Is the push for 2FA really about security?

    I noticed an interesting coincidence.
    The push for 2-factor-authentication came about around the same time Chrome, Firefox, and other browsers started restricting 3rd party cookies.
    Also most of the sites require a cell phone number, rather than a number of other options for 2FA.

    I have to wonder if this concern about password security is really about security, or obtaining a unique identifier (the phone number) that they can use to track you and can be used to compile data on interests for advertising data now that the 3rd party cookies are being blocked. They don't need or care about your name, just that this web entity with this phone number visits these sites and sells it to data miners for various purposes.

    2FA and advertising are not normally linked in any way. Also, data collection is under a number of strict rules at this point, so no legitimate website could just use phone numbers for a purpose other than stated. Note, phone numbers usually aren't used or stored by the websites themselves, but by some of the 2FA apps, e.g. Authy.

    Also, setting up 2FA with a phone number / cell phone usually isn't the only way to do it, but it's often the most convenient and reliable. I've had to turn on 2FA for all logins on the Codex about 2 years back as we've had a number of incidents where people's forum logins were exploited (as they used the same login details on other, hacked sites) and the attackers then initiated mass post/thread deletion and editing sprees, which caused a number of issues and wasted our time constantly doing cleanup.

    As someone who designs services with 2FA, I can tell you that there's no connection between the two, at least not on any mainstream service. Also, most of us prefer not to use SMS as the primary means of providing 2FA for our customers because it's notoriously unreliable. The fact that browsers started blocking 3rd party cookies and websites started pushing for 2FA stems from the same privacy/security concerns, which is why they both coincidentally appeared at a similar time.
