Doesn't work for me either.

In London and cannot sign in.

It is not working for me either. It appears that it does not recognize my username and/or password, despite the fact that it is saved and that I have been using the same one for years.

Just had the same problem and had a mini heart attack - thought my account got compromised and all my points gone. Good to know it's a Marriott problem. :p

Now when I log in, it prepends rewards@ to my user name. Still not working.

Same thing in SF

Looks like Marriott has taken the whole thing down for some work. When I try to log in now, there is a "Sorry but we are working on the site" message that pops up.

Hopefully, once they finish, everything will be back in working order.

Still a problem here.

I try signing in as CPRich (not my real ID) and it comes back with "invalid user or password" and rewards@CPRich pre-filled in the user name field.

Annoying

Back Up!

Again when I am trying to make reservations for my upcoming trip I cannot log in. It just throws me back to the log in screen.

Anyone else having problems today? I keep getting "Invalid user name and/or password (7)." and I've changed my password twice!

Yup...same problem.

Same exact thing here, was worried for a second my account was compromised, but looks like I'm not alone.

Just called Marriott. They are having problems with the sign-in page today.

I called (Ritz) about 1.5 hours ago... 0 ETA... apparently everyones login isn't working. Sadly that was after resetting my password 1/2 a dozen times to no avail.
