I like yubikeys since it means I don't have to pull out my phone. totp on the laptop also works well enough.
sms based 2fa is the worst. it seems like to me every ceo and other non-technical c-level person I've known personally loves sms based 2fa though because they can't figure anything else out.
They like it because it’s cheap and easy. They pay a phone provider for the 4 digit phone number and type in a script to generate a random code and text it. There is no oversight or maintenance.
Pairing with an Authenticator app is easy, but a little more work. Pairing with a mobile app can get a little tougher and require development plus maintenance in making sure the app cannot be spoofed and works with updates. Using a physical drive for 2FA is a pain in the ass to set up. From a business standpoint, 2FA only needs to work enough to remove liability from your business. If someone spoofs your cellphone number that’s on the phone provider not them so that’s enough to remove liability
Phone numbers can be spoofed and calls can be redirected. Or, even better, conditional call forwarding is supported by most carriers. It can be set up and you’ll never know. Then they get the phone call and not you
Right but the point they're making is it's a lot easier for a third party to intercept a code that has to be sent to you than it is for them to get the code from an authenticator app since they're generated on your device. At that point you pretty much need physical access to the phone.
im osrry so a hacked device would not show the authenticator code? I really don't see the difference here. Again its not each bit being so un breachable as much as they would have to have to breach both parts. I really don't think its taht easy to redirect all the calls that are supposed to go to my phone.
I don't think thats necessarily true. If diverting phonecalls were so easy there are a bunch of reasons outside of two factor attacks that it would be used for.
you seem to be limiting it to sms. you do realize your talking to a person who mentioned microsofts option to call you and you hit pound. They actually have an app where you input a two digit number and if anything I would have liked them to expand the phone call function with that. Anyway I was not speaking about sms but I still feel the vulnerabilities are overblown when used with a good password.
