No, both discussions are about OAuth2.  For Google, Microsoft, Yahoo, AOL, 
an others.

As David also said, that option will not provide the same function from a 
user's viewpoint, as you cannot use IMAP and SMTP with a public client 
application.  So registering Emacs or Gnus as a public client application 
would be useless.

Thunderbird uses an application id / secret, see [1].  And "All activities 
that occur using your Access Credentials are your responsibility. Access 
Credentials are non-transferable and non-assignable. Keep them secret." 
(see 2.b in [2], and in attached file).
