The FormsAuthenticationCredentials class provides a way to programmatically access and modify the credentials element of a forms section in the authentication section of the configuration file. This type is part of a group that includes the FormsAuthenticationConfiguration, the FormsAuthenticationUserCollection, and the FormsAuthenticationUser types. With the exception of the collection type, all the others directly affect the underlying configuration tags.
The FormsAuthenticationCredentials can write information into the related section of the configuration file according to the restrictions defined by MachineToApplication. Any attempt to write in a configuration file at a level not allowed in the hierarchy will result in an error message generated by the parser. However, you can use this class to read configuration information at any level in the hierarchy. For safety and scalability, it is recommended that you use an external repository, such as a database, to keep the users' credentials.
This example demonstrates how to specify values declaratively for several attributes of the credentials section, which can also be accessed as members of the FormsAuthenticationCredentials class.
The following configuration file example shows how to specify values declaratively for the credentials section.
<credentials passwordFormat="SHA1"> <user name="aspnetuser1" password="5BAA61E4C9B93F3F0682250B6CF8331B7EE68FD8"/> <user name="aspnetuser2" password="E38AD214943DAAD1D64C102FAEC29DE4AFE9DA3D"/> </credentials>
If you use the credentials section, be sure to follow the guidelines explained at ASP.NET Authentication. For scalability and better security, it is recommended that you use an external database to store the users' credentials.

The following code example demonstrates how to use the FormsAuthenticationCredentials class.
// Get the Web application configuration. System.Configuration.Configuration configuration = WebConfigurationManager.OpenWebConfiguration("/aspnetTest"); // Get the authentication section. AuthenticationSection authenticationSection = (AuthenticationSection)configuration.GetSection( "system.web/authentication"); // Get the forms credentials collection . FormsAuthenticationCredentials formsAuthenticationCredentials = authenticationSection.Forms.Credentials;
