Use the -i option   ssh -i mykey pem user mydomain com   As noted in this answer  this file needs to have correct permissions set   The ssh man page says      ssh will simply ignore a private key file if it is accessible by others    You can change the permissions with this command   chmod go  mykey pem   That is  set permissions for group and others equal to the empty list of permissions
