Good idea.

I've been thinking about this also. For now, before we have a technical solution, we could post a note and keep it in our public bookmarks.

Below is the Npub of my account backup #1. I have set my main account to follow my backup account. I will keep the robot avatar for my backup until I use it.

Possible hashtags to find the note:

#Npub

#MyNpub

#MyNostrBackup
