Getting Started

Create your first encrypted QR backup in under a minute.

What is W2QR?

W2QR encrypts your BIP-39 seed phrase (mnemonic) into a QR code. The QR code is your backup — print it, save it as a file, or store it in the cloud. When you need your wallet, scan the QR and enter your password.

Unlike traditional encryption, W2QR uses honey encryption: every password produces a valid seed phrase. An attacker who steals your QR cannot tell which password is correct — they get millions of plausible wallets.

No wallet app required

W2QR is not a wallet — it is a protection and recovery tool. Your encrypted QR works independently of any installed app. You do not need MetaMask, Coinomi, Trust Wallet, or any other software to create or restore your backup.

Once you decrypt your seed phrase, you can import it into any BIP-39 compatible wallet of your choice — or use the built-in W2QR wallet directly in your browser.

Create an Encrypted QR

  1. 1
    Go to Create > New Encrypted Wallet — enter your 12 or 24-word seed phrase, or generate a new one.
  2. 2
    Choose a strong password — or use the Strong Password Generator to derive one from a memorable phrase. Argon2id makes each guess expensive for attackers.
  3. 3
    Save the QR code — download as PNG, SVG, or JSON. Print it and store it like a hardware wallet recovery sheet.

Everything happens in your browser — your seed phrase is never sent to any server.

Restore Your Wallet

  1. 1
    Go to Open Wallet — scan your QR code with the camera, upload the image, or paste the data.
  2. 2
    Enter your password — decryption runs in your browser using WebAssembly.
  3. 3
    Use your seed phrase — view it on screen, copy it, or open it directly in the W2QR wallet. Import it into any compatible wallet app.

How it works

W2QR uses a single creation flow. Every wallet is encrypted with your password using honey encryption and Argon2id key derivation. There is no mode selection step.

  1. 1
    Enter your seed phrase — type your 12 or 24-word mnemonic, or generate a new one
  2. 2
    Set a password — Argon2id makes brute-force expensive; honey encryption means every password decrypts to a valid mnemonic
  3. 3
    Save your encrypted QR — download, print, or store it digitally
  4. 4
    Optional enhancements — add Google Drive backup, biometric protection, Strong Password with password QR, plastic cards, or Shamir split for distributed custody

Alternative starting points

Plastic card: If you have a pre-printed W2QR plastic card, go to Activate Card to scan it and set up your wallet with password encryption. You can also create a password QR card from the Strong Password Generator — print your wallet QR and password QR on separate cards for easy, secure access.

Google Authenticator (TOTP): After creating your encrypted QR, you can optionally add Google Authenticator as a second factor. This lets you unlock on any device by entering your password plus a 6-digit code from your authenticator app.
