My password wont be accepted in apple id how to make a rigth password in apple id

The password is incorrect. Remember these password need to be exact, capitalization is usually the culprit.

Next, you Apple ID may be different from the iTunes password.

You should be able to recover either through Apple support.

Your Apple ID password is for the internet. If the mini is a single user setup you shouldn't need a password unless you are altering something about the operating system. (It does happen)

Call the people who sold you the machine and ask them the password they used to set up the machine. You should have full control of your computer, not just user control!

Your question leaves a few details up in the air. Of course, the ID is important to provide security (yours) for purchases. If your "current password" is not being accepted, you need to work that out through Apple, an Apple Store, or Apple repair shop.

Can you log in from another PC and change profile settings?

Double check the email address that is displayed, sometimes this gets changed for one reason or another. Once you've ensured it is correct, log in to the Apple ID website:
Apple My Apple ID
This rules out login problems with the Apple ID its self.
If you successfully log in on the website Try going in to Settings > Facetime.
Tap your Apple ID & Sign Out.
Sign Back in & try again.
If it still doesn't work do a basic reset of the device.
Make sure it is not plugged in.
Hold the home button & power button at the same time until you see the Apple logo.
Try again.
