• A method for an HTTP user agent (e.g., a web browser) to provide a user and password when making a request. In basic HTTP authentication, a request contains a header field in the form of Authorization: Basic <credentials>, where “credentials” is the Base64 encoding of ID and password joined by a single colon (“:”). Basic access authentication is specified in RFC 7617 from 2015, which obsoletes RFC 2617 from 1999. ← Wikipedia
