However, despite what the headline says, this 2FA does not appear to be mandatory.
Under the heading: "Who is excluded from this account email-based new device verification?"
> Users who opt-out from their account settings, to which an option will be added, are excluded.
I'm on 1Password and it's basically a 2FA setup there too: to register a device, you need to have the master password (what you know) and the secret key (what you have, randomly generated at vault creation). Losing my phone isn't a big deal because I have 1Password on multiple devices, each with a copy of the secret key, so there's pretty good hedging there.
I also carry a physical Yubikey, which grants me passwordless access to my email account (assuming I know the PIN to unlock the hardware, which I do). That's probably overkill for most people, but that's another layer of hedging too.
Given that only I have my master password I don't see what's wrong with it.
A second factor makes it extremely unlikely that one slip up results in a complete compromise of your vault.
Even easier: What if someone beats you with a stick until you unlock your password manager?
Security is always a compromise around a lot of assumptions about threat model, usability, etc.
Nudges are a great way to increase overall user security with almost no drawbacks, but ofc ultimately things like this always have to be user choice.
All my high security accounts themselves are protected by 2FA and in some cases 2+ factors (such as my bank).
2FA on a password manager is useless. I'm going to end up entering phone codes multiple times for a single login and that will drive me away from using the password manager.
2FA for setup doesn't strike me as too onerous. It only happens once per device, after which you're free to rely on just your master password or even biometrics.
Exactly because of the fire risk, I set a policy for myself that all passwords should be somehow recoverable only from something that I know. However, I don't meet this policy at the moment.
I use Bitwarden 2FA with my phone, but I have backup codes stored in a fireproof safe with my other important documents.
That hopefully would only happen in extremely rare conditions, but that's not a risk everyone would take. Especially in area where losing your home is a very real risk, and you'd be hanging to your data by a string while facing an otherwise already challenging situation.
The 2nd factor is only needed when it's new or occasionally in other cases. I don't know why you say it adds lots of friction, unless you are frequently signing into new devices.
And as a failsafe a printed backup code is pretty important.
This is doubly true because Bitwarden has not been consistent at only asking for 2FA on brand new devices, so it's not even just me that I have to worry about locking the car doors.
Removing the friction of many passwords is the whole reason a password manager is good in the first place!
It seems like every IT person needs this lesson reiterated to them, at least once a year...
At the very least split your providers - no one manager has all my passwords and 2FA codes.
Even without, accidentally getting one password leaked is a lot more likely than two. For whatever reason, shoulder peeking, keylogger, wrong input field, brute forced, and so on.
In my mind the email is the second worst 2FA since it's used for registering everywhere on the web and more prone to be compromised. Phone number is the worst.
