Touch ID Security affected by Mac login password?

Hi,

On my Mac I have Touch ID activated to unlock 1Password and set it up so that 1Password asks for my Master Password once per week to re-activate Touch ID. I also read your article about Touch ID security (https://support.1password.com/touch-id-security-mac/) and noticed under the "Protect yourself when using Touch ID" section right at the end of the article you mention:

"Don’t share the password you use to log in to your Mac. If you enable Touch ID in 1Password on your Mac, it’s important that you guard the password you use to log in to your Mac closely. Anyone who knows it can unlock 1Password."

Especially the last sentence has me worried. Why would anyone knowing my computer password be able to unlock 1Password? Does my computer password allow access to the secure enclave that powers Touch ID and subsequently log in to 1Password without the Master Password? Or what is the concern here?

Thanks for any clarification on this.

Best,
Johnny
