[Evolution] Evolution, Imap, Google and half a dozen devices

Evolution 3.38.3 (flatpak gitabb3636)

I run the aforementioned version of Evolution on a half dozen laptops and desktops at various locations

around the world. Access is by imap using OAuth2.

My free Gmail account and my paid for G-Suite account always pop the "blocked attempted access from

unsecure app" about every third time I start Evolution.

It doesn't matter, if it is the same computer 3 times or 3 different computers (even when 3 on the same network)

I'll get that message. And if I don't log into the Google account in question and mark it as me doing the action

the account gets locked out until I go deal with each of the notices.

Has anyone figured out how to prevent this behavior by Google? whitelisting MAC addresses maybe or some

special token from Google? Anything ?

Thanks

Mike
