My normal internet linkup with Google drive doesn’t have them send sms codes but Libre Office seems to think I need one?
In future please search the forum for answers before posting. This has been asked/answered before.
Please see answer by sberg in this post → LibreOffice access to Google Drive asks for authentication 6-digit pin
This has never been answered by Libre Office and no solution is posted. The programmers don’t seem to understand true feedback. Until this is resolved the program is broken. Older versions were fine without this “feature” bug.
The link does explain the problem & that a fix will be forthcoming by v6.2. This is only a problem for some users. For me single & 2FA have worked for a very long time.
Since the current version is 6.1.2 this solution looks to be a year in the future. A patch would be a better solution until then I have to save send to Google drive and download outside the program.
v6.2 is scheduled for release in late January 2019 - Release Plan. Comment by author states it may be backported.
Can’t give you whys of when something is scheduled. I am just a user like you as are most who answer questions on this forum are.
