1Password 8 will not forget my account

Hi there jgawrych

You're quite right that you can remove that Keychain item, although you can also right-click a "found" 1Password account on the Sign In screen and click "Remove Account from List", like this:

This means you can remove it without having to leave 1Password or open a system utility.

I'll mention this to our Docs team to see if we can have the 1Password Support website updated, perhaps on the Sign out of 1Password or How to add another 1Password account to the apps and browser extension articles. :)
