rundown of the different Ethereum accounts that are part of your Farcaster experience

note that most of this isn't directly applicable to end users (just like an end user doesn't think about OAuth credentials)

why so many? in short, they serve different functions and have different permissions. combined they yield a self custodial, user friendly account that is safely portable across clients and captures your full onchain public persona

- custody address: holds your FID, root key for your FC account

- recovery address: can recovery your FID if you loose access to the custody account, by default a Farcaster (the app) controlled wallet so we can do social recoveries for users

- auth address(es): additional address that can sign in as you, used so you can sign in multiple clients w/o needing to import your custody address, your Farcaster Wallet is automatically added as an Auth Address and used to do SIWF on web
