Thank you for the detailed information about LNURL-auth! I had been using Breez, BlueWallet and need to try out Phoenix!
Also your feedback as well on using Zeus which is connected to my umbrel node is even better!
We just developed a web app (https://lightsats.com) during the BOLT🔩FUN Legends of Lightning⚡️Tournament which we have enabled LNURL-auth for bitcoiners as the main authentication method!
It's such an easy authentication method and also great for privacy without having to give out any personal identifiable information and also not have to remember an email or password for each site.
Since we launched the web app 7 weeks ago we've been able to get around 600 users which surprisingly 54% have authenticated via LNURL-auth 🎉🎉
I really wish other wallets start supporting it besides just Breez, Phoenix or BlueWallet.
Also some sites have also started allowing users to link multiple wallets to their profile in case they don't have access to the device when trying to access the site, this is the case for the https://bolt.fun site.
