This plugin displays text within your admin page's header to let the signed-on admin know when his/her password was last changed, giving them some amount of implicit warning as to the need to change their password. The display (as of v1.1.0) also includes the admin's previous login date and IP address from which the admin logged in.
Note: When an admin's password expires, s/he is instructed to enter their old/expired password and enter a new password.
