(or I can't find it in the menus under email and news preferences), which in turn I take to mean no more GMail from OS/2.

To the best of my knowledge, the latest SeaMonkey we have available (2.42.9esr 20200322125440) does not support OAuth 2.0. Somewhere else, I read how to setup gmail accounts to use OAuth 2.0 under Mail Preferences in ThunderBird, and that it just worked, so I forgot about the issue until I actually tried to do the same recently on SeaMonkey on OS/2. Switch to Office 365, Outlook 2019 (or a newer version), or another email software in which you can login through "Sign in with Google". Instead, you will have to login via "Sign in with Google" or other more secure technologies, like OAuth 2.0.Į-mail software, like Outlook 2016 or previous versions, accesses your Gmail account through less secure means.

To protect your account, Google will not allow to use applications or third-party devices that ask you to login to your Google account using only your user name and password. On May 30th, you may lose access to applications that use a less secure login technology.
