Can Touch ID be diabled on Mac Air M

You should use the same AppleID account for both your Mac and your iPad (and iPhone if you have one). Each device can be configured with a different Passcode; some Users choose to set the same Passcode, others prefer to use differing Passcodes.

For iOS/iPadOD devices, a passcode is essential; if a Passcode is not set, much of the advanced functionality simply won’t work. The Passcode secures the Secure Enclave (this being the iPad security chip), within which the system encryption keys are stored. No Passcode = No encryption keys.

TouchID os entirely optional. If not configured, you can simply use the device Passcode - but perhaps consider that using TouchID actually simplifies use of the iPad.

Whatever you choose to do, perhaps consider review of the iPad User Guide - this being a rich (and frequently overlooked) source of information. The Guide is available both online using a web browser (such as Safari), or as an Apple Books download:

The Tips App, installed by default on all new models of iPad, provides a brief introduction - and leads you to the User Guide. In case you missed it, here is a link to the Tips App:

You can disable Touch ID on a Mac, as follows:

• System Preferences > Touch ID
• Deselect all of the check boxes on the resultant window.

Your Mac will now rely on using a password for authentication.
