I believe this work has already been done, in a series of FEPs based on the Zot/Nomad protocols developed by Mike Macgirvin for Hubzilla/ Zap. Including;
* FEP-ef61: Portable Objects
https://codeberg.org/fediverse/fep/src/branch/main/fep/ef61/fep-ef61.md
* FEP-61cf: The OpenWebAuth Protocol
https://codeberg.org/fediverse/fep/src/branch/main/fep/61cf/fep-61cf.md
* FEP-c390: Identity Proofs
