Makes it very simple to transfer nsec key from computer to phone. Don't have to have separate accounts for each device now. 😃

I wouldn’t unless they open source. No promises from a black box “free” service.
BTW… not so hard to copy by hand. Takes all of two minutes including the triple check.
I'm pretty sure you could've just sent a text file over Bluetooth or used Syncthing on both devices. I've also just used a qr code generator from desktop to scan with my phone.
qr code is a great idea. Better than wormhole I think. I haven't sent anything anywhere yet - still trying to figure out how to use nostr. I just found your reply now (two weeks later). lol.
