I've been trying to figure out how to do the same thing, that is, add an already existing second vault in Dropbox to 1Password on a second computer. The knowledgebase article given above speaks to setting up Dropbox sync. My second computer syncs my main vault just fine, but there's no way I can see to add a second vault created on another computer. "New Vault" under the 1Password menu assumes one wishes to create a new vault. In 1Password Preferences>Sync I would expect to see a plus symbol "+" in the left sidebar labeled "Vaults" (plural), but there isn't one. My main vault is there, of course, but how to add one is the question. And Allow creation of vaults outside of 1Password accounts is already checked under Preferences>Advanced.
I'm using 1Password 6.7.1. I've used 1Password since v. 3 and thought I knew my way around pretty well, but I'm stymied.
Your question is different than the one in the previous discussion, so I've moved your message to a new thread. I hope you don't mind!
If you have a sync file in Dropbox for your secondary vault (.agilekeychain or .opvault), and if "Allow creation of vaults outside of 1Password accounts" is enabled in 1Password > Preferences > Advanced, all you need to do is find that sync file within the local Dropbox folder on your Mac and double-click on it. 1Password will prompt you to create a new vault (if 1Password is locked, you'll need to enter the master password for your Primary vault first).
Hopefully this helps, but please let us know if you have any trouble with that, or if you have more questions. Thanks!
Hi @Drew_AG I've tried double clicking but no luck
Is there anything I can do to trouble shoot?
@Bonnie_Bootleg - Sorry to hear that didn't work for you. To be clear: you double clicked a .agilekeychain or .opvault file in Dropbox on your Mac (not in a browser), and you've already gone to 1Password's Preferences > Advanced tab and clicked the box marked "Allow creation of vaults outside of 1Password accounts?"
Having the same issue, but i have upgraded to 1PW 7 where the agilekeychain is no longer supported... How do i add my agilekeychain vault that is stored in dropbox to my newly installed 1pw 7??
@mkman - sorry for the trouble. The way you'll need to add a legacy Agile Keychain vault is by using the File > Import command and choosing the top option ("1Password Keychain"):
Choose the vault you want to import the old Agile Keychain into, then click "Choose File," navigate to the proper Agile Keychain file in 1Password and proceed with the import. You'll need to make sure other devices are not still linking to the old Agile Keychain, or you'll start getting discrepancies in your data. After the import, if you choose to sync via Dropbox once more, the default is to write out a new OPVault; make sure you switch all your devices over to the new keychain.
