Hey there, Catfishjas03.
Thank you for making sure you've entered the correct login credentials when connecting to your bank. No worries! I am here to help.
You'll get the error 103 when your financial institution won't accept the user ID and password you entered. I'd suggest accessing your bank's website outside QuickBooks to see if you can login without issues.
If the same thing happens, you can refer to this article for more troubleshooting steps: Error 103 or Error 310.
Should you have questions or concerns, please let me know by replying to this thread.
