To set up authentication:

1. Select an authentication method from the drop-down list:

   • Basic authentication: Authenticates your data source using a username and password
   • Forward OAuth identity: Forwards the OAuth access token and the OIDC ID token, if available, of the user querying to the data source
   • No authentication: No authentication is required to access the data source

2. For Basic authentication only: Enter the User and Password.

3. Optional: Complete the TLS settings for additional security methods.

   TLS Client Authentication

   Toggle on to use client authentication. When enabled, it adds the Server name, Client cert, and Client key fields. The client provides a certificate that is validated by the server to establish the client's trusted identity. The client key encrypts the data between client and server. These details are encrypted and stored in the Grafana database.

   Add self-signed certificate

   Activate this option to use a self-signed TLS certificate. You can add your own Certificate Authority (CA) certificate on top of one generated by the certificate authorities for additional security measure.

   Skip TLS certification validation

   When activated, it bypasses TLS certificate verification. Not recommended, unless absolutely necessary for testing.

4. Optional: Add HTTP Headers. You can pass along additional context and metadata data about the request and response. Select Add header to add Header and Value fields.

5. Select Save & test to preserve your changes.
