Most seed phrase backup methods leave your 12 or 24 words in plain text — readable by anyone who finds them. SeedVault takes a different approach: encrypt first, then store. Your seed phrase is encrypted with AES-256-GCM in your browser (nothing leaves your device), converted into a QR code, and ready to print, save, or engrave on fireproof metal. Need to recover? Scan the QR code with your phone camera, enter your password — your seed phrase is restored in seconds.
SeedVault also offers steganography — hide your encrypted seed phrase inside a normal-looking image. A photo of your dog, a landscape, a family picture: the image looks completely unchanged, but contains your encrypted backup hidden in the pixels. Store it on a USB drive, email it to yourself, or keep it in cloud storage — nobody will ever suspect it contains a seed phrase. Whether you choose an encrypted QR code on paper, metal, or a hidden image, without your password it is unreadable random data.
Seed Phrase Encryption & Backup — FAQ
To backup your seed phrase securely: (1) Open SeedVault — 100% free, works offline, nothing sent to any server. (2) Enter your 12 or 24 mnemonic words and choose a strong password. (3) Generate your encrypted QR code — AES-256-GCM encryption, unreadable without your password. (4) Save it: print on paper, store as a file, or order it engraved on fireproof stainless steel. Store your password separately. That's it — the safest seed phrase backup possible.
Yes. SeedVault is 100% client-side — all encryption happens in your browser and nothing is ever sent to any server. The code is fully open-source and auditable. It works offline forever and uses industry-standard AES-256-GCM encryption, the same used by banks and governments.
Yes! After generating your encrypted QR code for free, you can order a laser-engraved stainless steel or titanium plate directly from SeedVault. The metal plate is fireproof, waterproof, and indestructible. Even if someone finds it, they cannot access your funds without your password.
Yes, SeedVault works with any wallet that uses BIP39 seed phrases - all major hardware and software wallets. It supports both 12-word and 24-word seed phrases for Bitcoin, Ethereum, and all other cryptocurrencies.
Steganography is the art of hiding data in plain sight. SeedVault encrypts your seed phrase with AES-256, then embeds the encrypted data inside the pixels of a normal-looking image — a photo of your cat, a landscape, anything. The image looks completely unchanged to the human eye. You can store it on a USB drive, email it to yourself, upload it to Google Drive — nobody will ever suspect it contains your seed phrase. It's encryption + invisibility combined.
Yes! You can download the standalone HTML file and use it on an air-gapped computer with no internet connection. This is the most secure way to encrypt your seed phrase. The downloaded file contains all functionality — no server needed, ever.
Yes, generating encrypted QR codes and steganographic images is 100% free and always will be. The only paid option is ordering a physical laser-engraved metal plate, starting at $59.99. The software itself is open-source and free to use forever.
If you lose your encryption password, there is no way to recover your seed phrase from the encrypted QR code — that's the whole point of strong encryption. Always store your password securely and separately from your QR code backup. Consider using a password manager or writing it down in a secure location.
The best seed phrase storage combines encryption + physical durability. Comparison: (1) Paper plain text — free but burns, fades, and anyone who finds it steals your crypto. (2) Metal plate plain text — fireproof but still readable by anyone who finds it. (3) Encrypted QR code on metal — the winner: fireproof, waterproof, AND encrypted with AES-256 so it's useless without your password even if stolen. SeedVault generates the encrypted QR code for free, and offers laser-engraved stainless steel plates from $59.99.
With SeedVault, you first encrypt your seed phrase and generate a QR code for free. Then you order a laser-engraved metal plate (stainless steel from $59.99 or titanium from $99.99) with your encrypted QR code. The plate is fireproof, waterproof, and indestructible. Crucially, it stores your seed phrase in encrypted form — unlike traditional metal plates that store words in plain text, a SeedVault metal plate is safe even if someone finds it.
Yes — if the QR code is encrypted. A plain QR code containing your seed phrase words would be just as dangerous as writing them in plain text. SeedVault encrypts the seed phrase with AES-256-GCM before encoding it into a QR code, so the QR code alone reveals nothing. Without the correct password, it is just random encrypted data.
To store your seed phrase safely: always encrypt before storing. Never keep plain-text words in a photo, notes app, email, or cloud storage — if your device is ever compromised, your crypto is gone. The safe approach: encrypt with AES-256 (SeedVault does this in your browser, offline), generate an encrypted QR code, then store it anywhere — printed paper in a safe, laser-engraved metal plate, USB drive, or even cloud storage. Without your password, the encrypted QR is completely useless to anyone who finds it.
A mnemonic phrase (also called seed phrase, recovery phrase, or secret phrase) is the 12 or 24 words generated by your crypto wallet when you set it up. It is the master key to all your funds — losing it means losing your crypto permanently. To back up your mnemonic phrase: use SeedVault to encrypt it with AES-256, generate an encrypted QR code in your browser (nothing is sent to any server), then store the QR code in multiple secure locations.
To recover a crypto wallet: open any compatible BIP39 wallet app, choose "Restore wallet" or "Import wallet", then enter your 12 or 24 mnemonic words in the correct order. If your seed phrase backup is a SeedVault encrypted QR code, scan or upload it, enter your password to decrypt, then copy the words into your wallet app.
Never store a plain-text recovery phrase in the cloud. However, an encrypted backup is safe to store online. SeedVault encrypts your mnemonic with AES-256-GCM before creating the QR code. The resulting file can be safely saved to Google Drive, Dropbox, or emailed to yourself — without your password, it reveals absolutely nothing about your seed phrase.
A plain-text seed phrase — whether on paper, metal, or a screenshot — gives instant access to all your crypto if found by anyone. Encrypting it first means the backup is completely useless without your password. You can then store it anywhere (safe, cloud, USB drive, metal plate) without risking theft. SeedVault uses AES-256-GCM encryption, the same standard used by banks and governments.
Encrypt your seed phrase with SeedVault, then order a laser-engraved stainless steel or titanium plate. The metal withstands fire over 1400°C and is fully waterproof. Unlike plain-text metal plates, your SeedVault backup is also encrypted — so even if someone finds the plate, your crypto stays safe.
Plain metal plates (like Cryptosteel or Billfodl) store your seed words as readable text — anyone who finds the plate can steal your funds. SeedVault encrypts your seed phrase first with AES-256, then engraves the encrypted QR code on metal. The result is fireproof and encrypted: finding the plate without the password reveals nothing.
Yes — SeedVault offers steganography, a technique that hides your encrypted seed phrase inside a normal-looking image file (JPEG or PNG). The image looks completely unchanged to the human eye, but contains your encrypted backup embedded in pixel data. This lets you store backups in plain sight on USB drives, cloud storage, or even email them to yourself.
