I did that in December 2022, and then set it up on a different Apple ID, with a simple password and PIN, so if the repair place wanted any of (Apple ID, password, PIN) I could go ahead and give it to them. After the repair I did another reset, and restored the latest backup from the original Apple ID.

Worked fine, except it is now very confused about my "Longest Move Streak" record in Apple Fitness. Here's what it has said at various times this year:

2023-02-04: "You earned this award for your longest daily Move streak. 39 days, ending on 2023-02-03. Your current streak is 1,368 days".

2023-02-21: "You earned this award for your longest daily Move streak. 41 days, ending on 2023-02-20. Your current streak is 1,385 days".

2023-09-24: "You earned this award for your longest daily Move streak. 37 days, ending on 2023-09-23. Your current streak is 1,600 days".

The current streak numbers are correct. The longest streak numbers are now nonsensical and inconsistent.
