Sharing my IPad

An iPad is a single-user device.

Unlike other computers with which you may be familiar, that support multiple user profiles - other than “managed” educational environments, OS/iPadOS devices are not intended to be shared.

Be aware that if you sign-out of iCloud and other Apple services - and allow another user to sign-in - you’ll not be able to change back for 90-days.

So as to prevent account abuse, some critical Apple services will only allow one change of signed-in AppleID (on a device) in a 90-day period.

In conclusion, unless you fully understand and accept the implications, you would be well advised to reconsider any attempt to share your iPad with another user.

That is a terrible idea. An iOS device is not designed to support multiple users. The endless problems you will experience are too numerous to predict.
