Authentication with Lightning Node / Wallet

Horndev commented 4 years ago

The solution (s)

Instead of a username and password, a user should be able to sign in using either a message signed by a node private key, verifiable with the node public key.
Alternative sign-in would be a payment of 1 satoshi originating from the registered account public key.
Maybe a data packet with no actual payment from the account public key could be used.

Additional context If this could be implemented as a standard c# library using the Authentication framework (OWIN, or other), that would be very useful for multiple users!
