I just received an email for a weekend promotion with a link to Marriott. The link took me to Marriott to log in and when I attempted to it required me to change my password. I changed browsers and then computers to log in to my account and each time received the same message:
​​​​​​
Your immediate action is required.

In a continuing effort to safeguard your account, we are requiring you to change your password.

We recommend that you create a password that is unique to this site to help ensure the security of your account.

I called them and the agent was clueless and of course there is no website security department to talk to as they only have an email link and not a phone number. I did ask the agent to make sure my points were still there.

Anyone else having this issue?

edited to add that I received the same message on my phone so it must be legitimate.
