How to delete existing bank feed login and enter a new one for the same accounts?

Good day, @KC_Reiter.

It's nice to have you in the Community today. I can assist you with deleting an existing bank feed log in credentials and enter a new one in QuickBooks Desktop.  

You can edit your login credentials or any information in your bank account connected to QuickBooks Desktop if you disable and re-enable Bank Feeds. This will ensure that the most current information will be pulled from the bank server during re-setup. Bear in mind that only the admin of the account can make the changes.

To do that:

1. Deactivate Bank Feeds for an account.
2. Make the necessary changes.
3. Re-setup account for Bank Feeds.

Also, in case you'll encounter any errors while on the process, you can check out this article for some troubleshooting steps: https://community.intuit.com/articles/1765159-cannot-deactivate-bank-feeds-for-an-account.

This should change the login credentials, @KC_Reiter. Fill me in if I can be of additional assistance. I'll be around to help. Have a wonderful day!
