Back up your BIP39 recovery phrase
Your BIP39 recovery phrase is the master key to everything it protects — and a sticky note is no way to keep it. KeysArk stores it end-to-end encrypted, derived from a phrase only you hold, synced to your own cloud.
KeysArk speaks the standard: new vaults use a 24-word BIP39 phrase (256 bits of entropy) that you can import into MetaMask or any BIP39 wallet. Nothing proprietary to lock you in.
Why a vault beats paper or a screenshot
- Encrypted with AES-256-GCM in your browser — a screenshot in your photos is plaintext.
- Synced to your own Google Drive or Baidu netdisk, not a company database.
- Exports carry a provenance manifest so you can still decrypt them years later.
- Open source, so you can verify the phrase never reaches any server.
FAQ
Is it safe to store a recovery phrase online?
Only if it is encrypted before it leaves your device. KeysArk encrypts in your browser with a key derived from a phrase only you hold — the server stores ciphertext it cannot read.
Does KeysArk use standard BIP39?
Yes. New vaults generate a standard 24-word BIP39 phrase, importable into MetaMask or any BIP39-compatible wallet.
Can I still decrypt my backup years from now?
Yes. Every export embeds a provenance manifest recording the exact software and crypto spec that made it, so a future you can reproduce the environment and decrypt.
Is it free?
Yes — KeysArk is free and open source, with your encrypted backup stored in your own cloud drive.
