Passkeys are utter trash in implementation but the underlying concept is good

npub login is flawed because it can’t support multi identity and is non-private by design 

 And also they don’t use obscure shit like BIP304 signatures so they can be put onto a secure element 

 All the "hardware wallet" implementations for Bitcoin show that you can make a secure element for BIP340 just fine. 

 Specialized SEs != TPMs in computers, SEs in phones, etc 

 Ah yes correct. 

 BIP340 are Schnorr signatures?

Section: C.4.3 EC Schnorr

"If a TPM supports ECC, it should support the TPM_ALG_ECSCHNORR scheme."
