@v Really curious on how the device linking flow works in Farcaster, when you log in from another device? Is it generating another keypair and assigning it as signer for my fid Or is it more like Object Capability tokens?

It’s using ECDH to set up a secure channel to transfer your recovery phrase to your other device

Interesting. This makes sense. Essentially the same key living on both devices.
