I quote myself from a different comment:
> I just needed to think of the scene from the Simpsons, where Mr. Burns and Smithers go all through the security checks and in the end, there is a flimsy open backdoor, where a stray dog entered the room. All security in the front doesn't matter, if the backdoor is not secure at all and until the backdoor is that unsecure, I'm not willing to add money and time, to make the front door more secure.
The phone argument lacks a bit. Accessing the TOTP App and the password manager do require a separate authentification, to get encrypted. Sure if they snatch my phone away, when its fully unlocked, including my password manager, they have access for a limited time. They need to be fast enough, until I can remotly lock it or until it automatically locks itself. Android phones can now detect when they are stolen. Either by the movement or when it goes offline. The latter I tested and it's not instant, but you still don't have long.
I don't think about potential backdoors. If there is no known backdoor, then I deem it save. Sure they also could me to unlock the phone. This would be xkcd 538. And this applies to any security.
Adding more security and inconvenience doesn't make sense to me, so long the backend is shit. So far a few big companies did screw up hard in their backend and dozens of smaller sites do some bad stuff, that it doesn't really matter how strong your login is. Here I reference back to my quote.
In a closed system, like a company, this added security makes sense, as they usually control the backend as well. If my CEO would send me a text request to reset his logins, I would call him or walk to his office, and ask him directly. Sure with AI, they could impersonate his voice but I don't think they can impersonate his way to speak.

Well Passkeys are a good step to enhance security and remove potential backdoors from companies for one. As you have your private key that cannot be easily imitated and is checked by the company that you use. And generally speaking, your phone can be attacked via software without even having physical access. So if your phone is infected they gain access (at some point during usage) to both your password manager and your 2FA. It is just never a good idea to have multiple thongs in one place. On a side note, with physical access to one of your devices for a longer time, most things can be accessed by a malicious actor.
