I've been pondering a trusted network using shamir secret sharing for this case - where you can rely on other parties to hold the secret key and call on them. For example, origin player loses 2FA to system A, origin player calls out to their immediate backup personnel (origin player sets limit of how many are required to recover secret). Each backup personnel can say OK - sending partial to system A, once enough have been sent the secret is recovered. Complex, and time in-detriment, and still prone to failure or breach of trust.
