Maybe I'm doing something wrong, or maybe the default password app won't do what I need but I wonder if you all can help. We have a corporate wifi spot that I can access, the first time I try and browse, it brings up a wifi login page. I can sign in and it works fine the rest of the day. I've added a profile to the password manager that includes the sign on and url, but I still manually have to type the user/pass in. Isn't there something where it will do it for me? Also we are forced to change passwords every 30 days, so whatever alternative I have, I need to be able to update the profile at least once when it changes
