is 1password windows desktop single user?

Hello @wintermute314,

Thanks for your question.

When using 1Password 8 for Windows and 1Password in the browser in separate Chrome profiles, the extension communicates with the account currently signed into the 1Password 8 app, when the Integrate with 1Password app option is enabled in browser profile. Only one user can be signed into the app at a time. Give this a try to help:
1. Open Chrome and right-click the 1Password icon in the address bar, and choose Settings.
2. Under the General heading, disable Integrate with 1Password app.

If you are both planning using 1Password in the browser and the 1Password 8 for Windows app, you should use separate Windows accounts. Otherwise, you would need to sign out and back in to the desktop client for each user: Sign out of 1Password

I hope this is helpful. Please let us know if you have any other questions or concerns.
