The risk on mobile devices like ipads is that they can get stolen.
And once they’re stolen, anything stored on them belongs to who has your device.
I’m just an amateur but I can collect all stored usernames and passwords from a stolen ipad in less than 5 minutes. Do NOT store any passwords or identifying data on your ipad, or any other mobile device for that matter.
Treat them like your wallet, if you lose them or they get stolen, what have you lost
I recently attended a security conference and watched a demo of hackers recovering all personal and cached data from an ipad. Their summary comment was
‘If you care about it, do not access it from your ipad and do not store it on your ipad.’
That’s not anti-apple, it’s anti-mobile.
