Hello @Spamhater007
Thank you for reaching out on the community and telling us about your issue. If you'd like to remove an online biller from your bills and income page in the top right you'll see a cog wheel with a drop down menu.
From here you should see manage online billers and will let you change the password or remove the biller.
Please let us know if this helps resolve the issue for you.
Thanks,
Quicken Francisco
