Working on a website right now for a company that leverages a bunch of different 3rd party portals to manage the various different accounts that their customers may be using. I was wondering if anyone has ever worked on or used something similar, would love to hear some best practices for handling this sort of thing; and suggestions on how to best prep the user in the case that they may be going off-site to log in.
An example of what I mean handled in a clean, minimal way: (click the log in button to see what I mean.) https://www.umpquabank.com/
Thanks for the input DN!
