> increases the odds of all your logins being compromised in one swoop Yes... but if someone has access to your 1Password account, they most likely gained physical access to or otherwise pwned your computer. Sure, it's slightly easier for an attacker to do that than to get 2FA tokens off your phone, if that's where you keep them. So the increased risk of using 1Password for 2FA (given you're already using 1Password for passwords) would be roughly quantified by taking the risk of computer pwnage and subtracting the risk of phone pwnage given they already pwned your computer -- not much in my opinion, if you're reasonably security-conscious on your computer. Note that I'm ignoring the risk of 1Password's encryption being broken or insider threat at AgileBits, which in my opinion is vanishingly small at present.
