Error: 'OOPS! you are already signed in' when trying to verify an alternate email address
When you use a Yahoo email address as your alternate email to another Yahoo account and try to verify it, you'll see the 'OOPS!...' error. This happens because a browser can only hold 1 cookie and can't log into 2 Yahoo accounts at the same time. To fix the error, follow the steps below.
- Return to the inbox where we issued the alternate email address verification link.
- Highlight the verification link.
- Right-click with your mouse and select Copy.
- Sign Out of the Yahoo account.
- In your Web browser's address bar, right-click with your mouse and select Paste.
- Press Enter on your keyboard.
- Sign in with your alternate email address and password.
Your alternate email address is now verified.
