Examples

This example shows how to use a CheckBox to let a user switch the reveal mode of a PasswordBox.

<StackPanel Width="200">
    <PasswordBox Name="passwordBox1" 
                 PasswordRevealMode="Hidden"/>
    <CheckBox Name="revealModeCheckBox" Content="Show password"
              IsChecked="False" 
              Checked="CheckBox_Changed" Unchecked="CheckBox_Changed"/>
</StackPanel>

private void CheckBox_Changed(object sender, RoutedEventArgs e)
{
    if (revealModeCheckBox.IsChecked == true)
    {
        passwordBox1.PasswordRevealMode = PasswordRevealMode.Visible;
    }
    else
    {
        passwordBox1.PasswordRevealMode = PasswordRevealMode.Hidden;
    }
}

Remarks

To change the character used to obscure the password, set the PasswordChar property.

Peek mode

By default, the password reveal button (or "peek" button) is shown. The user must continuously press the button to view the password, so that a high level of security is maintained.

The value of this property is not the only factor that determines whether a password reveal button is visible to the user. Other factors include whether the control is displayed above a minimum width, whether the PasswordBox has focus, and whether the text entry field contains at least one character. For security reasons the password reveal button is shown only when the PasswordBox receives focus for the first time and a character is entered. If the PasswordBox loses focus and then regains focus, the reveal button is not shown again unless the password is cleared and character entry starts over.

Hidden and Visible modes

The other PasswordRevealMode enumeration values, Hidden and Visible, hide the password reveal button and let you programmatically manage whether the password is obscured.

To always obscure the password, set PasswordRevealMode to Hidden. Unless you need the password to be always obscured, you can provide a custom UI to let the user toggle the PasswordRevealMode between Hidden and Visible. See the Examples section to see how to use a CheckBox to toggle whether or not the password is obscured. You can also use other controls, like ToggleButton, to let the user switch modes.
