I sort of did that at my first web-job. I thought it was a bit unhandy that the customers had to be mailed a link to the admin interface, why not just put a link to the login on the front page? A couple of days later I learned why. There's always a good reason somewhere, you just don't know why yet. The reason? Well, the admin interface was written in ASP. According to the guy that called me in panic said that ASP version was so very old it was extremely insecure. I didn't have access to the database so could not verify anything but the webserver logs had a lot of "Bobby tables" in them so I have a strong suspicion it wasn't all ASP's fault... Anyway, we ended up with the database disappearing in the night or containing random data until I got that phonecall asking why we were linking directly to the admin interface :-) They were very good at restoring the database though, just took an hour or so every morning until they found the reason.
