Identity vs Account

Identity instead of account. What's a key and how do you back it up?

Planetary implements the secure scuttlebutt protocol. It's different than centralized systems because you don't have an account.  Instead you've got an ed25519 cryptographic key pair, a public key which is your identity and a private key which lets you publish content. This is very similar to how a bitcoin or ethereum wallet works. 

You can take your identity keypair and move it from Planetary to any other compatible application. All of your followers, content, and relationships will move with you.

Planetary never stores a copy of your keys, we never see it, they are yours and yours alone. By default they are stored encrypted and kept as a backup using apple's icloud/keychain service. We recommend that users are in control of their identity so you should keep a secure backup elsewhere.

How do I get my key?
