Can I block my iPad from accessing my Apple ID?

My daughter has my Ipad at another location and someone has attempted to change my apple ID password. I have since found out that someone has hacked her FB Messenger. I don't know if they have access to my device as well.

First and foremost, an iPad (and iPhone) are single user devices - that should not be shared with others. This ensures that your personal information and sensitive data is not accessible to others.

If your AppleID account or credentials have been compromised, your first priority and most urgent priority is to secure your account:

If you think your Apple ID has been compromised - Apple Support

Next, consider that any account passwords that you have saved on the device that is beyond your control may also have been compromised. Be especially mindful of financial (e.g. bank) passwords and account details.

If the iPad is not within your control, consider taking action as through the device was lost or stolen. Secure the device using Apple’s Find My services:

If your iPhone, iPad or iPod touch is lost or stolen – Apple Support

Use the Find My app to locate a lost or stolen device – Apple Support

You can sign out of it, I suppose, but it's not clear what you are actually trying to accomplish. Can you provide more detail?
