Restoring Keychain Passwords When Reinstalling OS
I have keychain passwords enabled across all my devices - iMac running Mavericks, and iPad and iPhone running ios7. I chose not to set up a security code as I did not want my passwords stored in the Cloud.
My question is: if I need to completely reinstall my OS, or choose to do a clean install of a future update to OS such as Yosemite, how do I restore my keychain passwords without a security code?
