You can install bitmessage authorization listener to as many computer you want to avoid the single point of failure.

The authorization providers has 2 purpose:

• The ability to fight spam: Stop creating new users from "thin air". You can ask captcha, request proof of work (via bitmessage) or similar to make it hard to create high amount of users. Without it anyone could make 1000+ users/second.
• To reserve usernames: Does not signs your request if user already exist with same name.

If you don't need this features you can create a zeronet-only authorization provider by publishing the private key, but it's not recommended.

No Bitmessage support built-in zeronet, but you can register by downloading the client and sending "add:#$auth_address:#$username" message to BM-2cUhFY6Ay2LSZZTJ1por17uRWa2oXGQKuK

The source code is here: https://github.com/HelloZeroNet/ZeroID

Basically you have to return a cryptography signed useraddress#web/usernamestring to user.

He saves the sign to data/users.json and then using it he will be able to publish content to sites that accepts his authentication provider.
