Indeed this is a critical point. There's nothing worse than using your Nostr app for 3 months and then losing your account because your phone breaks and you haven't saved your password anywhere.
Do you have any suggestion to improve this aspect on Nstart?
I would encourage the nsec to be stored in multiple places (and different mediums), just like any critical/important data.
I have mine written on paper, in a ziplock, in a "fire proof" safe, along with ascii txt files on external drives.
The user is already instructed to do so and must confirm the step:
I would not want to block it too much at this point with specific instructions on how/where to save it. Maybe it could be added at the end.
That looks great!
If you want to provide more details, I'm thinking an external link for "Best practices for securing a key" would do the trick.
I think what you have now is fine without it though.
