I'm just here learning about lightning network and discovered this cool stacker news website :) trying my 5 free comments :)

I have installed Breez wallet and did my first lightning login ever by taking a picture of the QR here and my mind was blown.

This is so cool to be able to login in a site like this! Where can I learn more about what is really happening under the hood when doing it? What information is sent from my wallet? And is Breez ok to use? I read that Muun was recommended but I guess Breez works too. Is there any other wallet I should have a look?

Thank you and have a great weekend.
