Note about this forked version: this is identical to the upstream version from which it is forked, except that under the "QR Codes" javascript below (which is marked in boldface as having been changed from the original), a single line has been added which exports the data URI of the QR Code as well, so the QR code can be saved or recreated without re-running the script.

Since you can't save the QR code images from the chrome app debugging console, I added console.log('qrcode_dataURL',qr_url); to the console logging lines before console_image(qr_url, qr_size);, so it'll save a data URI along with the other information in the log file that you can use to re-display the qrcode images at a later time.

For instance, if it gives you qrcode_dataURL data:image/png;base64,blahblahblahblahblahblah, you can either paste data:image/png;base64,blahblahblahblahblahblah in the browser address bar as-is to see the QR code, or, in an HTML file as <img src="data:image/png;base64,blahblahblahblahblahblah"> to create an HTML file you can open in a browser to display the QR code.

This way you can save the QR codes for later without needing to run this script again to regenerate them.

Any discussion of this gist other than specifically about the QR code data URI should occur on the upstream gist at https://gist.github.com/gboudreau/94bb0c11a6209c82418d01a59d958c93

Generating Authy passwords on other authenticators

*update: TBC, but this new might affect how easy it is to use this technique past August 2024: Authy is shutting down its desktop app | The 2FA app Authy will only be available on Android and iOS starting in August

This gist, based in part on a gist by Brian Hartvigsen, allows you to export from Authy your TOTP tokens you have stored there.
Those can be "standard" 6-digits / 30 secs tokens, or Authy's own version, the 7-digits / 10 secs tokens.

Since the Authy "desktop" app is a Chromium-based web-app, we'll use the Developer Tools provided by Chromium to execute Javascript code that will export the tokens in JSON or as QR codes. You can then import or manually add those in you preferred application.

Important: If you have any accounts that use the Authy TOTP SDK (eg. Gemini, Twitch, Sendgrid, Twilio, ...), you can NOT delete your Authy account, even after migrating your TOTP tokens to another software! If you do, you could be locking yourself out of all the accounts that require Authy specifically! Your only option here would be to go in those accounts, disable Authy 2FA, and enable another 2FA method. More details here.

Detailed How-To

Install Authy desktop app, version 2.2.3 (the more recent versions won't work)

Note: If you are prompted to update, do NOT do it; the latest version doesn't support --remote-debugging-port needed below.
macOS

Download and install this file: https://pkg.authy.com/authy/stable/2.2.3/darwin/x64/Authy%20Desktop-2.2.3.dmg
MD5 hash: ab7e4ae5b88cb71f84394df6989950aa

You can use the following command in Terminal, before launching Authy Desktop, to disable auto-updates:
```
mkdir -p ~/Library/Caches/com.authy.authy-mac.ShipIt ; rm -rf ~/Library/Caches/com.authy.authy-mac.ShipIt/* ; chmod 500 ~/Library/Caches/com.authy.authy-mac.ShipIt
```
Windows

Download and install one of those:
64-bit: https://pkg.authy.com/authy/stable/2.2.3/win32/x64/Authy%20Desktop%20Setup%202.2.3.exe
MD5 hash: efd176d89b280809b9f84fda9ba50840
32-bit: https://pkg.authy.com/authy/stable/2.2.3/win32/x32/Authy%20Desktop%20Setup%202.2.3.exe
MD5 hash: d66d63abb482523ad27dfe676e249fff

Authy will start after installation. Close it ASAP.

To prevent auto-update, go to the %LOCALAPPDATA%\authy folder, and delete Update.exe. Delete the app-2.4.2 folder, if it exists. (The version number will probably be a higher number.) In the app-2.2.3 subfolder, delete Update.exe.

Or, after the app updated, you can change your shortcut to execute "%LOCALAPPDATA%\authy\app-2.2.3\Authy Desktop.exe" --remote-debugging-port=5858 and change the Start in to %LOCALAPPDATA%\authy\app-2.2.3
Even after an update is installed, 2.2.3 is still installed.
Linux (using snap) (recommended)
```
cd /tmp
curl -Lo authy.snap https://api.snapcraft.io/api/v1/snaps/download/H8ZpNgIoPyvmkgxOWw5MSzsXK1wRZiHn_18.snap
if ! echo a488d3f3c06672a78f53da144f4325d8 authy.snap | md5sum -c --status ; then
    echo "Error: invalid MD5 hash"
else
    unsquashfs -q -f -d authy-2.2.3 authy.snap
    cd authy-2.2.3/
fi
```
Linux (using flatpak) (alternative method if snap above doesn't work)
```
flatpak install flathub com.authy.Authy
# Update to the 2.2.3 commit (found this commit using: flatpak remote-info --log flathub com.authy.Authy)
sudo flatpak update --commit=83c0df0dd48bbb6ad851f5cc62d6e0836e56e499c7a79041241809f8296e65cc com.authy.Authy
# Optionally, if you want to export a JSON file, give access to Authy to your Home folders:
sudo flatpak override --filesystem=home com.authy.Authy
```
Start Authy desktop app, but add the --remote-debugging-port=5858 parameter to the command-line:

macOS

From Terminal.app: open -a "Authy Desktop" --args --remote-debugging-port=5858

Windows

Right-click the Authy desktop shortcut, and in the Target field write --remote-debugging-port=5858 at the end. Then click OK. Double-click the Authy desktop shortcut.

Linux

From a terminal: ./authy --remote-debugging-port=5858 (if you used snap)
or flatpak run com.authy.Authy --remote-debugging-port=5858 (if you used flatpak)
In Authy, Log in so you can see the codes being generated for you.
If you have some codes that show a padlock next to them, you will need to enter your Backup Password before continuing below, or those codes won't be exported correctly (decryptedSeed will be empty).
Open the following URL in Google Chrome (or any Chromium-based browser): http://localhost:5858
Click the Twilio Authy link in that webpage.
In Chrome Developer Tools top navigation bar, go in the Sources tab (if you don't see it, click >> to expand the full list), then select the Snippets sub-tab (tabs on the second line; again, click >> to expand the full list), and finally choose + New snippet.

Careful here: do NOT open the Chrome Developer Tools like you normally do. When you go to http://localhost:5858, and click the Twilio Authy link in that webpage, it will show you Developer Tools for the Authy app. This is where you need to work. Here's a video that shows you exactly where you need to be, when you paste code: https://youtu.be/nArCf8iEqlw
If you'd like to ensure the code below doesn't send anything to a remote server, you can disconnect from the internet now.

In the snippet editor window that appears on the right, paste one of the following code options:

Simplest

This is the simplest form there is, and it will simply show you an object for each code you have in Authy. You can use that if you're scared to run complicated code you don't understand (i.e. the other options below).

appManager.getModel().forEach(i => console.log(i))

Simple

This is still quite simple, but makes it easier to copy-paste everything out of the console in one operation.

appManager.getModel().forEach(i => {
   console.log("{");
   console.log("    createdDate: " + i.createdDate);
   console.log("    accountType: " + i.accountType);
   console.log("    name: " + i.name);
   console.log("    originalName: " + i.originalName);
   console.log("    decryptedSeed: " + i.decryptedSeed);
   console.log("}");
})

QR codes [NOTE: THIS IS THE SECTION WITH CODE CHANGED FROM THE ORIGINAL IN THIS GIST FORK.]

This version will output QR codes that you can scan using another app, from your mobile device.
If you uncomment the last line, you will also get a .json file that contains your tokens (name, secret & URL).

All your Authy tokens will be displayed in the Console at the bottom; either copy-paste the TOTP URI, or scan the QR codes.

Export to Bitwarden JSON - Simpler version

From @oetiker (ref):

[...] you will get a dump in json format which you can directly copy/paste into the bitwarden import tool. Since Authy does not contain complete login information, I would suggest to create a new folder for the import, so that you can then merge the TOTP tokens into the actual login entries.

let x = []; 
appManager.getModel().forEach(i => {
  if (i.originalName && i.decryptedSeed) {
    x.push({
      type: 1, 
      name: i.originalName,
      login: {username: i.name, totp: i.decryptedSeed}
    })
  }});
  console.log(JSON.stringify({ encrypted: false, items: x})
);

Export to Bitwarden JSON - Advanced

This code can be used to save your tokens as a JSON file, for example to import into Bitwarden.
It will create an Imported from Authy folder, and import your TOTP codes in there.

Export to JSON format (2FSA / Raivo)

@brenc says (ref):

I have modified the snippet to produce a Raivo OTP format export file that can be directly imported into 2FAS Auth (and of course Raivo and others I'm sure):

// Based on https://github.com/LinusU/base32-encode/blob/master/index.js
function hex_to_b32(hex) {
  let alphabet = "ABCDEFGHIJKLMNOPQRSTUVWXYZ234567";
  let bytes = [];
  for (let i = 0; i < hex.length; i += 2) {
    bytes.push(parseInt(hex.substr(i, 2), 16));
  }
  let bits = 0;
  let value = 0;
  let output = "";
  for (let i = 0; i < bytes.length; i++) {
    value = (value << 8) | bytes[i];
    bits += 8;
    while (bits >= 5) {
      output += alphabet[(value >>> (bits - 5)) & 31];
      bits -= 5;
    }
  }
  if (bits > 0) {
    output += alphabet[(value << (5 - bits)) & 31];
  }
  return output;
}

// from https://gist.github.com/gboudreau/94bb0c11a6209c82418d01a59d958c93
function saveToFile(data, filename) {
  if (!data) {
    console.error("Console.save: No data");
    return;
  }

  if (typeof data === "object") {
    data = JSON.stringify(data, undefined, 4);
  }

  const blob = new Blob([data], {
    type: "text/json",
  });

  const e = document.createEvent("MouseEvents");
  const a = document.createElement("a");
  a.download = filename;
  a.href = window.URL.createObjectURL(blob);
  a.dataset.downloadurl = ["text/json", a.download, a.href].join(":");

  e.initMouseEvent(
    "click",
    true,
    false,
    window,
    0,
    0,
    0,
    0,
    0,
    false,
    false,
    false,
    false,
    0,
    null
  );

  a.dispatchEvent(e);
}

const items = appManager.getModel().map((i) => {
    let secretSeed = i.secretSeed;
    if (typeof secretSeed == "undefined") {
        secretSeed = i.encryptedSeed;
    }
    const period = i.digits === 7 ? 10 : 30;
    const secret =
        i.markedForDeletion === false ? i.decryptedSeed : hex_to_b32(secretSeed);
    const [issuer, rawName] = i.name.includes(":")
        ? i.name.split(":")
        : ["", i.name];
    const name = [issuer, rawName].filter(Boolean).join(": ");
    
    return {
        account: name,
        algorithm: "SHA1",
        counter: "0",
        digits: `${i.digits}`,
        iconType: "",
        iconValue: "",
        issuer: name,
        kind: "TOTP",
        pinned: "false",

});

Export to unencrypted JSON format (Aegis)

@dvshkn says (ref):

Based on the snippet by @brenc, here is a version that exports to unencrypted Aegis JSON format.
To keep things short this version only dumps the JSON to the console instead of triggering a file download.
In Aegis (on your mobile device) use Settings > Import & Export > Import from file and select Aegis file format to import the JSON file.

// Based on https://github.com/LinusU/base32-encode/blob/master/index.js
function hex_to_b32(hex) {
  let alphabet = "ABCDEFGHIJKLMNOPQRSTUVWXYZ234567";
  let bytes = [];
  for (let i = 0; i < hex.length; i += 2) {
    bytes.push(parseInt(hex.substr(i, 2), 16));
  }
  let bits = 0;
  let value = 0;
  let output = "";
  for (let i = 0; i < bytes.length; i++) {
    value = (value << 8) | bytes[i];
    bits += 8;
    while (bits >= 5) {
      output += alphabet[(value >>> (bits - 5)) & 31];
      bits -= 5;
    }
  }
  if (bits > 0) {
    output += alphabet[(value << (5 - bits)) & 31];
  }
  return output;
}

const items = appManager.getModel().map((i) => {
  let secretSeed = i.secretSeed;
  if (typeof secretSeed == "undefined") {
    secretSeed = i.encryptedSeed;
  }
  // @brenc: All of my Authy accounts have a 20 second period. Not sure why
  //         this was 10.
  const period = i.digits === 7 ? 20 : 30;
  const secret =
    i.markedForDeletion === false ? i.decryptedSeed : hex_to_b32(secretSeed);
  const [issuer, rawName] = i.name.includes(":")
    ? i.name.split(":")
    : ["", i.name];
  const name = [issuer, rawName].filter(Boolean).join(": ");

  return {
    type: "totp",
    // NOTE: Aegis generates a fresh UUID if we skip this property
    // uuid: null,
    name,
    issuer: name,
    icon: null,
    info: {
      secret,
      algo: "SHA1",
      digits: i.digits,
      period: period
    }
  };
});

// Example from https://github.com/beemdevelopment/Aegis/blob/master/app/src/test/resources/com/beemdevelopment/aegis/importers/aegis_plain.json
const aegis_data = {
  version: 1,
  header: {
    slots: null,
    params: null
  },
  db: {
    version: 1,
    entries: items
  }
};

// dumps entries to console in Aegis JSON format
console.log(JSON.stringify(aegis_data, undefined, 4));
