    I had similar issues: https://news.ycombinator.com/item?id=45451567 (including my personal domain, Dropbox; my Apple account is still MIA...)

    We've all been reduced to a passphrase.

    When I've lobbed this scenario to the security managers/employees at these companies, they all give me a really great answer:

    Q: What happens if a sitting senator gets mugged and they have their printed 2fa codes sitting in their wallet?

    A: They have a special number they can call.

    Isn't there an SMS option? buy a new phone and have them send you an OTP via SMS.

    > once you're phone is gone, you are completely over with society?

    yes, I'm waiting for the Black-Mirror episode where someone drops their phone and basically dies, can't contact anyone, can't unlock or start their car, can't get an uber, can't pay for anything, can't navigate without gps, can't log into anything etc.

      Pretty similar to how my life feels right now.

        As an old curmudgeon I recoil at any service I can't interact with sans-phone. I hardly use mine for anything.

        Just be glad your phone number is tied to your account, if you lose the number itself you are royally screwed, and basically anyone who gets your old number owns all your accounts now.

    If you don't have the authenticator backup codes and you didn't turn on cloud sync in the app, you might be out of luck.

    You can get a replacement SIM though and use it with a new phone, so the phone number recovery option should work.

      This. Can't you get your number moved to a new phone? I have never don't anything magic when upgrading my phone other than move contacts.
      • jwr 1 hour ago
        How would moving your number to a new phone help? We're talking TOTP here, not SMS "auth".
        • john_strinlai 31 minutes ago
          does google not offer a backup via sms? it's a common enough recovery flow elsewhere. (i dont use google stuff, so i am genuinely asking)
          • b112 22 minutes ago
            Any less secure backup method, means others are less secure.
            • mrguyorama 3 minutes ago
              Google actually puts effort into security for "normal" people who don't want to earn a PhD in cryptography just to have a damn free email account or watch Mr. Beast

              That's why they had powerful and effective account takeover protection even 15 years ago. The kind that will prevent the hacker from taking over your account even though they got access to all your factors, because it shouldn't take expertise to know that if you logged in from Oregon twenty minutes ago, you definitely aren't also logging in from Ecuador.

              Which of course makes it all the more stupid that your credit card company, all your medical service providers, and Facebook don't meet that absurdly low bar. Facebook will happily hand control to the scammer in Laos who got one of your factors and somehow that gave them access to change your password and recovery email

            • john_strinlai 16 minutes ago
              yes, i understand. i was asking specifically whether google has sms recovery flow, not how secure sms recovery flow is compared to other options.
    • dz0ny 1 hour ago
      Happened to me, I was able to get SMS and recovery codes, but Google still required additional verification on now lost phone :D. On the end I acutely found the phone and was able to restore access. So what they do after couple of days of failed attempts the require additional verification, lets call it 3 step.

    This is why my self-hosted Vaultwarden is my one password that I have to remember and requires no 2fa, which is the only important account that doesn't have 2fa.

    If I wake up in a bathtub missing a kidney I can still get to my passwords and 2fa sources stored with it. Some accounts require SMS (annoyingly) so I'd have to buy a phone but the auth and credit card numbers I need to do that are in Vaultwarden, too.

    I don't have good solutions now for OP (other than buy a new phone through your carrier and transfer the number). But everyone else do think through your personal DRP. Generate backup codes and put them somewhere safe, too.

      Welll yeh until a Hargrove fails on your self hosted server
      • nyx 28 minutes ago
        One of my favorite things about self-hosted Vaultwarden is that you get distributed backups for free. Every client keeps an offline copy of your entire password vault, kept in sync when the client is online.

        So for me to lose my vault, not only would my server have to get hit by a bus, but also my phone, my desktop, my HTPC, both laptops...

  • SoftTalker 2 hours ago
    You're going to have more success working with the providers of the other accounts and services rather than Google. That means a lot more legwork on your part but banks and other online services all have processes to deal with lost passwords and 2FA devices. In some cases you may have to physically go somewhere with ID and other documents.

    Consider it a learning experience.

    I'll fill out a "help my friend" form internally unless someone beats me to it (I have a 1hr meeting coming up). The gmail address in question is the same one as on your website?
    • dgunay 57 minutes ago
      That's nice of you, but I'd urge anyone with influence at Google to consider 1) many many many more people who use Google services probably don't know or run in the same circles as Googlers who can bail them out of such a scenario, and 2) these people, being much less likely to understand 2FA, are also more likely to accidentally lock themselves out. An separate class of people who know how a system works or have connections to its operators become nose blind to its terrible UX because they have access to workarounds.
      • senordevnyc 46 minutes ago
        All true, but I’m guessing the set of people at Google who can fill out that form is about 1000x larger than the ones who have the ability to influence the underlying product decisions that led to this situation.
    • ihg5000mrtnav 29 minutes ago
      Sorry to bother, but I have been without access to the account I use for my YouTube channel for months because I stupidly entered a random phone number many years ago and it is now demanding access to it. If you would be willing to fill out that form for me, I would greatly appreciate it. Account is this username at gmail. Thanks!

    This happened to me on my iPhone 8 many years ago. I reset it to let my son use it, and did not have google authenticator in mind. I had to reset each account with the providers. Now I use a cloud account to sync these. I reset most accounts with an SMS or email one time code -- which led me to remove SMS and email as recovery options from google. And, I put a code on t-mobile to prevent sim transfer.
  • wccrawford 2 hours ago
    Everything you listed, plus a recovery email option, plus backup codes, plus SMS.

    That's already a lot and anything easier would allow people to just take over accounts that they don't have a right to.

  • beej71 1 hour ago
    It's a good reminder to everyone who uses 2FA. Be sure you have multiple ways in for when your phone becomes unusable.
  • haellsigh 24 minutes ago
    I've had this issue before, and the only thing that saved me was SMS (phone number) backup. I believe Google is slightly easier than Meta to contact by phone so this should help.
  • j1elo 56 minutes ago
    Recovery is similar to leaving a copy of your door keys to a trusted neighbour (a tradition in some places, it comes in handy when someone goes out and realizes they forgot the keys inside...), so in that comparison, having a recovery email unused for 12 years feels like leaving your backup keys to a neighbor that you never saw ever again in more than a decade.

    This kind of posts are a valuable trigger for all others who are reading it. To the author: good luck, I hope you sort your situation soon! I'm now headed to check my accounts for what recovery options I left in there.

  • jeroenhd 1 hour ago
    You can add a passkey (preferably a physical one) to authenticate. You can also add a software passkey but that kind of defeats the purpose.

    Actually keeping your recovery options recent is the trick. Print out your recovery codes or store them somewhere safe. Check regularly (yearly, maybe more often) that there's a way to access your critical accounts.

    For Google, you can also grab the cheapest Android phone you can find, sign in, and maybe boot it once a month or so to keep the tokens active.

    If you've set up your account to only accept one source of 2FA and you lose thst source of 2FA, you lose your account. Same happens when you set up your account to only accept your password and then lose your password. If you lose your recovery email/2FA backup codes, you lose access, unless you're special enough to convince customer support that you are who you claim you are and not just a bot trying to hack you.

    If you've lost your account and haven't set up any recovery mechanisms, you're probably out of luck. Your best bet will be looking for an old browser session with enough trust from Google's side to get access without reconfirming your 2FA trust.

    • jakub_g 1 hour ago
      Yup, having _two_ active devices which are logged in to Google (and possibly other services that you rely on that opt you in to app-based 2FA) + with backups of 2FA is a must at this point. When I buy a new phone, I make it a "primary", and keep my old phone as "backup".

      If you're not into cloud-based password/2FA syncing, Google Authenticator supports local export/import across devices via a QR code. For passwords, I use KeePass Portable / Keepass2Android + syncing between devices from time to time through a USB-C pendrive (The source of truth KP DB is on pendrive, and both phones work off a local on-device cache).

      You don't need to have your phone stolen for things to get messed up. If your screen breaks, you can't type in a PIN anymore, can't unblock with a fingerprint, and you effectively can't access anything on the phone. ADB won't connect because screen is off, and you can't unlock / accept a new external connection etc.

        > buy a new phone, I make it a "primary", and keep my old phone as "backup".

        Sadly this is why I never end up trading in my phone. Always feels too risky to not have an overlap period.

  • happyopossum 1 hour ago
    All those times you logged in and were prompted to verify your backup email address, and when you set up 2FA and were given recovery codes, and when given the option to sync 2FA codes to another copy of the authenticator app: This Is Why.

    I'm sorry you're dealing with this - hopefully everyone else here can take it as a cautionary tale.

  • runjake 2 hours ago
    The only secret option I know of is to have a popular social media account and complain online.

    Other than that, I copy/pasted your post into Claude and it had some good ideas.

  • ezfe 38 minutes ago
    The passkey I use for Google syncs to multiple devices, so that's how I handle it. That and a backup code stored in a separate location.

    There's no way, no human contact. That's why I de-googled myself.
    • lotsofpulp 2 hours ago
      No human contact is a plus for security, as the human is the weakest link that can give up your authentication to someone that isn’t you.
      • ks2048 2 hours ago
        The human factor is walking into your local branch with your face and an ID - something that can’t be done on a large scale by bots.
        • vel0city 1 hour ago
          This has often been abused with mobile phone carriers to get SIM cards issued for targets by just knowing enough customer details. This then allowed them to intercept SMS 2FA challenges and access even more sensitive accounts.
      • mococa 2 hours ago
        Have you heard about Meta AI doing support?
        • rationalist 1 hour ago
          Only if you can log in. I am Meta Verified, but I cannot log in to get support.
      • tempfile 2 hours ago
        "I am permanently locked out of my account with no recourse" is also a security issue.

      Excellent idea... shit my house just burned down with my phone.
  • SAI_Peregrinus 2 hours ago
    The same way you recover any other deleted data for which you didn't make a backup: you don't. You eat the loss & make new accounts. Then you remember to make and test backups for the future.

    Even if they had customer support, if that customer support had a backdoor to unlock your account it would be regularly used by malicious parties to steal people's accounts & data.

    While we are on this, is there a comprehensive guide on how to "theft-proof" your iPhone? Not in the sense of preventing the theft, but rather the fallout on all our various online service access.

    Using the iPhone backup to setup a new phone is a good reminder every time that not half of the stuff comes back correctly..

  • autoexec 2 hours ago
    Man, passwords sure are nice aren't they! All you have to do is remember one because your password manager remembers all the rest of your randomly generated passwords for you and as long as you keep a backup of the password database you never have to worry about this bullshit.
    • Freak_NL 0 minutes ago
      OTP works with a password manager too. I have Authy on my Android, and Pass on my Linux computers. The second is backed up properly. This approach just means that enabling 2FA (which is mostly OTP in any case) just means registering the OTP URI in two locations instead of one.

      Additional benefit: I can generate an OTP for any service protected like this without having to get my phone from wherever it is.

  • mixmastamyk 2 hours ago
    Does your browser have the email password saved?
  • pards 2 hours ago
    Going forward, consider using an authenticator that securely syncs across multiple devices to remove the single point of failure risk.

    I use Proton Authenticator now [0]

    Authy used to do this, then they enshittified their app and bricked the desktop version.

      Google authenticator supports syncing across multiple devices.
      • kwanbix 1 hour ago
        is that new? I migrated at the time from GA to Authy and from Authy to Ente because it was not supported.
  • tamimio 51 minutes ago
    Well that’s why you should have software 2FA and even backing up the tokens so you can generate that one time code even if you lost access to your main authenticator, having your phone as the only 2FA is like having those yubikey hardware used as 2FA without making a redundant one, losing it, you lost access, which is usually known since no one would use yubikey without being tech savvy to start with, now google or other companies are turning phones as an attestation method for the crowd, you might soon in the future become citizen-less because your digital ID can only be proven in the lost phone.
  • ck2 26 minutes ago
    it's too late now but there's an app called Google Authenticator that you could have setup on alternate android devices

    your only hope to get your google account back is to convince your phone carrier to transfer your old phone number to a new phone that you control

    You were supposed to save your backup codes.
  • thrownaway561 1 hour ago
    Honestly.... This is why I have everything in Bitwarden. All 2FA runs through it so even if my phone got stolen, I could still access everything. I honestly don't understand why more people don't pay the $10 a year and just use Bitwarden.
    • patshead 38 minutes ago
      > All 2FA runs through it

      I hope that isn't true, because I sure can't think of a good way to use Bitwarden's TOTP as 2FA for Bitwarden! :)

      • vablings 16 minutes ago
        FIDO2 USB Security key -> Bitwarden (With master password) -> Every other 2FA method

        I have 3 FIDO2 USB Security keys, One I carry with my persons at all times, one that stays with my main machine at all times and an offsite backup that is sitting in a friend's server, if my house burns down, I can either physically collect the key or use USB-IP to authenticate back into bitwarden and enroll a new key. (Actually all 3 are at home right now but that's ok)

        My phone is logged into Bitwarden so even then I can recover my passwords and data in case of a serious incident immediately.

        Even if both my house and my friend's house burn down at the same time, I can still recover my data from my phone unless my phone is left in the house, all of which to say I still have the recovery phrase written down in a box somewhere in a different country

    • phainopepla2 1 hour ago
      Having your passwords and 2FA with the same provider carries some risk. If someone can access your Bitwarden account they will have full access to all your accounts.

    can you recover one of the old contact points (phone or email) for a reset code?

    I would send a paper letter to the Google legal contact. It's the only way to get escalated support.

    I agree the covenant for account recovery has been broken. Every 6 months, a new artifact is expected to access the account, without adequate preparation for the recovery.
