Exactly our thought! Some users might be sceptical about payments with bitcoin, especially in the beginning, but they might still be interested in authentication. This could be a "gateway drug" to the ecosystem for sceptics. 

That's good suggestions. Thanks for the feedback!

Lightning login app - good or bad idea?

I think this is a good idea!

LN tech has and will have a lot uses, we should not necessary pack them all together.

Have an indipendent vertical login app make sense because every record (wallet) can have additional infos (like you did) and a separation of money/logins could also be welcomed from a security/privacy point of view.

I sugget to find a in-app way to promote the money side, for example with an informative section, a selection of resources/wallets and some ideas on how to to manage identities and wallets, with pro and cons,  in a unique app or with multiple tools.
