Sure we could integrate Session, Nostr etc but that's a way too much work.
The next issue is account recovery when someone looses access to the key this can end up horrible, an account needs a good protection like 2FA.
Even if Nostr may be nice for some ppl it is super niche and not broadly used. Same with Session. In both cases you tie a service to a key, I the case with Nostr to an identity. I don't see a huge advantage in that case. You can generate a Nostr key just for Mynymbox but than, you forget to read the messages and locked out, lost data ...
I see too much risk for a customer to loose data and domains with keys only.
