I am an Apple Certified Support Professional with over a decade of experience supporting families, schools, and businesses. Tech has always captured my imagination, but it's not my only passion. I'm an ordained Anglican minister; Aeropress is a daily ritual of mine; I've driven across Mongolia; and I'm the father of three girls. I hope to provide for you a balanced and realistic perspective into the practicality of technology.
I learned this tip on Twitter the other day, I think from @marcoarment. I had never thought of encrypting my iPhone backup file, since any important data would already have been encrypted anyway. What he mentioned is that by encrypting your entire iOS backup, all your saved passwords will also be backed up. Without this option, they are left out of the backup file. Anyone who logs onto many wifi networks, web services, social networking apps, email accounts, etc will benefit from using this feature. It's located under your device's Summery tab within iTunes. The next time you upgrade your iPhone or iPad, or have to do a full restore, you won't be endlessly prompted to re-enter all of your passwords. Do your future-self a favor and check that box.
