I was curious to see if FairEmail could work with OAuth without Google Play (I have a school Google account that does not allow me to log in without OAuth):
"OAuth for Gmail is supported via the quick setup wizard. The Android account manager will be used to fetch and refresh OAuth tokens for selected on-device accounts. OAuth for non on-device accounts is not supported because Google requires a yearly security audit ($15,000 to $75,000) for this. You can read more about this here."
Yes, I switched to it from K-9 for the work O365 we now have to use, sigh. (There is a large XOAUTH patch for K-9, but it hasn't been incorporated as far as I know.)
Not having that n the F-Droid version is a pain, but it does phone home to alert you about updates, one hopes without trafficking in that traffic.
Using both this and k9 without Google play or any Google. They work great. But both of them, no longer allow storing your mail and/or attachments on 'external' or SD card. That is frustrating. This anti feature, just started in the last few months.
Could be a new API that needs to be supported. I just downloaded another app (NewPipe) that let me specifically choose some new API that made its external storage permissions work.
No thanks for me, my gmail account will always remain disconnected from anything else.
Better have alternative google accounts for logins, android apps etc which are not tied to primary especially on the phone.
