1PasswordEditor: Rene Ritchie
1Password for iPhone and iPad is a password management app that lets you generate, store, and fill strong, unique passwords for all your web logins. What's more, 1Password will also store and fill your credit and debit card information, backup all your software licenses, and lock down any secure notes you want to keep.
While Apple includes the free iCloud Keychain service in both iOS and OS X, it doesn't include the "master password" feature of 1Password. With a master password you can, for example, hand your iPhone or iPad to a friend, family member, or colleague without having to worry about them accessing your passwords and card information.
