    I realized long time ago that I don’t want my 2FA be tied to my phone number. And then i found you can’t export your data from Authy because they know they are scummy fucks and don’t want to anyone to leave

      You can, though. But not through their app. Someone reverse engineered their protocol and wrote a program that connects like a new client, which you then approve, and it dumps all your random seeds into a text file. I then put them all into Keepass.

      Edit: Unfortunately, the author has deprecated the project as Authy has added some attestations to their API, seemingly for this exact issue. https://github.com/alexzorin/authy?tab=readme-ov-file

        People keep acting like Authy is betraying them by not having an export feature, but why exactly are you leaving Authy to begin with? Because they are a security risk?

        You’re gonna leave Authy a copy of your seeds? That defeats the purpose.

        Re-key your MFA codes on the way out. Security isn’t necessarily convenient.

      Exporting data from a 2FA app sounds like the opposite of secure. Not to mention you don’t want your 2FA codes on Authy (or any other 2FA app) to remain valid if you’re not using it.

      When I switched from Google Authenticator to Authy years ago, I went through each 2FA-enabled account one by one to disable 2FA and then re-enable it using Authy. It’s a long process depending on how many accounts you have 2FA enabled on, but it’s worth it.

      Reading the OP, looks like it’s time to generate new keys for all my 2FA accounts.

        If you can’t export / save / transfer codes then you need to regenerate all your 2fa codes every time you switch to a new device.

        2FA doesn’t need to be infallible, it just needs to be a second factor.

    Companies need to stop using Authy. It’s stupid and pointless when we have a open alternative such as the one used by Google Authenticator or Aegis.

      I started using Authy instead of GA because every time I changed the ROM on my phone I would lose all codes, because I would forget every time.

        Use aegis, export the keys and then reimport them every time you switch. Trusting your second factor to a cloud is a disaster waiting to happen.

        If you want to get fancy setup your own cloud server (nextcloud, Seafile, owncloud etc) and set the backup folder for aegis to the self hosted cloud for easy restore every time you switch ROMs.

        I’ve started putting mine into my Bitwarden vault as well as Google auth, mainly because I’m a bit paranoid I’ll wind up locked out of something by trusting a second factor too much

          With password recovery you shouldn’t be getting locked out of anything. I don’t see this being a risk.

    Does anyone have a suggested alternative for authy? (Please read the whole post before responding)

    I’d love to go with an open source solution as I’ve done with my password manager, but that doesn’t seem possible with one of my big requirements:

    Scenario: I’ve had my phone robbed abroad and managed to buy a new one and loaded my ESIM back into it—I need to recover access to my 2 factor database via SMS so I’m able to log into my cloud storage and access my password database.

    At this point I’d probably be happy to host a service myself on something like AWS and use SNS for this requirement, but I’m not sure anything like that exists ready to go. I’m not particularly interested in rolling something myself for this.

    I’d be dubious of jumping from one closed source product to another, but if there’s a particularly good option I’m all ears, I’ve been otherwise happy with authy for about a decade now, but this plus the retirement of the desktop app have me looking elsewhere.

    Edit: added emphasis

        I’ve looked into this before and unfortunately it doesn’t support the SMS requirement I have in my deal-breaker scenario—do you know if this has changed and can point me to the docs regarding it?

          Oops, missed that part. Not that I know of, though SMS is a terrible way to do 2FA. It annoys me so many businesses and banks use it.

            I agree it’s much worse than using a modern OTP app, but I need a way to access my OTP database when the only form of digital identity I have access to is my phone number.

            Authy currently supports this scenario for me (with a load of checks, it doesn’t happen instantly), so I would require a like for like replacement

              Bitwarden has a 2FA recovery code possible so you could use a unlabeled hard copy of the code. It cycles after every use so it would get you one recovery and doesn’t use SMS so it’s immune to SMS shenanigans.

                That’s potentially a solution then, as I guess in order to buy a new phone I would need to have not lost my wallet too at least, so I guess I could keep those items together for equivalent recovery possibility

                Okay that may be a goer, I’ll look a bit more into it, thanks!

      Buy a few (at least 2 for a backup) yubikeys.

      Much more secure.

      You can store the TOPT codes on them, but then you can also do all the higher security things too.

      No one’s breaking into your Google account if you secure it with those keys and remove the sms backup method unless they’ve physically stolen the yubikey

      My passwords are safe.

      No, they’re really not. No matter how good your password is, it can absolutely be compromised. If you use a password manager, just look at how often sites tell you that you “forgot” your password, despite knowing you haven’t.

      Use 2fa for things that are absolutely vital. Whether you use it for your Blizzard account or Steam account is less important. (Though I’m pretty sure Blizzard has leaked passwords at least once, many years ago.)

          For a few months, I had been getting emails from booking.com saying that I had forgotten my password. Probably scammers with my Gmail username futilely attempting to use the forgotten password link to get at stored payment info. Once I set up 2FA on the account, the emails stopped.

    ‘hacked’. Eh. There was an API endpoint left open that allowed them to basically just spam it with no rate limiting. They used the lack of a rate limit to just pull the data out of the API that it was made to produce.

            They did not do it by manipulating code. This wasn’t the result of a code vulnerability. If you leave the door wide open with all your stuff out for the entire neighbourhood to see, you can’t claim you were “broken into”. Similarly, if you don’t secure your endpoints, you can’t claim you were “hacked”.

              Lack of rate limiting is a code vulnerability if we are talking about an API endpoint.

              Not that discussion makes any sense at all…

              Also, “not securing” doesn’t mean much. Security is not a boolean. They probably have some controls, but they still have a gap in the lack of rate limiting.

                It is a vulnerability, but exploiting that vulnerability is not generally considered by security experts to be “hacking” in the usual meaning of that term in academic settings. Using an open or exposed API, even one with a sign that says “don’t abuse me”, is generally not considered hacking.

        Exploit. The system worked as intended, just without a rate limit. A hack would be relying on a vulnerability in the software to make it not function as programmed.

        It’s the difference between finding a angle in a game world that causes your character to climb steeper than it should, vs rewriting memory locations to no-clip through everything. One causes the system to act in a way that it otherwise wouldn’t (SQL injections, etc) – the other, is using the system exactly as it was programmed.

        Downloading videos from YouTube isn’t “Hacking” YouTube. Even though it’s using the API in a way it wasn’t intended. Right-clicking a webpage and viewing the source code isn’t hacking - even if the website you’re looking at doesn’t want you looking at the source.

          A missing rate limit is a vulnerability, or a weakness, depending on the definition. You’re playing smart without having an idea of what you’re talking about. Here you go:

          https://cwe.mitre.org/data/definitions/799.html

          YouTube videos are public, and as such it’s not really hacking. If you were able to download private videos, for example, it would be a vulnerability like “Improper Access Control”. It does not matter in the least whether you use an “exploit” in your definition (which is wrong) or “just increment the video ID”.

          The result is a breach of confidentiality, and as such this is to be classified as a “hack”.
