Quick question, how do you back up a 2FA “code” to Bitwarden? Sounds like a wise thing to do for my current 2FA accounts.

2FA. No, not the fucking “we’ll send you an SMS” bullshit that is increasingly used to just highlight an active phone number for spam purposes. Proper TOTP with the code backed up to a proper service (bare minimum, Bitwarden)
Someone can steal your password and even your email account (unless you TOTP that too…). They still can’t get into your account unless you are an idiot who gets tricked into providing the 2FA key.
In a perfect world? Have your TOTP credentials in one encrypted database/Bitwarden account and your passwords in another. In reality? Just use a trusted service. I used to be a big fan of Keepass but protecting that with a yubikey (or similar) is a huge mess.

Really depends on your current tool so RTFM on that.
But when you are activating it in your account? There is a QR code you are supposed to scan. And there is almost always a button like “Having trouble?” or “Show TOTP Key” or whatever. Click that and you get a long alphanumeric string instead. Paste that into the TOTP field for Bitwarden (or Keepass or whatever) and it will generate codes for you.
Once or twice I have had to actually use my phone camera to decode the QR code so that I can manually type in the TOTP code/seed, but I think the last time I did that was in like 2020?

That said, I hate it since so much of it is dependent on a single device that can generally be opened by just applying REDACTED to the screen and doing REDACTED to narrow down the lock code significantly.
Would that work with my pin which is the equivalent of 40483770487025502574448? Or is a password better?
I think a pin like that is harder to remember for people, and even to get it using fingerprints is difficult because you cover a lot of the numbers giving false information

OMFG YEEEEEEESSSSS I HATE THOSE I’m not even super duper security focused I just love the idea of even a bot farm has to guess a code within a 30 second window
Meanwhile sms codes usually expire between a ten minutes and an hour, usually a half hour, but thats if at all
As much as I hate them they’re better than nothing :/

I doubt bruteforce has been used in one of these attacks. The service should detect a bot entering many combinations per second.
The main problem with SMS is that someone could social engineer the mobile operator support to give them a new SIM.
Probably not something you should worry too much about unless you are in any way a target, but still.

I also said way less than what I was thinking but you pretty much summarized the other half of what I was thinking with people being able to get the authenticator which is in this case the message
I also just plain don’t like them
Idk why beyond the reasons I said
