LegendPass on iOS and Android — passwords on one tab, your private album on the next.
Generate a strong, one-of-a-kind password for every account, then let LegendPass remember it so you never reuse one again.
The router password, the streaming logins, the scan of the lease. Put them somewhere encrypted instead of a notes app.
Not a promise in a policy document — an architecture that makes the promise hard to break.
Your vault is sealed on the device with AES-256. What syncs is ciphertext we have no key for.
Face and palm templates are generated and stored locally. They are never uploaded, shared, or used to identify you.
We cannot reset your master password, because we never had it. That is the trade we made on purpose.
A native app on both platforms plus a Chrome and Firefox extension that approves each unlock from your phone.
Metrics represent platform goals and growth trajectory.

LegendPass pairs 256-bit zero-knowledge encryption with on-device AI gesture and quadratic biometrics (face, palm, gesture, fingerprint) — a combination no other manager offers. Your secure password storage stays readable only by you, with identity protection built in. Learn how we secure your vault or see 40 detailed Q&As.
Yes. The World Economic Forum links 95% of breaches to human error, and Verizon found 86% of web-application breaches involved stolen or weak credentials. A manager removes password reuse and makes every account long and unique.
Servers can be breached, but a zero-knowledge manager stores only ciphertext it holds no key for — so your vault stays unreadable. That is why the key that unlocks your data must never leave your device.
Not strictly, but on-device biometrics add a second factor that a stolen password alone cannot bypass. They also remove the need to type your master password in public. Our quadratic biometrics goes further with face, palm and AI gesture — see the NIST biometrics overview for background.
The best free plans cover unlimited passwords, autofill, and a built-in authenticator. LegendPass keeps all of that free; premium adds on-device document and media vaults plus dual-verification biometrics.
Use LegendPass to manage multiple account logins effortlessly. Every login gets secure password storage with 256-bit zero-knowledge encryption and on-device AI gesture, so your identity protection stays in your hands — ideal for tech-savvy individuals seeking enhanced security.

A simplified view of how a vault is encrypted and synced without the server ever seeing your key.
# A LegendPass vault unlocks only with a key derived from your master password. # The plaintext key is never transmitted; only ciphertext syncs to the server. key = KDF(master_password, salt, iterations) # slow, salted, one-way vault_ciphertext = AES256_GCM.encrypt(key, all_secrets) send(vault_ciphertext) # server sees ciphertext only
Your master password is turned into an encryption key on your phone or computer using a one-way key-derivation function. That key encrypts your vault locally, and only the resulting ciphertext is synced. Because the server never receives the key — only ciphertext it cannot open — even a full compromise of our servers would not expose your passwords, notes, or documents.
Example — a small team of 12 switched from shared spreadsheets and password reuse to LegendPass. Each member stops reusing the same login across work and personal sites (the exact behavior Verizon links to credential-theft breaches). Because the vault is zero-knowledge and each member unlocks with on-device biometrics, the team removed a shared master-password single point of failure. The migration took under an hour using the one-click import tool, and no passwords were ever sent in a group chat again.
A central vault is a single point of failure — on the other hand — concentrating your secrets in one encrypted, zero-knowledge vault is safer than spreading them across dozens of sites where each breach leaks a different password.
Cloud sync means data leaves your device — on the other hand — only ciphertext travels. Your documents and biometric templates stay local, and the sync key never leaves your device, so the trade-off of convenience costs little privacy.
A new password manager has less history than the big names — on the other hand — that is exactly why every server-side claim is zero-knowledge and every biometric is processed on the device, not entrusted to a larger vendor's cloud.
If you want a free password manager that keeps your vault truly private, protects it with biometrics only you can use, and lets you keep your own master password, LegendPass is a strong choice. The free plan already covers unlimited passwords, autofill, the authenticator, and biometric unlock; Premium adds on-device document and media vaults and dual verification. Start with the free plan — there is no card required and nothing about your vault is visible to us.
