I'm a user of 1Password and a huge fan of the service but I'd really like to have a device sponsor another device automatically (like how iCloud does it) instead of having to present the secret key to the user to manually input into the new client.
Curious if you've had a chance to try the Setup Code? It's not as slick as iCloud since we don't own the OS, but it enables you to scan the code and get all the account details on your new device. That way all you need to do is type your password.
On that note we recently had a hackathon around this to make things even simpler and we had some success there. I'm hoping we can make this real and share it in an update later this year.
The obvious benefit of a secret key is its high entropy. But I also like how the secret key discourages me from logging into 1Password on anything but my own, trusted, devices. In my view, password managers should not be accessed from other people's computers or internet kiosks.
