The 2025 password manager won't survive 2030
The threat model changed.
The architecture didn't.
Every mainstream password manager you know was designed in the 2017 threat model. None of them ship the cryptography that 2026 actually requires. The numbers are not subtle. The 2017 threat model. None ship the cryptography 2026 requires.

VuVault is the architecture they have not shipped. Built from primitives standardized in the last 18 months — OPAQUE, ML-KEM, WebAuthn PRF, FROST, AKD.
What VuVault gives you What VuVault ships that they can't claim
Three things, no asterisks. Three sentences, all defensible.
01 / 03
Touch ID is enough.
No master password to memorize. Your fingerprint or Face ID unlocks the
vault directly. The same passkey that proves who you are also unlocks what
you have. No master password. Your fingerprint unlocks the vault directly.

Architecturally untouchable.
Your vault is encrypted on your device. The server only ever sees an
opaque blob. Nobody can read it — not us, not a court order, not a future
quantum computer in 2032. Mathematical, not promised. Encrypted on your device. The server sees only an opaque blob — even in
2032.

Server never sees your password.
Authentication via OPAQUE (RFC 9807, July 2025). The server learns no
information about the password — not plaintext, not a hash, not even
during registration. Mathematically proven against pre-computation attacks
upon server compromise. OPAQUE (RFC 9807). Server learns nothing — no plaintext, no hash, ever.

attackers face 256 unbreakable bits. Vault key = HKDF(PRF ‖ SecretKey). 256 bits, never

Credentials first Login · TOTP · SSH · seeds
Logins, secure notes, identities, SSH keys, crypto seeds — every
kind of secret lives in the same encrypted bucket. One unlock,
one keyring, one place to look. Logins, notes, SSH keys, seeds — one encrypted vault. Seven discriminated
ItemKind variants share the
same hybrid envelope. Field-level masking is enforced before
render — secret strings never appear in the DOM until you tap
reveal. Seven ItemKind variants · one envelope · masked-before-render.02
Reveal only on purpose. 30s reveal TTL · 60s clipboard clear
Passwords stay masked. Tap the eye to read for 30 seconds, then
the field re-hides on its own. Copy and we wipe the clipboard 60
seconds later — no shoulder surfing, no lingering paste
buffers. Reveal for 30s, then auto-hide. Clipboard wipes 60s after copy.
REVEAL_TTL_MS = 30_000 in VaultDetail.svelte; clipboard auto-clears via setTimeout(60_000) regardless of clipboard-read permission. Every reveal is
audit-logged locally. REVEAL_TTL_MS = 30_000 · unconditional 60s clipboard clear.03
Safety you can read. Local health · opaque sync state
The vault calls out weak and reused passwords before anyone
else sees them. The check runs entirely on your device — your
passwords never leave it to be graded. Weak and reused checks run on-device. Nothing leaves.
password-health.ts scores entropy and reuse
in-memory; the server only ever observes (deviceId, sequenceClock, ciphertext). Footer
surfaces ZK state, suite, and build hash — proof, not
policy. In-memory entropy/reuse check · server sees only ciphertext + clock. Inside the vault UI rendered from a real session

Local-only. Tier 2 · 2027 Beyond passwords · the ultimate digital vault PDF, image, and document storage · same crypto stack
Beyond file shares.
Beyond cloud backups. Every byte ciphertext.
No exceptions.
Property deeds, car titles, contracts, medical records — the
documents you actually can't afford to lose or have leaked. Each file is sealed
in your browser with the active vault key before it ever touches
local storage or the sync server. Padding to bucketed sizes lands
with the Tier 2 CRDT sync server. Deeds, titles, contracts, records — sealed in your browser, server
holds opaque ciphertext only. Per-document AES-256-GCM under the active session AES key with a
document-scoped AAD (
vuvault-doc-aad-v1) bound to the
document UUID, device salt, and credential id. Encrypted bytes
persist to a separate Dexie table; sync uploads opaque ciphertext to vaults/<accountId>/documents/<blobId>.bin in
R2. Bucketed padding ships with Tier 2 CRDT sync. Per-doc AES-GCM · document-scoped AAD · opaque ciphertext server-side.Tier 2 Dropbox can read your stuff. We literally can't. Architectural privacy, not policy privacy
Cloud storage providers promise they won't look at your files.
We've shipped something stronger — a system where we
mathematically cannot. Encrypted document storage is wired
through the same M3 ciphertext sync path that powers password
sync. Documents encrypted client-side before upload; the server
holds opaque blobs and subpoenaing the M3 sync storage yields
ciphertext nobody can decrypt — including us. The handlers
live in
src/routes/api/documents/[blobId]/+server.ts and refuse anything but base64-encoded sealed bytes.Tier 3 Sign in place. Verify forever. In-vault signing · transparency log entry
Tier 3 design: sign contracts directly inside the vault. Every
signature timestamped and recorded in the public transparency log
— without revealing what you signed. Targets 2028 alongside the
CONIKS-style key directory. Tier 3 design: Ed25519 signature over document hash, anchored
in an append-only Merkle log via VRF. Document content stays
opaque; only existence provable. Lives in the L08 / L11 spec
(
docs/ARCHITECTURE.md).Tier 4 Time-lock for inheritance. drand timelock encryption
Tier 4 design: encrypt your will or instructions to release on
a future date. Nobody — including you — can decrypt early.
Beats a notary, a safe deposit box, and a custodian combined.
Targets 2029+. Tier 4 design: tlock over BLS12-381 threshold network.
Encrypts to a future drand round; decryption physically
impossible until the threshold network publishes that round.
Not yet in any code path.

How VuVault works The cryptographic stack
Four steps. Nothing else needed. Ten layers. Each defensible.
01
You sign up
Pick a Secret Key. Touch your authenticator. No master password to memorize.
02
Your device generates keys
A 256-bit Secret Key + WebAuthn PRF derive your vault key locally. The server never sees them.
03
Vault encrypts itself
Hybrid X25519 + ML-KEM-1024 envelope encrypts your data before any byte leaves the device.
04
Sync without trust
Encrypted blobs travel through the cloud. The provider holds opaque ciphertext only.

Tier 2 capabilities build on the shipped M3 ciphertext
sync path but still need field-level CRDT sync, sharing, and device
transparency before they are product-ready. Tier 3 capabilities (threshold recovery and stronger metadata operations)
target 2028. Today, cells marked tier-2/tier-3 remain roadmap items.

Don't take our word.
Take our hashes.
Three independent ways to verify what's running on your device matches what we say is running. No incumbent ships any of these.
METHOD 01

Every release builds byte-for-byte identically from public source. The
bundle hash appears in your unlock screen. Compare it to the GitHub
release hash. Bundle hash on every unlock screen. Compare to the GitHub release hash.
