          Access tokens used to access protected GitHub, GitLab, or
          other locations requiring token-based authentication.

          Access tokens are specified as a string made up of
          space-separated `host=token` values.  The specific token
          used is selected by matching the `host` portion against the
          "host" specification of the input. The actual use of the
          `token` value is determined by the type of resource being
          accessed:

          * Github: the token value is the OAUTH-TOKEN string obtained
            as the Personal Access Token from the Github server (see
            https://docs.github.com/en/developers/apps/building-oauth-apps/authorizing-oauth-apps).

          * Gitlab: the token value is either the OAuth2 token or the
            Personal Access Token (these are different types tokens
            for gitlab, see
            https://docs.gitlab.com/12.10/ee/api/README.html#authentication).
            The `token` value should be `type:tokenstring` where
            `type` is either `OAuth2` or `PAT` to indicate which type
            of token is being specified.

          Example `~/.config/nix/nix.conf`:

          ```
          access-tokens = github.com=23ac...b289 gitlab.mycompany.com=PAT:A123Bp_Cd..EfG gitlab.com=OAuth2:1jklw3jk
          ```

          Example `~/code/flake.nix`:

          ```nix
          input.foo = {
            type = "gitlab";
            host = "gitlab.mycompany.com";
            owner = "mycompany";
            repo = "pro";
          };
          ```

          This example specifies three tokens, one each for accessing
          github.com, gitlab.mycompany.com, and gitlab.com.

          The `input.foo` uses the "gitlab" fetcher, which might
          requires specifying the token type along with the token
          value.

          If enabled (the default), Nix will consider tarballs from
          GitHub and similar Git forges to be locked if a Git revision
          is specified,

          This requires Nix to trust that the provider will return the
          correct contents for the specified Git revision.

          If disabled, such tarballs are only considered locked if a
          `narHash` attribute is specified,
          e.g. `github:NixOS/patchelf/7c2f768bf9601268a4e71c2ebe91e2011918a70f?narHash=sha256-PPXqKY2hJng4DBVE0I4xshv/vGLUskL7jl53roB8UdU%3D`.
