Daniel Jalkut asked a question on Twitter

There are over 2000 items in my Keychain. So if I want to dump/migrate to e.g. @1Password, do I really have to approve every single access?

The gang at agilebits (makers of 1Password) respond with a set of scripts to completely solve his issue, no questions asked:

@1Password

That, friends, is how Twitter support should and does work.
