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;
    }
}

Private Sub CheckBox_Changed(sender As Object, e As RoutedEventArgs)
    If revealModeCheckBox.IsChecked = True Then
        passwordBox1.PasswordRevealMode = PasswordRevealMode.Visible
    Else
        passwordBox1.PasswordRevealMode = PasswordRevealMode.Hidden
    End If
End Sub

Remarks

PasswordRevealMode replaces IsPasswordRevealButtonEnabled to give you more options for how the user is able to view their password. The IsPasswordRevealButtonEnabled property is ignored.

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. Note that due to 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.

Note

Prior to Windows 10, the password reveal button was not shown by default. If the security of your app requires that the password is always obscured, be sure to set PasswordRevealMode to Hidden.

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.

In previous versions of Windows Phone, PasswordBox used a CheckBox to toggle whether the password was obscured. You can create a similar UI for your app, as shown in the example. You can also use other controls, like ToggleButton, to let the user switch modes.
