[edgarrmondragon]

Feature scope

Taps (catalog, state, tests, etc.)

Description

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, and OpenID-Connect-Core. 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 cases is Authorization Code Grant flow with PKCE.
