Can 1Password be made to work with MetaMask Crypto Wallet?

Thanks for your reply Dave. I'm not sure what the "pop-up" is since there are a few different ways to activate 1Pass. I have 1Pass icon in my Firefox toolbar and have not been using it. [Duh!] I always activate the full app with Alfred. I discovered that I can easily copy the password from the toolbar icon and then past it in to Metamask when activate that icon. Easy enough. It will do the trick.

There is one Metamask Snap that is "an encrypted password manager Snap designed to work with… dapps that have implemented the EthSign Keychain API" I don't know how close this is to what we currently know as Password Managers for Web2.
Something that might be worth exploring if you have a roadmap to evolve 1Pass into a Web3/Dweb app.

However, your answer helped me discover a better way to use what is right there. Thanks.
