Yeah I’ve not been comfortable with the idea of a single account for all the web, no matter how convenient. One service gets hacked and bang goes all that data
"logging in" with Nostr is quite different than logging in with a traditional account. When done correctly, the service or platform being accessed never touches your keys/credential/secret. This limits the blast radius of a hack significantly. Can't and shouldn't think of it the same way that you think of "an account"
My 2 cents is major app devs need to agree to stop allowing priv key logins (or at least hid them in a sub-menu) and only extension or bunker. But that would mean every iOS app would stop operation.
Yea I think there are two situations: 1) Nostr client login 2) Platforms that allow you to login with Nostr Eventually #1 will be everything, but in the meantime there will likely be a lot of #2s. For #2 the platform just has to be able to prove you have ownership of your npub, which can be accomplished through DM
