If it helps you I work for Fortune 500 company which uses gmail with 2 factor authentication and we are using IMAP with gmail just fine. from time to time mail mate pops up asking me to reauthenticate. I don't see how 2FA changes the security implications here. what they could argue is that it

In my opinion as someone whose primary research area, for more than 30 years, has been security, your email credentials are the most valuable you have. I would add that this opinion is shared by most security professionals. Why? Because your email account is used to reset access to almost every ot

My university implemented mandatory Duo authentication about a month ago. To my extreme surprise MailMate handled it transparently. I had zero problems and did nothing explicit. I still don’t understand why. By comparison, my iPad needed to have the whole email account deleted and reinstalled.

Yeah imap and 2FA is a problem. I looked into it some time ago because I wanted to implement it for my employer because we have a medium-sized commercial email-platform. Adding 2FA to a web-application is no problem these days. But with imap the only chance I see are only workarounds for the set

Duo has (at least) two modes of operation. One is a standard time-based one-time password: the site supplies you with a key (often via a QR code), and your phone calculus F(key, time). The other is a bit more complex: when you try to log in, the site sends a push message to your phone; you unlock
