Exactly. This allows users to create a brand new account, and the nsecbunker keeps their private key for them and allows them to retrieve that key if they want (or if they lose access, to regain access using an email address the way that most people users on the internet are accustomed to).

Users can always take their private key and delete their account on the bunker but I imagine that plenty of users (just like with bitcoin) don't trust themselves to manage their own keys.
