The instructions provide clues, but don’t spell out, how to set up org2blog for multiple blogs. https://github.com/punchagan/org2blog

(setq org2blog/wp-blog-alist 
  '(("wordpress" :url "http://username.wordpress.com/xmlrpc.php"
     :username "username"
     :default-title "Hello World"
     :default-categories ("org2blog" "emacs")
     :tags-as-categories nil) 
    ("my-blog" :url "http://username.server.com/xmlrpc.php"
     :username "admin")))

But what if you don’t want to specify your username and password in this multi-site set-up?

The answer lies in expanding on the elisp provided.

(let 

 (creds-stevedowe creds-warpuni creds-status)
 (add-to-list 'auth-sources "~/.netrc") 
 
 (setq creds-stevedowe (auth-source-user-and-password "stevedowe.me")) 
 (setq creds-warpuni (auth-source-user-and-password "warpuni.com")) 
 (setq creds-status (auth-source-user-and-password "status.warphost.net"))

 (setq org2blog/wp-blog-alist 
  `( ("stevedowe.me"
      :url "https://dowe.uk/xmlrpc.php"
      :default-categories ("me" "process" "things" "world")
      :tags-as-categories nil
      :username ,(car creds-stevedowe)
      :password ,(cadr creds-stevedowe)) 

     ("warpuni.com"
      :url "https://warpuni.com/xmlrpc.php"
      :default-categories ("Analytics","BioData","FreeSoftware","Internet","Mobile","News","Productivity","Security","Social" "Support")
      :tags-as-categories nil
      :username ,(car creds-warpuni)
      :password ,(cadr creds-warpuni)) 

     ("status.warphost.net"
      :url "https://status.warphost.net/xmlrpc.php"
      :tags-as-categories nil
      :username ,(car creds-status)
      :password ,(cadr creds-status)))))
