This is something I learned quite some time ago. If you encrypt your backup then after your upgrade or your move to a new iPhone, your passwords will still be there. This means things like Dropbox, Wi-fi, and email for example will work without you re-entering your password.
Encrypted backup is done like below.
I do in fact normally use Cloud backup as that is easy. But for upgrades I use an encrypted backup as that makes the whole process very quick and easy.
Why am I sharing this with you? It turns out that this did not work for me when I upgraded to the iPhone 6. So I had to re-enter all of my passwords. What a hassle. Even had to redo my fingerprints but I expected that due to their nature and the fact they are associated with a specific chip in my old phone.
So instead of a fast upgrade to a new phone, set aside a little more time for dealing with all of the passwords you may not remember too quickly!
BTW, here is an Apple KB article that says I remember things right, and while it doesn’t say iPhone types or iOS versions it does implies it should still work as I think. So either a bug or perhaps I made a mistake. I would love to hear in the comments how your upgrade to a new iPhone went. BTW, I love my new iPhone 6.
