I just set up a whole backup solution for my many self hosted applications, all encrypted with the keys safely in my password manager. Even uploaded to S3, because I figured if I'm paying for it, I could ID-and-support ticket my way to my data even if I lost my AWS credentials.
I don't know how to integrate a security key into this scheme. What to do if it actually gets lost ?
Will I have to use emergency codes for all the accounts ?
Can I make a backup of it somewhere ?
Would that defeat the purpose ?
I'll buy one someday, when I'll have all this figured out.
