Zero knowledge encryption

We Can’t Read Your Data — And That’s the Point

At PasswordLab, we’ve built our entire encryption model around one promise: we can’t access your data, even if we wanted to. This is true zero knowledge encryption — not just a marketing term, but a technical guarantee that your vaults are only accessible by your team.

We’ve implemented Shamir’s Secret Sharing to ensure every piece of data stored in PasswordLab is protected, distributed, and accessible only with quorum-based trust.

How It Works

PasswordLab never stores the master encryption key that protects your data. Instead, we generate it using a cryptographic algorithm called Shamir’s Secret Sharing, which breaks the master key into 5 independent pieces called shares.

Here’s what makes it secure:

• The master key is never stored. Ever.
  It exists only temporarily in memory.

• 5 shares are generated, 3 are required to reconstruct the key.
  This means no single person or system holds the full key. A quorum of 3 trusted shares is needed to access encrypted data.

• Even if your infrastructure is compromised, attackers gain nothing without the required threshold of shares — and without knowing how they’re distributed.

This approach combines the strength of AES encryption with the resilience of decentralized trust, ensuring that vault access isn’t just encrypted — it’s cryptographically gated by design.

What Zero Knowledge Means for You

• No password ever leaves your environment in plain text
  Not during transit. Not during storage. Not ever.

• Your team holds the keys
  Access control is not only role-based — it’s cryptographically enforced.

• We can’t help attackers even if we’re breached
  There's simply no usable data to extract. Without your shares, vaults stay sealed.

• Peace of mind for IT teams and CISOs
  No blind trust in vendors. No backdoors. Just strong, math-based security you can audit and verify.

Built for Businesses Who Take Privacy Seriously

If your business handles sensitive client information, intellectual property, or internal credentials, zero knowledge encryption isn’t a nice-to-have — it’s a must.

PasswordLab gives you:

• A provable zero knowledge architecture
• A distributed key model that resists insider and outsider threats
• Full compliance alignment for data protection regulations

Trust Shouldn't Be Assumed. It Should Be Engineered.

With PasswordLab, you never have to wonder who has access to your data — because the answer is simple: only you.

No one else. Not even us.
