Update.  That is exactly what happened.  They opted for new gmail password.

From the header in a recent email:

Message-ID: 
Date: Sat, 19 Dec 2020 12:33:33 -0500
User-Agent: Mozilla/5.0 (Windows NT 6.1; rv:78.0) Gecko/20100101
    Thunderbird/78.5.1

According to Mozilla, this was a Dec 2 release.

But the last time I worked on that pc, was in Oct.

So.. they probably opted for one more update in the 78.5.x series.
