Microsoft O365 and Google G Suite are both retiring basic authentication for client access to mailboxes. As a result, ALL clients will need to support OAuth on a very short timeline.
End-user MUAs aside, I'm worried about systems that rely on a mailbox for integration (RT, and the like). I suspect that there is a long tail of those systems that are critical to line-of-business operations which don't switch to OAuth in time (for a variety of reasons). I was holding on to "app passwords" as the last bastion for these systems to integrate. It's unclear if Microsoft will continue to support app passwords with their Azure AD MFA product, which only works for organizations who don't federate authentication to a local IdP anyway. Google plans to stop creation of App Specific passwords in June 15th, 2020 and grandfathering in the rest until February 2021.
