Why do I keep having to change my Apple passwords i

You are sign in here .  .  .  with your Apple ID & Password.

Your Apple ID is the personal account you use with all Apple products and services. It includes the email address and password you use to sign in, as well as the contact, payment, and security details that you use with Apple.

You can’t merge multiple Apple ID accounts.

What happens when you use the same Apple ID that you use to sign in here?

• If you need help removing Activation Lock and have proof of purchase documentation, you can start an Activation Lock support request.

You have to show proof of ownership of your product, provide all documentation showing your purchase of the device.

If you do not have additional proof of ownership, contact the reseller. They may be able to provide the original purchase document.

Once Apple receive your proof of ownership, Apple will further review your request and provide an update.

This has also happened to me, with both of the last big iOS updates. Super frustrating to say the very least. And it’s beyond that, it’s an infinite loop. 2+ hrs with tech support both times, each time stating I had done something. But, I hadn’t and it was the day after software update both times. Makes me uneasy about security of my account honestly.

I had to change password and provide unlock pin for all devices. That is sus if you ask me. Not a fan.
