Your passwords, encrypted before they leave your device.
PassCrypt is the zero-knowledge password manager built so that even we can't read your vault. Your master password never leaves your browser - so even if our servers are breached, your data is unreadable noise.
AES-256-GCM encryption · Argon2id key derivation · $0 free forever · PayPal accepted worldwide · Trusted since 2025
Your passwords are already at risk.
Traditional password managers store your decryption keys on their servers. That means one successful attack on them exposes every password you own.
The MOAB (Mother of All Breaches) in early 2025 alone leaked 26 billion records. 2026 continued the trend - every major breach traced back to a centralised credential database holding server-side decryption keys.
The Verizon 2025 DBIR confirmed credentials remain the #1 attack vector. Legacy managers encrypt your vault but hold the decryption keys server-side - trusting their security posture with your entire digital life.
A 2025 Google/Harris Poll found 65% of people reuse the same password across multiple accounts. One breach cascades into a complete digital identity takeover.
PassCrypt was built on one absolute rule:
"No server ever holds a key that can decrypt your data - not ours, not anyone's."

Military-Grade Frameworks
Every layer is designed around the core invariant: your cryptographic credentials never leave your hardware. Explore full features & specs
Zero-Knowledge Security
Your Master Password never transmits. Argon2id derives the wrapping key inside browser memory. We store encrypted ciphertext only.
Native WebCrypto Sandbox
All operations execute inside your browser's native, compiled WebCrypto runtime. Zero dependence on third-party security npm packages.
Real-time Syncing
Instant encrypted replication across all registered devices. Updates sync as base64 encryptions over zero-knowledge transport lines.
Sovereign Portability
Export all records decrypted entirely inside your sandboxed web memory into JSON or CSV. Zero vendor lock-in. Ever.
Wipe-On-Lock Invariant
Vault automatically locks and deletes data encryption keys from SessionStorage on idle timeout, tab close, or window blur.
Federated Teams & Family
Deploy isolated group environments. Manage credentials without the administrator ever holding the keys to access vaults.
Quick Access PIN (QAP)
Set a 3–6 digit PIN required each time you reveal a password. Every reveal, every time - no session caching. Reset via master password + email OTP with a 3/day safety limit.
Argon2id Key Hardening
Derive keys using hardware-resistant parameters (m=64MB, t=3, p=4) optimized to block GPU brute force, throttling attackers to 2–4 guesses/second.
Zero-Trust Compliance Audit
Architecturally compliant with GDPR, CCPA, and India's DPDP Act 2023. Logging database activities using append-only, immutable audit trails.
Three Steps to Isolation
How your records transition from plaintext to military ciphers in under two minutes.
Register Identity Sandbox
Select your master password locally. The system instantly generates a unique 16-byte cryptographic salt on database registry.
Derive Keys On-Hardware
Your CPU processes the inputs using Argon2id. Master Key wraps the vault DEK. Auth Key hashes prove your identity.
Synchronize Sovereign Cipher
Your browser decrypts records instantly as they load. We store and sync encrypted blobs - meaning absolute zero tracking.
Verifiably Secure.
We employ strict industry-standard implementations verified by independent audit patterns. We prioritize cryptographic invariants over browser convenience. Audit cryptographic specs & sandbox layers
Not all password managers are equal
Most alternatives encrypt your vault but hold the keys. That's the difference between a locked box and a box where someone else has a copy of your key.

What security-minded people say
From individual developers to enterprise security teams - built for anyone who refuses to compromise on digital privacy.
“When the MOAB leak hit in 2025 I had accounts in there. Spent a month rotating credentials. Switched to PassCrypt immediately - zero-knowledge means even if they get breached tomorrow, my vault is unreadable noise. Should have done this years ago.”
“We store RBI-regulated payment gateway keys, AWS root credentials, and client API tokens here. After the 2025 wave of SaaS supply-chain attacks, I needed a manager where a server compromise yields zero. PassCrypt's Argon2id derivation on-device is exactly that guarantee.”
“I reviewed the full crypto architecture before recommending it to my CERT team. AES-256-GCM with per-entry random nonces, Argon2id at 64MB memory - this is textbook correct. The interactive KDF playground publicly demonstrates their implementation. Rare transparency.”
“Finally - transparent pricing with no conversion nonsense. My 12-person product team all switched in one sprint. The Quick Access PIN feature is brilliant for daily use - one tap PIN to reveal, full zero-knowledge underneath.”
“The Federated plan for my family is exactly what I wanted. My wife and parents each have completely isolated encrypted vaults - I pay the bill but can never read their passwords. No other manager offers this model at this price point, anywhere.”
“The one-click local JSON export sealed it for me. After watching two major password managers get acquired and shut down in 2025, vendor lock-in is a real risk. With PassCrypt my data is mine - decrypted in-browser, no server round-trip, fully portable.”
