How do I unlink Google accounts?

Question

I accidentally linked two of my google accounts, so when I log into one it logs me into both. I cannot seem to find a way to undo this. How do I separate them again?

From Sign in to multiple accounts at once - Accounts Help

Signing out

When you sign out of any account, you’ll be signed out of all your accounts on that browser. If you want to use multiple sign-in again, follow the steps in the “Add your Google Accounts” section above again.
To sign out of all accounts:

1. Go to your Google Account page.
2. Click your profile photo or email address at the top right of the page.
3. Click Sign out from the drop-down menu.
