Frequently Asked Questions
Use SeedVault to encrypt your seed phrase with AES-256 encryption, then generate an encrypted QR code. You can print it, engrave it on a fireproof metal plate, or store it digitally. Without your password, the QR code is completely useless. Always use strong passwords and store backups in multiple secure locations.
Yes. SeedVault is 100% client-side β 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 hides your encrypted seed phrase inside a normal-looking image. The image appears completely unchanged, but contains your encrypted data hidden in the pixel values. It's perfect for storing backups on USB drives, cloud storage, or emailing to yourself without anyone knowing it contains sensitive data.
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 β 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 β 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 backup combines encryption with physical durability. Encrypting your seed phrase with AES-256 before storing it means even if your backup is found, it's useless without your password. SeedVault lets you generate an encrypted QR code for free, which you can then engrave on a fireproof stainless steel or titanium plate β the most secure backup method available for a crypto recovery phrase.
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 β unlike traditional metal plates that store words in plain text, a SeedVault metal plate is safe even if someone finds it.
Yes β 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.
How to Backup Your Seed Phrase Securely
Your seed phrase (also called a recovery phrase or mnemonic) is a sequence of 12 or 24 words that gives full access to your crypto wallet. Losing it means losing your funds β forever. Backing it up securely is the most important step in self-custody.
Why plain paper or metal is not enough
Writing your seed phrase in plain text on paper or engraving it directly on metal leaves it fully readable to anyone who finds it. A fire-resistant metal plate protects against physical damage, but not against theft. The best seed phrase backup combines physical durability with encryption.
The SeedVault method β encrypt first, then store anywhere
SeedVault encrypts your seed phrase with AES-256-GCM (the same standard used by banks and governments) and converts it into a QR code. The encrypted QR code is completely useless without your password β even if someone finds it. You can then:
Print it on paper and store in a safe
Get it laser-engraved on stainless steel or titanium β fireproof, waterproof, indestructible
Store it digitally (cloud, USB, email) β safely, since it's encrypted
Hide it inside an image using steganography
Best practices for crypto seed phrase backup
Never store your plain-text seed phrase digitally (no photos, no cloud, no email)
Use a strong, unique password for encryption β store it separately
Keep multiple copies in different physical locations
Test your backup by decrypting it before relying on it
For maximum security, use SeedVault offline on an air-gapped device
