Chain of custody presents a significant challenge when onboarding existing users who already have an EOA with Warpcast (neé Farcaster). 

If users import their existing Warpcast EOA into Uno, we gain full custody privileges to the FID. This creates a support challenge, as Uno users may reasonably expect us to help them transfer their FID to a new EOA when needed.

But what if the user expects support to remain with Warpcast?

Additionally, there's a notable security concern. If net new Uno users export their EOA to another client that subsequently has a security breach, we might not be able to help them recover that FID. It could be transferred away forever!

But given our confidence in our app security practices, we are more than happy to give more limited scope permissions via an auth address EOA. We'll just point you to the original app for customer support.

Yep. We'll generate an Uno EOA locally independent of the Warpcast EOA.

The only thing I'd like to see is the fname registry updated to support multiple EOAs/auth addresses so you can manage a username proof, cc @horsefacts.eth

unless i'm not following here, is what you're saying that for existing warpcast/farcaster users you'd just register the uno EOA as an auth address? that makes sense to me
