Hi @shrink2!

As rootzero correctly wrote, the Secret Key is not a recovery mechanism, it's an additional layer of protection for your data that makes your encryption stronger. You can read more about it here:

@shrink2 The secret key provides an additional level of protection to your account. It is not a recovery code and cannot take the place of your master password. Both are required to generate the key which encrypts your data and controls access to your account.

Have you tried your old and new master passwords on all your devices and at 1password.com? If so, try writing down your new master password on a piece of paper. Then try typing it into a text document and you might find that your fingers move to different keys due to habit or muscle memory. Make a note of those differences and make a list of possible variations on the original. Then try those variations with and without caps lock, shift key, etc.

Do you have a family subscription? Is there another family organizer who can help recover your account?
