By storing your passwords and otp in the same place it becomes 1 factor authentification
Technically yes if my vault gets compromised I would be fucked. I have it firewalled tho and only accessible from home (or VPN to home). So should be pretty secure. I used google authenticator but found it a major pita (can’t even search entries on Android, wtf?). If they make this more user friendly I’ll gladly switch back to a seperate OTP store.
Not really as you’re still protected from password breaches, which is most likely to happen anyways, especially if you self host.
If you’re actively being targeted for your bitwarden password, you likely have bigger problems
To set a scene, you awake in the middle of the night because your phone is making noise. Blearily you unlock it, glance at a prompt, and then approve a login and fall back asleep. The intruder now has access to your password manager!
They attempt to log into your bank and drain your life savings, but despite having your password it sends another prompt to your phone. This time, you wake up enough to realize something is wrong. This time, you deny the prompt.
The entire second paragraph cannot happen if your MFA is a single factor. Don’t store MFA in your password manager!
