my .NET application is a WPF desktop application responsible for sending e-mail with classic SASL mechanism and/or older one (POP-before-SMTP).
A end-user can select any SASL authentication mechanism on the GUI configuration of this application.
As a developper , I was wondering what where the gain(s) and cost of implementing the oAuth2.0 authentication mechanism availability?
What does the end-user benefit from having this authentication mechanism option available?
The end-user can provide itself with a Gmail account
