You are correct. I just check and the current web version now includes TOTP (2FA secret key) support. I am not sure if passkey support is there or if this functionality is available on all platforms, but it looks like the delta between 1Password and ProtonPass is becoming near insignificant.

I am a Proton and 1Password user. For now, I still prefer 1Password over ProtonPass. The only thing really keeping me from fully adopting ProtonPass is the lack of a Linux client (last I checked) and the excellent 2FA integration that was recently added to 1Password. Last I checked, Proton does not have that yet.
