@ tchara
Thank you for the welcome! I am new to k9mail as well as to the forum.
Is it then that this whole thread (or most of it) is misguided? That is: is it that Google’s imminent change will not affect, or at least need not affect, k9mail? The thread contains a pointer to this - but that seems to be a way of keeping k9mail working with Yahoo. What then about Google?
But, ah, I find that Google’s webpages have a ‘Password Manager’. How that manager works is opaque. But I found therein that I had told the manager not to store any password for k9. I reversed that setting, ran k9 on my phone, and nothing seems anywhere to have changed. So, please advise!
