A cute, little video from Jonathan Mann about how to choose a master password for 1Password on [iOS](https://itunes.apple.com/us/app/1password-password-manager/id568903335?mt=8) or [Mac](https://itunes.apple.com/us/app/1password-password-manager/id443987910?mt=12).[^aff] Of course, I still prefer [another one of Jonathan’s songs to this one](https://www.youtube.com/watch?v=dfbHiMX_arw).
