You can use the CreateUserWizard.PasswordHintText property to provide guidelines and requirements for the user on how to create a password. For example, you could set the CreateUserWizard.PasswordHintText property to "Your password must be at least six characters long." You can then use the CreateUserWizard.PasswordRegularExpression property to validate that the user entered a password that conforms to the guidelines.

The value of this property, when set, can be saved automatically to a resource file by using a designer tool. For more information, see System.ComponentModel.LocalizableAttribute and ASP.NET Globalization and Localization.
