You have to change your pw every 30 days and never repeat a pw. If it closed you may need to go down there and sit to talk someone.
I arrived on a Monday just after lunch and although there were about 10 people waiting in front of me I was done and out of there before @2 PM. Like others said you'll probably have to visit in person if you can't login. If you can login I also found the new chat feature quite helpful
Unfortunately, you must arrive at 7:30am, so you won't be there all day.
