For most people, there's a sweet spot between security and convenience. Being able to open Proton Pass with a physical credential like a (Yubi/Solo/Nitro/etc) USB key, or something like Apple keychain (unlock with a fingerprint, would be a big Improvement, and certainly over a PIN. Certainly more convenient than having to use the password used to secure the whole account whenever it logs out and not be able to store it in Proton Pass for that purpose (shall I write it on a post it note?). If it is possible to log in to Proton's website with a Passkey, surely it should be possible for Proton Pass too?
