Decentralize Your Password Security

Experience true password ownership across all devices with blockchain-powered self-custody.

Web3 native

Connect your wallet and access your passwords on any device. That simple.

Permissionless

Experience unmatched privacy with blockchain-backed, gatekeeper-free security.

Self-custody

Your wallet holds your passwords. No secrets leave your devices. No trust required.

Hassle-free

Embrace anonymity: no accounts, no credit cards — just pure privacy.


Built for Web3

Just connect your wallet.

You won't need to create an account, or give your credit card, or write down yet another master key. Neulock is private, decentralized, trustless, and permissionless.

If you're a Web3 degen like ourselves, Neulock is the dapp you've been waiting for. Your wallet has full custody of your passwords, and you can access them on any device where your wallet is connected.

Blockchain for passwords, really?

Think placing passwords on the blockchain is risky? You're right. Neulock ensures your passwords remain protected even if your on-chain data gets decrypted and published.

Traditional managers rely on vulnerable servers and breakable encryption. Neulock transcends these weaknesses by securely backing up and syncing your passwords without ever exporting secrets, not even under encryption.

Security comparison

Neulock builds on the security model of the original Neulock Cloud Password Manager, and adds the following benefits:

Here's how Neulock compares to your typical cloud password manager:

RiskNeulockCloud Password Managers
End-User Device CompromiseAt Risk All password managers are vulnerable if device security is compromisedAt Risk Idem
Server BreachSafe No Neulock-generated passwords are stored neither on servers, nor on-chainAt Risk Passwords potentially compromised, depends on encryption effectiveness and master key strength
Subscription lock-outSafe No subscription; your passwords are always available by connecting your walletAt Risk You may be locked out due to credit card issues
Password manager company going out-of-businessSafe All data backed by 3+ FileCoin permanent IPFS storage contracts, indexed on-chain; full data self-custody possibleAt Risk Your data may be unretrievable if their cloud infrastructure goes offline
Master key bruteforce attackSafe 256-bit master key derived from wallet is impossible to bruteforceAt Risk Humans can create weak master keys
Encryption Algorithm ObsolescenceSafe Passwords not stored, thus not affectedAt Risk Stored passwords may become vulnerable
Master Key Recovery Mechanism ExploitedSafe Master key derived from wallet onlyAt Risk Recovery mechanisms can be a weak point
Quantum Computing AdvancesSafe Utilizes quantum-resistant algorithmsAt Risk May not be equipped with quantum-resistant measures
