Something is happening with Apple ID this weekend. As reported by , Apple users started complaining online last night about being signed out of their Apple IDs on all their devices without explanation.

Engadget has reached out to Apple for more information.

Apple hasn’t said anything publicly about what’s going on, and its System Status page hasn’t mentioned any problems with Apple ID or other systems in the past 24 hours.
