@DoleeYang@mastodon.socialHow can UserDefaults, which is only readable/writable by the app itself, be used for fingerprint?
Apps being sold and bought?
@DoleeYang I’m curious as well. Could it be app groups? But that’s limited to a specific set of apps from the same company 
@DoleeYang If you ever dump all properties of UserDefaults, you'll see that the system puts a lot of values in there, which you have access to. E.g. which keyboards are installed.
No idea, why its all in there…
