Hello,
Do you have any other administrators? If so maybe they reset it. Have you ever have former administrators who are no longer administrators? If so, it is possible if you do not have it set to re-confirm login details via the security setting(s) (located in ACP-->General-->Security) then if you had a forum administrator, who no longer is one, just a regular member, if that person still has the exact link to your acp, they could still access it. I learned this a few years ago when I had slight dispute with a friend of mine over acp stuff, I removed him and he could still access my acp through the link (he even showed me) and from then I always had it checked to re-confirm login details, that way no who truly is not an admin, can not get into the acp. If such (the above case I mentioned) is the case for you, that can be why your banner was changed. You should tick that security setting. You can also check recent administration actions the adminsitration log.
WHATEVER YOU DO THOUGH, DO NOT GIVE THEM YOUR LOGIN DETAILS.
