      Folks, the only reasonable path forward is physical tokens like security keys. If you are a congressional campaign or an NGO/org who should be concerned, ping me and I will connect you with people who will give you some and train you how to use them (super easy). It's easy!https://twitter.com/gavinsblog/status/1024713428211048448 …

      Much better than SMS, but if you are a high-value target, it can be phished. A Yubikey costs lests than $20; can be used in many services (Gmail, Facebook, etc.) and works fine! Can't be phished AT ALL.

          Used as FIDO authenticators, Agree. But many Yubikeys can also be used in a legacy one-time password mode, which can be phished.

          Where can I get a Yubikey for less than $20? I found they're at least €40 and a lot more here in Belgium/Netherlands.

          I’ve been working on finding new payroll vendor for my company, only three (out of six) offer a 2 factor solution. Of the three that offer it, all use SMS or EMAIL (🤯, email?!?!?) for second auth. A real travesty.

          If the hardware token is generating a code, it is phishable in the same way that an app token is. The number has to be transmitted at some point. Having signed authentication codes is the only way to prove it is you.

          I bought a Yubikey a while ago, but it seems I need to be using Chrome for the key to work. I always use Safari. Do I really need to switch to Chrome, which I really don't want to do?
