GPG Keys, authinfo.gpg, and Emacs passwords (Magit Forge)

Magit Forge allows accessing PRs, issues, etc. directly from Emacs but requires using auth-sources in Emacs. To have Emacs use an encrypted file (please do this...) the following must be set in the Emacs init file:

(setq auth-sources '((:source "~/.authinfo.gpg")))

You must then create the ~/.authinfo.gpg. This is done simply by opening that file in Emacs. If you already have GPG setup you just need to select your own GPG key (mark it with m in the Emacs interface). Make sure that the permissions for the ~/.authinfo.gpg are 600.

You can add the Magit forge (and other passwords) into the file (see the Magit forge documentation). See here for info on manually creating the GitHub token.
