HI I would like to ask something.  I was wanting to now something.  A little while back I could not get back into my facebook account.  So I had to get a code from security@facebookmail.com.  What I want to now since Iam back into my free facebook profile for a while now.  When I go into password and security to change my password I get the message saying you can't make this change at the moment.  What does this mean when can I change my password for my facebook account.  What I do not understand is this what does it mean when we have noticed another device.  After a while of using this device then you will be able to change your password.  How long will it be until I can change my facebook password here is a screenshot below:

Thanks.

No I did not receive any responses or asked to reply to them.  I just wanted to make sure this email was safe or not save I just don't want somebody bad to get a hold of my private information. Thanks for the reply.
