I'm using Gnus to read newsgroups via nntp. I am using mu4e to read and send e-mails. My e-mail server credentials are stored in
~/.authinfo.gpg so that mu4e can access them.
My problem is that whenever I open Gnus for the first time, I get asked the passphrase of the GnuPG key used to encrypt
~/.authinfo.gpg. It seems that Gnus wants to open that file by default, even though it does not need any credentials to read my nntp sources.
How can disable this automatic opening of
~/.authinfo.gpg whenever I open Gnus?
