yes, this is an issue with the auth and we need to come up with good interoperable solutions there. what mobile wallet are you using? 
We recently made sure that BlueWallet and Alby are interoperable there if you connect the same LNDHub account. 


Ah yeah, we also need to do something on our end, allowing users to sign in with multiple methods.

Hi! 👋 I am @gzuuus in fact, I have created this secondary account to be able to use SN from the phone because getAlby is not available for phones yet... It would be interesting to be able to use the same account
