Allowing multiple people to access User 1
This approach depends on the OpenID Admin module. Here are the drush commands to download and install it, and set an openid access:
drush dl openidadmin drush en -y openidadmin drush openid-add 1 https://your.openid.server/your-open-id
This can allow you to simplify development workflow and easily control who has access to User 1, without giving away that account's username and password.
