You can take an existing secret key and Shamir Secret Share it, then use those shares for FROST signing. We will feature this for loading an existing Nostr key into Frostsnap devices.

You could also use an existing key to seed your secret polynomial in FROST key generation. You'll still need to backup the inputs you receive during key generation such that you can recover this secret share. Perhaps this can be a single shared transcript.

Or bring your own key in another sense?
