CC-503 Error with SSFCU – Ongoing for 2+ Weeks, No Resolution

Hi all,

I’ve been experiencing a persistent CC-503 error when trying to connect to Security Service Federal Credit Union (SSFCU) via Quicken for over two weeks. I’ve taken the following steps:

• Successfully logged into SSFCU’s website using my credentials
• Changed my password to ensure compatibility (no special characters)
• Verified with SSFCU support that the issue is on Quicken’s end

Despite this, Quicken continues to reject the login during One Step Update. I’ve tried resetting the account connection and updating the Password Vault, but nothing has worked. SSFCU confirmed they maintain technical controls that may block third-party access deemed high-risk.

I’m using Quicken Classic Premier 2025 on Windows 11. Is anyone else still seeing this issue with SSFCU? Has Quicken acknowledged it or offered a timeline for resolution?

Any workaround suggestions (like QFX imports or switching connection methods) would be appreciated. I’d prefer not to manually import if there’s a fix in progress.

Thanks in advance!

Debbie
