Answer 1

If you are working with toggle switch then

private void toggleSwitch1_Toggled(object sender, EventArgs e)
{
    if (toggleSwitch1.IsOn)
    {
        string a= textBox2.Text;
        textBox2.PasswordChar = '\0';
    }
    else
    {
        textBox2.PasswordChar = '*';
    }
}

here '\0' will show to password filed to plain text
