Synchrony accounts no longer syncing-error code CC-503

Question

I just recently started having problems syncing with Synchrony (OnePay, Mastercard, & Sam's Club). I get error code CC-503 & a message telling me to check my username & password. I KNOW my username & password are correct because they're the exact same ones I used on Synchrony's website. It appears some people have had a similar issue, but theirs was several months ago. Were they resolved? This is very frustrating!

Hi everyone,

I'm sorry you're experiencing these issues, and I appreciate your patience as we work toward a resolution.

If you're experiencing connection issues with your Synchrony Mastercard, I recommend following the troubleshooting steps below to address the CC-503 error. These steps may help restore the connection to your account.

Step One: Verify your bank login information

* Type your password/PIN into a text application, such as Notepad, WordPad, or other text/word application. * Note: This is a way of confirming you don't have typographical errors in this field.

* Highlight the "confirmed" password and then copy it (Ctrl + C) and paste it (Ctrl + V) into the appropriate fields in Quicken.

Step Two: Verify your bank login at the bank's website

* Go to your bank's website and confirm that you're able to log in with the expected username and password.
* Once you are logged in, review your account at the website for notifications (such as pending messages in a mailbox or message center) to confirm if further action is required to grant Quicken access. * Some banks will require a separate login, password, or both to access accounts on third-party software. Also note, you may need to go to your settings at the website to access these prompts for new credentials.

New passwords: If you are required to make a new password, be aware that some special characters may cause errors in Quicken. These special characters are the ampersand (&), left carat (<), right carat (>), backslash (\), and forward slash (/). Additionally, while Quicken does not have a character limit, your bank may have one.

Step Three: Update your password(s) in Quicken

* Launch Quicken and go to Tools > Password Vault > Add/Edit Passwords.
* Click on the account in the Password Vault.
* Choose Delete Password for the account.
* Complete a One Step Update, you will be prompted to enter the password manually.
* Type in the password (the same one used on the bank's website) and check in the box marked Save next to the password field.
* Click Update Now.

If there is no option to delete and update the password, or if the login ID/username also needs to be changed:

* Choose Tools > Account List.

* Click the Edit button next to the account you want to change the login ID for.
* In the Account Details window, click the Online Services tab.
* Click Reset Account.

* Enter the correct login ID and follow the on-screen prompts to complete the reset. 
* If prompted, carefully LINK the accounts found to the existing accounts in Quicken.

After the reset process is complete, attempt your online session again.

If the issue persists

Try Deactivating and Reactivating the affected accounts:

* Choose Tools > Account List.
* Click the Edit button next to the account you want to change the login ID for.
* In the Account Details window, click the Online Services tab.
* Click Deactivate, and then click Yes to deactivate online services.

* Click Yes again, if necessary, to confirm your choice.
* Repeat these steps to deactivate all accounts at this same bank.
* Return to the Online Services tab and click Set up Now for each account you've deactivated.
* Enter the correct login ID and follow the on-screen prompts to activate your account.

If the issue continues after completing these steps, please contact Quicken Support for further assistance. Let them know which troubleshooting steps you've already completed so they don't repeat them and can escalate the issue in real time if needed.

Regarding the Barclays issue, @ktwomble , since you have a support call scheduled for tomorrow to address the Quicken crashing problem, I recommend letting the support agent know about the Barclays issue once the crashing problem has been resolved so they can assist you with the next steps.

I hope this helps. Please let me know if you have additional questions.
