Error 187 in QuickBooks occurs when the bank's security requirements are not properly entered during the re-linking process, Claire.
This error is often caused by missing security questions or incorrect entry of a one-time passcode (OTP). To resolve it, log into your bank’s website to verify or reset any necessary security information. Make sure to follow the on-screen instructions to update your credentials. If you’ve forgotten the answers to your security questions or misplaced your OTP, your bank can assist you in resetting them and restoring access.
If you’ve completed these steps and are still experiencing the error, I'd recommend contacting our Live Support team for further assistance. They’ll work with you to troubleshoot and resolve the error.
