Idea for account recovery, in case you lose your nsec or it gets compromised:

1. Right now, set up a "failover" nsec/npub pair. Store the information separately from your current nsec/npub pair, and publish the failover npub on #nostr.

2a. In case your current nsec gets compromised (i.e. someone else is also able to post from your account), switch to the failover nsec/npub and disavow the previous npub as compromised, pointing to the message that you published in 1.

2b. In case you lose your current nsec, locate and start using your failover nsec, and announce that you are migrating to the new npub.

In both cases, it would be beneficial if people were *already* following your failover npub.

Perhaps this logic could be integrated into #nostr directly, so that the failover npub can specified as part of the protocol, and that a client knows that when you follow someone you automatically follow their failover npub as well.
