Do you know of any NIPs that add the ability to assign multiple keys to an account?
Or better yet: replace an old key with a new key but retain your social graph?
If you met and followed my friend Brad down in Miami, please welcome him back nostr:npub1zhppe482zepyvh0zl86ll78xrmtcwdg4setyhdjt9fcehaa76ceqe64veh on his new npub 🤣 Making a backup of your private key is important. You never know when or why you'll need to switch phones ðŸ˜

Nope. This functionality doesn't exist. The closest thing would be account delegation NIP-28 or using nsecBunker.
