How do I disable the Apple ID sign in when logging into my Mac?
You could try this to disassociate your Apple ID password from login:

To Stop Using an iCloud Password to Login to a Mac:

Go to the  Menu and choose System Preferences (alternatively use LaunchPad or Spotlight to search for System Preferences
Choose Users &amp; Groups and select the primary Mac login that you want to disassociate the iCloud password and for which you wish to use a unique separate password
Click the Change Password... button next to the user name
At the prompt &quot;Do you want to change your iCloud password, or stop using your iCloud password to unlock this Mac and create a separate password?&quot; – choose &quot;Use Separate Password…&quot;
Set and confirm the new password and close out of System Preferences when finished

Now when the user is logging into macOS, a separate account password will be used rather than the iCloud and Apple ID account password. This setting is specific to individual user accounts.
