If you lose your device, your website (https://support.1password.com/lost-device/) says to login to 1Password and "remove the device" from your account and generate a new secret key.
What if you're traveling and only have your phone with you when it's lost, and no other device that has been previously logged in with existing secret key, and you don't carry your Emergency Kit with you because it's at home in your safe deposit box, so you don't have the secret key with you? It doesn't seem like you'd be able to login from a newly purchased computer or phone to remove the lost phone from your 1password.com account?
I can see why this is a vexing problem to solve while maintaining your excellent security standards. Please let me know if there is a solution but, if there is no solution to this problem, will you provide an option on your profile to require Two-Factor Authentication at each login from any platform, which I personally would turn on whenever traveling. Thus, as long as your second factor is not the lost device, rather a security key for example, your 1password data on the lost device would be protected by your master password plus the second factor which, hopefully, is still in your possession?
