We have now some servers based on Elixir/Phoenix, including the https://pareto.space backend.
They have proven to be quite reliable, including for the Nostr-related tasks.
I personally enjoy developing in Elixir with Cursor.

Now a single click/tap selects an image in the Pareto client so it should also work on mobile for you.

Any more feedback appreciated!

Has anybody explored the possibility to store an nsec inside a Passkey?

Passkeys are available on more and more operating systems, browsers, and password managers.

In certain setups this would work even across different devices.

I don't know enough about Passkeys but could imagine that they could carry additional information like an nsec.
