currently I'm trying to connect to my gmail.com account via gnus.
Following emacswiki.org: Gnus#Gmail Quickstart guide I get
nnimap (gmail) open error: 'NO (ALERT) Please log in via your web browser: https://support.google.com/mail/accounts/answer/78754 (Failure)'. Continue? (y or n) n Couldn't open server on gmail
Searching suggested page by google did not provide solution I could use.
Where did I went wrong?
