I have most of my things at one major bank. Credit cards, checking, savings. Investments are scattered about, but the stuff I need to monitor often is all at one bank. It's a lot easier and helps me keep my sanity. I have their app on my phone and can check it whenever. I do have to log in, but since it is only one login for all the accounts and they all show up on one master screen where I can click on each account it is a pretty fast and simple process.
