Try Phoenix Wallet (my favorite), Breez, Muun.

Good Bitcoin wallet apps for mobile are Blockstream Green and BlueWallet. If you want wallets that can do both Bitcoin and Lightning then you can check Muun, Phoenix and Breez.

Honestly, for my daily I just use Muun. It’s hot but self-custodial. Super good lightning integration. https://muun.com Solid company.

Your cold wallet is your savings account. You can top up a hot wallet/lightning spending wallet (your checking account) as and when you need. Recommended lightning wallets, Alby, Breez, Phoenix, Zeus and Muun wallet.

Muun, which is probably the most seamless on-chain + lightning wallet out there.

Muun, Phoenix, or Breez.

I think your definition of open source is not the same as the dictionary definition. Atomic and Guarda are not open source at all and they shill shitcoins as well as staking. I suggest either Blue Wallet or Muun Wallet which are wallets only.

If it is really only about auth maybe consider https://github.com/lnurl/luds/blob/luds/04.md LNURL Auth. But then your users should be able to understand the idea of private/public keys.

The technical specification is here: https://github.com/lnurl/luds/blob/luds/04.md

Since the inception of the lightning network and the development of the ln-url standard, the holy grail of "bank as a web app" is not only a reality but only 5 minutes of set up time and about 30$ of hosting costs away. This starter implements such an app. Authentication and Users are already there, and basic in- and out flow of purchasing power is taken care of. Users can authenticate themselves, deposit and withdraw up to 1000 sats. Whatever happens in between is up to the developer.

Could have been an LNURL payRequest. Unfortunately that does require a service provider, as someone has to be running a server to service the URL. You can host that yourself, of course, but that's way more complex than 99% of Lightning users will tolerate. Many will accept the risks of delegating the hosting out to a third party.

There is a nice article that describes how this feature works on the NFC chip. The URL it produces uses LUD03 and LUD17 from the LNURL spec. This diagram (source) also nicely explains how it works. In this case, the 'User with a smartphone' would be the merchant's point-of-sale device, and the web application would be the LNURL-withdraw server.

And here's specification: https://github.com/fiatjaf/lnurl-rfc

It will take time for the adoption of these standards to increase.

lnurl-auth

That's basically a URL encoded in bech32 with "LNURL" prepended. It's a payment specification called LNURL-withdraw: https://github.com/fiatjaf/lnurl-rfc/blob/luds/03.md

Sorry for the wrong formatting. But that wasn‘t actually me, it was reddit. I just typed an address@like_th.is and it formatted it for me. Actually looked fine when I hit post, but seems to be broken on old.reddit and mobile reddit. Old reddit actually breaks all the links that work fine on new reddit. I can assure you that I posted this because it‘s really fucking cool, and that neither I, nor anyone else, has bought upvotes or comments for it. The spec is part of lnurl, which is very widely adopted. Almost every lightning wallet supports the main subprotocols already. Here‘s the sender side spec: https://github.com/fiatjaf/lnurl-rfc/blob/luds/16.md
