# web.xml Visual Editor: Login Configuration

Element | Description
--- | ---
None | No authentication, this is the equivalent of removing the login configuration element from the deployment descriptor.
Digest | An authentication mechanism in which a Web application authenticates itself to a Web server by sending the server a message digest along with its HTTP request message. The digest is computed by employing a one-way hash algorithm to a concatenation of the HTTP request message and the password of the client. The digest is typically much smaller than the HTTP request and does not contain the password.
Client Certificate | An authentication mechanism that uses HTTP over SSL, in which the server and, optionally, the client authenticate each other with a public key certificate that conforms to a standard that is defined by X.509 Public Key Infrastructure.
Basic | You can type the name of the security realm in the Realm Name field. There is no validation for this value.
