Exporting (iCloud) Keychain and Safari credentials to a CSV file

Update (October 2021)

Exporting password + one-time code data from iCloud Keychain is now officially supported in macOS Monterey and Safari 15 (for Monterey, Big Sur, and Catalina). You can access it in the Password Manager’s “gear” icon (System Preferences > Passwords on Monterey, and Safari > Passwords everywhere else), or via the File > Export > Passwords... menu item). You shouldn't need to hack up your own exporter anymore.

Original, Obsolete Content (2014)

After my dad died, I wanted to be able to have access any of his online accounts going forward. My dad was a Safari user and used iCloud Keychain to sync his credentials across his devices. I don’t want to have to keep an OS X user account around just to access his accounts, so I wanted to export his credentials to a portable file.

##Generate and Install IPA's file in device through Command Line

###Thanks to Mattt and phonegap's scripts

Take a note: all this steps can be automatized in a single script, if you know how to write it. (Bash or Ruby will be fine)

1.- Install your Provisioning Profile and Developer Certificate

2.- Install Shenzhen and ios-deploy: the firstone will generate the IPA file and the secondone will install it onto your device
