My facebook page temporarily locked.?

[Black Cat]

I tried logging into facebook and this came up. What should I do?
"Someone recently tried to log into your account from an unrecognised device or location. Please verify if it was you who tried to log in."
It wasn't me who signed in, in a unrecognised device or location so am I being hacked?

There is a chanced you could have been hacked. Check your email to see if you got some thing from facebook to unlock it and check the time and place the person logged in on facebook when logging in. If it is an unfamiliar place then yes could have been someone else.

It's either someone tried to log in your acount or you, using other device that is not you usually used to log in. Just log in it, and you will see the location and type of device used. There is an option if it was you or not, you can reset your password. And that's all. And it's better to enable your log in notification so that you will receive a notification right after someone logged in to your account.
