I have to give my Iphone to Apple assistence for changing the battery, and I'm having an attested multisig wallet on the iphone - which of course I wouldn't like lo lose. Of course I'd empty that address containing bytes, but how to avoid that some rogue Apple employee makes a backup of the wallet for himself? One solution seemed to backup the wallet and erase Obyte entirely, but after I've made the backup I didn't find any way to restore it since iphone cannot locate the file.
Is therefore the Obyte app for Iphone actually useless, since you'll have to delete it with all its addresses first time you need to change the phone's battery?
You can set the "Request password" from "Spending Restrictions" section on Settings screen, then they can clone your wallet, but they won't be able to do much with it.
Restoring the backup should be in the same places where making the backup is, in the app on Settings screen. Make sure you have the latest version because earlier iOS versions didn't have fully fleshed out backup system, but it should work on recent systems. Try to save the backup in folder that can be accessed.
Thanks. Since by now my phone is already in their hands, with just emptied wallets, would it work all the same if I'll password protect the wallet later, before loading it again with coins? Would a backup of an unprotected wallet stay unprotected? IE is the password protection local or dag stored, affecting that address wherever it is?
As for the backup, we are talking about Iphone, not Android, I'm not aware of any folder you can access on Iphone. Before giving an answer you should have tried it successfully yourself. I have tried it for almost an hour, without any success. So either there is a way - in which case I'd like to read a precise tutorial - or there is no way, in which case you'd better remove the backup function from the Ios wallet.
If somebody clones your unprotected wallet then it doesn't matter if you add password-protection later, they would already have the copy, which is not protected.
Don't know how iPhones work, I know it offers you to "Save to files" or share it to email or Cloud Drive or what not. If it doesn't have folder or directories, does it have different locations? Like Documents, Download and so on? Try to save it to Cloud Drive and see if you can restore it from there. Full backups are password protected so, it should be safe to send it outside of the device.
