Basic
Basic authentication is available on all server types.
Basic is the typical authentication scheme for web applications. A user accessing an application page is prompted for a username and password. With basic, the password is obfuscated but not encrypted.
Basic can be used with internal security, LDAP, and SAML as authorization schemes.
Note
Since the browser does not provide a way to clear a user’s authentication information in basic, basic-digest, or digest, the user remains logged in until the browser is shut down. In addition, there is no way to create a custom login page using these schemes. For certain deployments, application-level authentication may be more appropriate.
