today you have to create a new signer for each device that you use with opencast on, which isn't great ux. would like to experiment with ways to address this without exposing user accounts to the risk of plaintext keys being stored in a centralized db

some initial ideas
1. populate the signer from a passkey somehow (i think largeBlob enables this?)
2. metamask snap for farcaster signers (would also enable you to sign into many apps with the same signer)

lmk if you have thoughts on this :)

Investigate the technical feasibility of both options in depth.Consider user privacy and data ownership implications
