    It’s been known for years that SMS-based 2FA is terrible, terrible security. The sites that use them have no interest in their users’ accounts’ security: all they’re interested in is harvesting their phone numbers.

        2FA is great. It’s the best tool there is against impersonation and account takeovers.

        But it’s only great PROVIDED

        1. It’s a real, proper second factor like a hardware token or - less great but okay - a “secure” cellphone app. When it’s a totally insecure factor like SMS, 1FA is preferable.
        2. It’s not such a PITA that you hate using it.
        3. When it’s a proprietary app from one of the big data sonsaremoved, it’s also an app to spy on you and your activities.

      SMS is fine for 2FA, as long as you can’t use it for anything else, like a password reset.

      Once the SMS is used for account recovery, it’s now 1FA with a terrible security hole.

      If you have complex, single use passwords, and have SMS 2FA, then it’s pretty ok. Not the best security, but at least better than a most.

      Obviously offline time based passkeys are better for the 2FA, but typically the real problem is how to get into an account if you’ve lost one part of your login.

        Oh yeah? Post your bank customer number and your telephone number on here and see how fast your account gets drained without you even getting a single confirmation code SMS.
