|

// Supported schemes are HTTP authentication, an API key (either as a header, a cookie parameter or as a query parameter),

||
// mutual TLS (use of a client certificate), OAuth2’s common flows (implicit, password, client credentials and

// authorization code) as defined in RFC6749 (https://www.rfc-editor.org/rfc/rfc6749), and OpenID Connect Discovery.

// Please note that as of 2020, the implicit flow is about to be deprecated by OAuth 2.0 Security Best Current Practice.

// Recommended for most use case is Authorization Code Grant flow with PKCE.
