Rasane Seto on Nostr: Using a signer (while still having your pair backed up in a password manager) ...

Using a signer (while still having your pair backed up in a password manager) alleviates the former issue, but I do agree that the latter (especially when users from 2021-25 get compromised) is a major issue.
