We are testing two factor authentication for cloud, so that should be up and running within few weeks (we need to test the impact on ux, change howtos accordingly, inform the users). This will be opt-in feature.
It's hard to provide other forms of authentication for other services as we are dependent on developers of those projects to provide such option in the first place.
We hope in the near future to be able to use cloud's two factor authentication combined with SSO for all services. This way once you're logedin to "disroot" in secure fashion, you dont have to retype passwords.
