The last step of adding an administrator is to select a user password for yourself on the cluster you are now in charge of (prod or staging).

In the nixcfg repository, use the passwd utility to set your shell password:

./passwd
> Usage: ./passwd <cluster name> <username>
> The cluster name must be the name of a subdirectory of cluster/

This commited changes to Deuxfleurs' password store, do verify your modifications before pushing them:

cd ~/.password-store/deuxfleurs
git diff
git push

These changes must be deployed to the machines to take effect. Ask another administrator to deploy them. They will need to use the script ./deploy_passwords from the nixcfg repository after pulling your changes.
