How Can a User’s DID and Associated Credentials Be Recovered If They Lose Access to Their Private Keys?

Recovery of a DID without the private key is a significant challenge, but several mechanisms are being developed. One common approach is social recovery, where a user pre-designates a set of trusted individuals or institutions ("guardians") who can collectively approve a key change.

Another method involves multi-factor recovery, using a combination of other devices, biometrics, or passwords stored separately. Some systems may use a designated custodian for recovery, though this reintroduces a degree of centralization.

The key is to have a recovery plan set up before the keys are lost.
