Unlock 1Password with ⇧⌘X

I will tell you the story from the start.

One day I found my computer was unable to connect to the Internet because of a problem/error connecting to the proxy server (I can't find the actual error message now). I did a Sophos scan, then a couple of safe boots but the problem was unresolved. Eventually I disabled all proxies from the Mac's System Preferences. I was now able to connect to the Internet but could not connect to my VPN (Astrill).

Astrill told me to uninstall Astrill, then download and reinstall it, and also to uninstall Sophos as it was probably causing the problem. This involved another restart.

When I tried to start up the reinstalled Astrill, I found that my computer didn't know the password (I really don't know why it suddenly forgot). I decided to use 1password to set a new password. That's when I was asked to unlock 1password with ⇧⌘X. (It only occurred to me much later that ⇧ was the shift key). As I said, I managed to start up 1password by opening it and using my fingerprint. But when I asked 1password to set a password for Astrill, I found that it assigned a separate new password for each stage, that is when setting the password and when confirming the password. This meant that I was unable to get 1password to set a new password for Astrill, because obviously the confirmation stage should simply confirm the password and not attempt to assign a new one.

I am afraid that this accumulation of issues (failure of Internet access, inability to access VPN, need to delete/reinstall software, set a new password, need to unlock 1password with a cryptic combination of keys, and inability to set a password with 1password) would be enough to send anyone into paroxysms of frustration.

At any rate, the only remaining issue is why 1password could not set a password for Astrill.
