Someone tried changing my password

[PoppyRos]

I woke up this morning to a text message verification code and an email confirming my password at 3am while I was sleeping. I then attempted to log in and I couldn't I tried resetting my password with my security questions didn't  let me in. Luckily I hadn't been kicked out of my email just yet so I received a reset password email during my attempts. I reset my password and changed my security questions is there anything else I can do/need to do like reporting a password change not done by myself?

@PoppyRos  Choose a very strong password, something like a quote or a line from a personal favourite song is what I tend to use. 

Fortunately as you have 2 factor verification on they did not get in.
