Quicken CC-503 and CC-501: Fix the "Incorrect Login" Update Errors

You run One Step Update and Quicken stops on CC-503 (“incorrect login”) or CC-501 (“having a problem connecting”).

Why: These look similar but have opposite causes. CC-503 means your financial institution actively told Quicken your stored username or password is wrong — usually after you changed your bank password, or because the bank now wants a separate password for third-party apps. CC-501 means the bank is blocking Quicken’s connection from its end; your credentials may be fine. Match the fix to the code.

Fix 1: CC-501 — wait, because it’s the bank’s side

Per Quicken, CC-501 is “usually caused on the bank’s end” — Quicken is blocked from connecting, and the company is typically already aware and working on it.

1. Wait 24 hours, then run One Step Update again. This clears most CC-501 errors on its own.
2. If it still fails after a full day, contact Quicken Support — these often need an agent to review connection logs.

Don’t bother deactivating and re-adding accounts for a fresh CC-501; that won’t fix a block on the bank’s server.

Fix 2: CC-503 — confirm your login at the bank’s website first

Before touching Quicken, prove the credentials actually work.

1. Open your bank’s website in a browser and log in with the exact username and password Quicken is using.
2. Look for any notification banner — some banks make you re-authorize third-party access or accept new terms before Quicken can connect again.
3. Some institutions require a separate login/password for third-party software (Quicken). Check your online-banking security settings for that.

Watch for special characters. Quicken notes that &, <, >, \, and / in a password can trigger errors. If yours contains one, change the bank password to something without them, then update Quicken.

Fix 3: CC-503 — delete and re-enter the password in the Password Vault

Once you know the correct password, force Quicken to drop the stale one.

1. Tools → Password Vault → Add/Edit Passwords.
2. Select the account, then choose Delete Password.
3. Run One Step Update. Quicken will prompt you to type the password manually.
4. Enter the password (the same one that works on the bank’s website), tick Save, and click Update Now.

If you don’t have a Password Vault entry, instead go to Tools → Account List → Edit → Online Services tab → Reset Account, and follow the prompts, carefully linking to your existing accounts.

Fix 4: CC-503 won’t clear — deactivate and reactivate

If a corrected password still throws CC-503, rebuild the connection.

1. Tools → Account List → Edit next to the account → Online Services tab → Deactivate. Repeat for every account at that bank.
2. Tools → Add Account, choose the bank, sign in, and Link the found accounts back to your existing ones (don’t create duplicates).

FAQ

How do I tell CC-501 from CC-503 quickly? CC-503 is a credential rejection — start by checking your login. CC-501 is a connection block on the bank’s side — wait 24 hours.

Will deleting my password in the Vault lose data? No. It only clears the stored credential. Your transaction history is untouched.

My password is correct but CC-503 keeps coming back. The bank may require a separate third-party password, or your password contains a character Quicken can’t pass (& < > \ /). Change it at the bank, then re-enter it in Quicken.
