You shard your key in many parts and give it to semi-trusted operators to sign stuff in your behalf.
Later you need to be able to contact these operators to get their shards back so you can rebuild your key, or ask them to delete them. So you need an alternative authentication mechanism.
Doesn't have to be Google, as I said above, it can be any other method, but Google was easy enough to start with and would reach lots of people.
