You can prove that it's you with a signing extension - like nos2x or alby - on desktop. Then, transfer the cashu from desktop to cashu.me (or other cashu wallet) on mobile via QR.
If that sounds a little too janky, don't use npub.cash, just use the minibits app with a minibits address instead.
You can use npub.cash in cashu.me - no need to teansfer, your zaps automatically arrive in your wallet.
cashu.me > settings > nostr, then "enable lightning address", done.
True. However, if you want to use the npub.cash address that starts with your Nostr npub (of course you would), you'd have to share your Nostr nsec - which cashu.me acknowledges is "dangerous and not recommended".
I should adjust that, it's a bit of an exaggeration. I use it that way. you can also use a signing extension if you want though.
Yeah... the signing extension via cashu.me works great on desktop. I don't believe it's available for mobile, though (at least not iOS anyway).
It think "dangerous and not recommended" could be an exaggeration - but I think that depends on how secure you wish to keep your nsec. Personally, at this time, I consider my nsec/npub disposable, but I still try to practice good nsec hygiene by sharing it no more than is absolutely necessary.
you can use the built-in wallet nsec (or another throwaway one) and purchase a username for it on npub.cash
It hadn't occurred to me to pair a custom address with a throwaway nsec. That's a great idea! I'll definitely keep that in mind.
On iOS you can use the Safari extension Nostash by nostr:nprofile1qqszw70nm86zcl0wzlcwd0xulzdgl82e95v78vdm6fl0rnlarfle35gpzamhxue69uhhyetvv9ujuurjd9kkzmpwdejhgtcpz4mhxue69uhhyetvv9ujuerpd46hxtnfduhszythwden5te0dehhxarj9emkjmn99u3huzze.
