If my primary device is compromised and my master password is compromised and the device that I use for second factor authentication into my password manager is compromised then the secondary device that I could use for 2fa codes is compromised. For most normal people, storing second-factor codes in Bitwarden alongside passwords is marginally worse at worst, and inconsequential at best.

Yes, if you use a bad password manager that is fundamentally flawed (like LastPass) then all bets are off but that's not an argument against the principle of storing 2fa codes alongside passwords in a password manager.

I doubt there's a single Bitwarden user on earth who has ever suffered a security incident because they store their 2fa codes in Bitwarden, that's how inconsequential this risk is.
