Hello @jonathan22,
We haven’t received any reports from other users, like you, who received an error message saying “You are already signed in on another device” when signing into your bank account.
But first, may I know any name or details of your bank account? Any information you can share will be appreciated and can also help me look for any reported issue specifically related to your bank.
Thus said, let’s log into your bank account in a new incognito or private window of your browser. This can help us check if the error message is related to your browser or not. To do so:
- Google Chrome: Ctrl + Shift + N
- Mozilla Firefox: Ctrl + Shift + P
- Internet Explorer: Ctrl + Shift + P
- Safari: Command + Shift + N
After doing so and you can login without any errors, you can clear your browser’s cache to remove your browsing history and your browser can start from scratch.
However, if you still receive the same error message, let’s switch and use a new browser application. From there, you can go back and log back into your bank account.
Know that you can always visit our Help Articles page for QuickBooks Online in case you need some tips and related article for your future tasks.
If there’s anything else that I can help you with, please let me know in the comment section down below. I’ll be always around ready to help.
