Many password managers use a biometric factor to sign in (your fingerprint, for example, using some kind of auth app if needed). This basically moves the MFA aspect to one service (your password manager) instead of having each service do their own thing. It also comes with the benefits of password managers - each password can be unique, high entropy, and locked behind MFA.

The only thing this does is replace the authentication mechanism used to unlock the vault, instead of using your master password (something you know), it uses some biometric factor (something you are), although it uses your biometric data, it’s still a single factor of authentication

I am not sure I understood you here. What do you mean by “instead of having each service do their own thing”? Each website using their own method of delivering OTPs?

I am not discrediting password managers, they have their uses, as you mention you can have unique, high entropy password on a per service basis. The only thing I am against is the password managers themselves also doubling as OTPs generators (take a look at Bitwarden Authenticator which kinda defeats the purpose of OTPs. From the perspective of OTPs it makes much more sense to use a separate application (Like Google Authenticator or Aegis Authenticator), preferably on a separate device, to generate the OTPs.

Speaking from my experience, I use my phone for biometric authentication. At least from my point of view, I see that as two factors (what I have and what I am) since the biometric authentication only works on my phone.

Basically having multiple places where codes may be generated. This way you can use one location to get OTPs instead of having them delivered via SMS or generated by a different app/service. It ends up being easier and more convenient for the end user (which of course increases adoption).
I guess this has more to do with services adopting OTP generators than sending them via SMS though.

If logging into the password manager to get the password is sufficiently secure (locked behind MFA), then I don’t see the benefit of using a separate OTP generator (aside from maybe if your password manager has a data breach or something, which should be a non-issue except it clearly isn’t thanks to LastPass…)
I’m starting to wonder if phones (or other auth-specific devices) should just become dedicated authentication devices and passwords should just be phased out entirely tbh. Passwords have always had issues because their static nature means if someone learns your password without your knowledge, that method of authentication becomes worthless. The main concern would be what happens when you lose your phone I suppose.
