I wonder how nobody sees the elephant in the room.
2FA by SMS is terribly insecure. Numerous security researchers recommended never using it. Using phone numbers as primary authentication mechanism is insecure and never should be used. Phone numbers can be spoofed, SMS messages can be intercepted, SIM port attacks can and will happen. If your email or banking accounts depend on 2FA by SMS, especially when SMS can be used to reset the password — disable it now. Avoid it like plague.
More than that — if your account has significant value that you absolutely can’t afford to lose, you shouldn’t use _any_ 2FA services linked to your phone, at all, including Google Auth. Your phone can be lost or stolen anytime. Use a dedicated device which you don’t take with you all the time.
- therealmarv 7y agoI know SO many real banks which still use 2FA by SMS.
- klardotsh 7y agoAnd it was a hell of a fight to even get _those_. Alliant Credit Union, for example, only just rolled out SMS-based 2FA in the past ~year. No TOTP/U2F/FIDO* options at all (in fact, according to https://dongleauth.info/ https://dongleauth.info/, exactly zero major banks/CUs in North America support anything better than SMS or TOTP). When I can lock my GitHub account more securely than my _money_, it's a bit (read: lot) depressing.
