Closing Bank of America checking account but keeping credit cards

I am considering closing my Bank of America checking account due to the monthly fees that will kick in for me soon. However, I’d like to keep the credit cards. As I understand, this is possible and they are considered separate accounts (correct me if wrong). My main question is whether my online banking access would still be available after closing the checking account. For example, I use the website to see and pay the credit card bills (I’m not using the checking account). Just curious if anyone went through this. Thanks.
