It hasn’t worked for me. Were you successful?
Looks like a 'Login with Nostr' option is available at [vida.page](https://vida.page). It uses your pubkey + relay that you are connected to, to send you a verification code through a DM (I haven't received mine yet). But it's an interesting application that I was waiting for.

Nope, no success for me either. I did not receive the DM.
I received it, but after entering the code, Vida still doesn’t show that nostr is authenticated.
Interesting, in my case no matter what relay I use with my pubkey it doesn't send me a DM.
