Basic access authentication

In the context of an HTTP transaction, basic access authentication is a method for an HTTP user agent (e.g. a web browser) to provide a user name 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 user name and password joined by a single colon : . It was originally implemented by Ari Luotonen at CERN in 1993 and defined in the HTTP 1.0 specification in 1996. It is specified in from 2015, which obsoletes from 1999.

Most browsers allow users to specifically clear only credentials, though the option may be hard to find, and typically clears credentials for all visited sites. Brute forcing credentials is not actively prevented or detected (unless a server-side mechanism is used). WWW-Authenticate: Basic realm="User Visible Realm" The server may choose to include the charset parameter from : WWW-Authenticate: Basic realm="User Visible Realm", charset="UTF-8" This parameter indicates that the server expects the client to use UTF-8 for encoding username and password (see below). For example, if the browser uses Aladdin as the username and open sesame as the password, then the field's value is the Base64 encoding of Aladdin:open sesame, or QWxhZGRpbjpvcGVuIHNlc2FtZQ==. Then the Authorization header field will appear as: Authorization: Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ== 'Basic ' + base64.b64encode(f"{ }:{ }".encode()).decode() ==External links==
