You can now transfer usernames in nsec.app!
Many people tried nsec.app and claimed their preferred username, but due to UX issues have it attached to throwaway test keys. We've (hopefully) fixed the signup UX, but also added a name transfer feature. You can now transfer your username to your real keys.
Make sure you reload the app properly (open tab, close tab, open again) to get the updated version with this feature. There is a menu button near your nip05 name in the app, where you can request a transfer to a specified npub. That npub then would have to change their username manually to the transferred one to "accept" it.
We've also made some serious improvements to the app, particularly with how well it works when your keys are imported into several devices/browsers. If you've had issues in that mode - please try this new version please.
Here is a quick demo of the name transfer:
