More and more I'm seeing login screens where the username is on one page and the password entry is on another screen. The Economist's website was the most recent site to do this.I can understand why this happens in certain exceptional cases. For instance, Microsoft's account might require you to log in on your organization's own site.But for most websites, this makes no sense to me. It makes it harder to use a password manager to automatically fill in your credentials. I don't see how this is "less work" at a UX level since you end up having to hit more buttons. Was there some UX memo that this improves conversion that I haven't seen?
