If someone resets your appleid can they get into your iphone if they do not know the iphone password

No. All devices are promarily the same. In order to reset the phone, they have to know the password to get into it, and it usuallu also asks youre password again before it asks"do u want to reset". And even if they do reset ur phone, they wobt be able to see your info cuz they reset it. All ur info will be gone. But that does mean they can steal it and usevit themselves. One other thing, on a suprising percentage devices, if you turn the device ompletely off, (by holding the power button or taking out the battery and then putting it in again) then you hold a very strong magnet next to it (maybe neodymmium), it will turn the phone on automatically AND bypass all codes and security systems. I dont know if it works on youre phone specifically, but but theres a good chance it does. And if it does, u better hope they dont know abouy that secret.
