I did this to briefly show the password (I am pretty new at coding so feedback welcome if this is a bad practise)

 private void buttonShowPassword_MouseDown(object sender, MouseEventArgs e)
    {
        TextBoxPassword.Properties.PasswordChar =(char)0;
    }

    private void buttonShowPassword_MouseUp(object sender, MouseEventArgs e)
    {
        TextBoxPassword.Properties.PasswordChar = '*';
    }

Just set the property to '\0' (which is the default value) to not mask characters.

Source: http://msdn.microsoft.com/en-us/library/system.windows.forms.textbox.passwordchar.aspx

Note: notice that '\0' is different from '0'. The first one is the null character, white '0' is the character that will be displayed as 0.

One of the easiest method to show and hide password is by using radio button inside password text box

The properties of radio button should be like:

this.radioBtn_ShowHidePassword.AutoCheck = false;

then the clicking activity has to be taken care manually just making it to be reverse of present state in its "Click" event

private void radioBtn_ShowHidePassword_Click(object sender, EventArgs e)
{
 radioBtn_ShowHidePassword.Checked = (! radioBtn_ShowHidePassword.Checked);
}

then finally the easiest way of show and hide password 

private void radioBtn_ShowHidePassword_CheckedChanged(object sender, EventArgs e)
{
   txtBoxPassword.PasswordChar = radioBtn_ShowHidePassword.Checked ? '\0' : '*';
   // here we can even include the code for changing the default picture of button to two different
   //representation like closed eye and opened eye which resembles Windows login
}

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

The VB.Net version is

Private Sub checkBoxShowPassword_CheckedChanged(sender As Object, e As System.EventArgs) Handles checkBoxShowPassword.CheckedChanged
    textBoxPassword.PasswordChar = If(checkBoxShowPassword.Checked, ControlChars.NullChar, "*"C)
End Sub

or

Private Sub CheckBox1_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CheckBox1.CheckedChanged
    If CheckBox1.Checked Then
        Me.txt_password.PasswordChar = "*"c
    Else
        Me.txt_password.PasswordChar = ControlChars.NullChar
    End If
End Sub

txtPassword is the Password textbox, chkSeePassword is the Show password checkbox. Now add some code to the checkbox's CheckedChanged event

private void chkSeePassword_CheckedChanged(object sender, EventArgs e)
{
        txtPassword.UseSystemPasswordChar = !chkSeePassword.Checked;
}
