- Easy local backup of your nsec or ncryptsec - Email yourself your ncryptsec, as an additional backup location - Create a multi-signer bunker URL for Nostr Connect (more info below) - Auto follow the contacts list of some old and trusted Nostr users - Customize of contact suggestions, useful for onboarding friends & family

Try Nstart live at https://start.njump.me or watch this video to understand how it works: https://chronicle.dtonon.com/77b9a397cbbcd63f3bfc78ff2b2c060...

For devs: it can also be used by any Nostr application, web or mobile, to offer an easy onboarding flow! You can integrate it effortlessly via a simple redirect, modal or popup: in the end, the user is automagically logged into the app, without needing to touch their keys/bunker. https://jumble.social, https://flotilla.social, https://nosotros.app, nostr-login (and so every website that uses it, like https://npub.pro, https://nostr.band, https://www.whynostr.org, etc..) are already using Nstart, check them.

A note about the multi-signer bunker. This is really cool stuff made by @fiatjaf, that uses FROST to split your nsec in 3 (or more) and distribute each shard to an independent trusted remote signer. This will give you a bunker code that you can use to log in to many web, mobile and desktop apps without exposing your nsec. If you ever lose your bunker code, if the signers vanish from Earth, and it stops working, or if it gets stolen by a malware virus, you can use your nsec to create a new one and invalidate the old one.
