@corbet My credit union's new bill pay system wants me to do login credential sharing.
Their CTO actually responded to me when I complained, and essentially told me they they couldn't afford the good bill pay platform any more and this was all they could offer.
So all the bills that want credential sharing I'm now entering information manually.
The credit union have otherwise been good, so I haven't abandoned ship, but wow the bar seems to be low for software in the financial sector.
