Property Value

The password entered by the user. The default is nullNothingnullptra null reference (Nothing in Visual Basic).

Remarks

The Password property contains the password entered by the user. The password is in clear text. For more information, see Basic Security Practices for Web Applications.

Note:
If you manipulate the UserName or Password properties programmatically, it is important to do so at the correct time during the page life cycle. The values of UserName and Password are not available during the Page_Load phase, but are during the Pre_Render phase.

Login control properties represented by text boxes, such as UserName and Password, are accessible during all phases of the page life cycle. The control will pick up any changes made by the end user by means of the TextChanged event triggered by the textboxes.

Examples

The following code example passes the Password property to a custom authentication method.
