caBLE is not a specification for transferring secrets, but for mediating (temporary) access to them.

But the FIDO alliance is apparently working on that: https://fidoalliance.org/fido-alliance-publishes-new-specifi...

I actually thought it was more for mediating confirmation of access to them. You don't share the secret with the new party, but you and the vendor both do a flow with them to confirm that someone claiming to be an identity can support that claim.
