Comerica Bank Automated web connect download of transactions no longer works


I have been using quicken for many years to automatically download transactions from comerica bank ( or using web connect, then about 6 to 8 weeks ago, it quit working. I tried several things (reset, etc..), but to no avail. I then deactivated and tried to setup online automated again. When I try to setup automated downloads now, its says I have an invalid id and/or password (CC-503), but I know the id and password are valid and work…. Again, this was working for many years. Very frustrated. I can manually export transactions (in .qfx format) from the comerica bank website and import into quicken, but thats all manual. I want my automated downloads working again. Can you please help get this fixed?

    Hello @Jeffrozica,

    Thank you for reaching out to the Community and telling us about this issue.  I'm sorry to hear you're running into this problem. If you haven't done so already, I recommend following this troubleshooting from our article on CC-503 (invalid credentials error):

    Step One: Verify your bank login information

    1. 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.  

    1. 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

    1. Go to your bank's website and use your credentials to log in to the bank's website.
    2. Confirm that you're able to log in to the bank's website with the expected username and password.

    Step Three: Update your password(s) in Quicken

    1. Launch Quicken and go to Tools > Password Vault > Add/Edit Passwords.
    2. Click on the account in the Password Vault.
    3. Choose Delete Password for the account.
    4. Complete a One Step Update, you will be prompted to enter the password manually.
    5. 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.
    6. 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:

    1. Choose Tools > Account List.
    2. Click the Edit button next to the account you want to change the login ID for.
    3. In the Account Details window, click the Online Services tab.
    4. Click Deactivate, and then click Yes to deactivate online services.
    5. Click Yes again, if necessary, to confirm your choice.
    6. Repeat these steps to deactivate all accounts at this same bank.
    7. Return to the Online Services tab, and click Set up Now for each account you've deactivated.
    8. Enter the correct login ID and follow the on-screen prompts to activate your account.

    Thank you.
