When did POP and IMAP become a “legacy protocol?”
I get the impression that the article's author didn't really read the linked help page. It's basic auth that's getting deprecated, due to being considered a legacy authentication protocol. For good reasons, as described.<p>That aside, POP should really be considered legacy, it comes with many downsides that hinder people's e-mail usage. IMAP is definitely more functional, but has a successor - JMAP. So in some sense, it'd not even be entirely wrong to migrate.<p>Lack of HTTPS on the author's site also adds a nice subtle flavour to the blogpost.
