@PeterJones This also happen’t to me. Trying to use login via my Github account, but got an error, This site can’t be reached (see output in PS!).
Anyway, got an email from github:
The link was already made even though the Auth site couldn’t be reached. Revoked Notepad++ Community access from my github account. I was logged in, but I deleted my account since I had revoked access to my github.
Using my google account to login worked but after ~1 hour and a half, I’m still waiting for an email confirmation?!!!
PS! Tried again, through my Profile to change “Single Sign-on Services” association from Google to Github.
Still got the message (Note! XXX… replaces possible privacy revealing tokens. And replaced ‘https’ with ‘h-tps’ because of spam warning):
Again,- had to revoke Notepad++ Community access from my github.
