Hey— whatever works for your setup. Especially for those who don't use a smart phone and have one machine, it's probably a minimal loss in functionality.
> Does that mean I should add another one that I can easily avoid?
All other things being equal? Avoid it, of course. I firmly oppose letting perfect be the enemy of good in the sense that more secure is better than less secure even if it's not perfectly secure. But I also oppose it in the sense that rejecting beneficial functionality because it's not perfectly secure, especially when it's not close to the biggest or most attractive attack surface, doesn't make sense. Even when password managers' servers were compromised— LastPass, for example— I don't think anybody ever got ahold of passwords. KeePass OTOH was broken with KeeFarce and RATs are a lot more common than cloud service server breaches.
> This seems focused on the case of a dedicated attacker focused on you specifically. Id think each of us is more likely to be affected by various automated attacks that are backed by large dumps of account credentials.
Nope— If it was automated the distinction is even less significant. A script would only need to search your email for whatever specific types of logins it supported and fire off password resets. Non-email 2FA becomes even more of a hurdle without the option of social engineering it or some other human-touch fix.
Consider this. (very) Roughly, this is the market penetration for these products:
* computer: 90%+
* smart phone: 85%
* tablet: 50%
* computer, smart phone and tablet: 40%
Most people (in this country, at least,) have multiple devices. Most people have internet access. Most people aren't going to be able to manage storing and sharing passwords among their devices at all, let alone more securely than cloud storage would do it. So for most people's use cases, it would be like citing health when refusing to put a teaspoon of sugar into the cup of tea they're having with cake and ice cream.
So like I said, avoid it if it doesn't improve your life— I have no stake in your password management choice— but I will actively butt in to qualify the sentiments expressed in this thread because, a) many users, even on this site, aren't sophisticated enough to engage in the sort of cost/benefit analysis that we are, and b) to them, this conversation is unintentional FUD. Cloud-based password management is vastly superior to regular folks' existing methods. If they're put off by technically savvy people saying they're fundamentally insecure, that is the embodiment of perfect defeating good.
