
| --- | --- |
| Sign in URL | Identity Provider URL |
| Sign out URL | This is the URL to which the Service Provider sends the sign out request. Also, to this URL the Service Provider redirects your users after they sign out.  |
| Metadata URL | The SAML 2.0 metadata file contains information about YouTrack as the Identity Provider. |
| IdP entity ID | The `entityID` is the unique identifier of YouTrack as the Identity Provider.  |
| Default name ID |  `DefaultNameIDFormat` configuration parameter of a SAML federation: The format of the default `nameID` returned by YouTrack when a service provider requests an unspecified name identifier format.     In SAML, a service provider indicates the name identifier format it wants to receive from YouTrack. If the SP uses `unspecified` as the format for the nameID (`urn:oasis:names:tc:SAML:1.1:nameidformat:unspecified`) in the request to sign in to YouTrack, then YouTrack returns the nameID in the format defined by this parameter.      For the description of the standard name identifier formats, refer to the Section 8.3 of the [Assertions and                             Protocols for the OASIS SAML2.0 standard.](https://docs.oasis-open.org/security/saml/v2.0/saml-core-2.0-os.pdf)     |
| SSL Key | SSL Key to encrypt interaction between YouTrack and service providers. When the SSL Key is selected, the SHA-256, SHA-1 and MD-5 Fingerprints of the certificate packed into the key store are displayed.  |
