Secure by design — your secrets never leave this PC

One authenticator for everything.
Nothing leaves your PC.

SentinelAuth keeps all your two-factor codes — Microsoft, Google, Adobe, and any service that uses standard TOTP — in a single, locally-encrypted vault on your Windows machine. No accounts. No cloud. No telemetry.

  • 🔒 AES-256 + Argon2id
  • 🚫 No accounts
  • 📡 No servers
  • 🔕 No telemetry

Everything your authenticator should be

Built for people who are tired of juggling a dozen authenticator apps — and tired of trusting them with the cloud.

🛡️

A vault that stays put

Your secrets are encrypted at rest with AES-256-GCM and a key derived by Argon2id from your master password. The vault never leaves your device.

🔑

Works with everything

Any service using the open TOTP standard — Microsoft, Google, Adobe, Amazon, GitHub and thousands more. One app replaces them all.

🎨

Real brand logos

Browse an online catalog of ~2,800 brand icons and give every account its proper logo — or use your own image. Icons load on demand; nothing about your accounts is ever sent.

🌗

Light, Dark & System

A polished interface that matches your Windows theme automatically, with per-card fonts, sizes and colors when you want to make it yours.

👤

Windows Hello unlock

Unlock with your face, fingerprint or PIN. Auto-locks when idle or when Windows locks, and keeps copied codes out of clipboard history.

📷

Import in seconds

Scan a QR from the screen or an image, paste otpauth links, or import a Google Authenticator export — then review and tidy each account before it's saved.

💾

Backups you control

Encrypted vault backups and QR-code export live on your terms — move to a new PC or keep an offline copy without handing anything to a third party.

📌

Pin & organize

Drag to reorder, pin the accounts you use most to the top, and search instantly. The codes you need are always one glance away.

Privacy isn't a setting — it's the architecture

The only thing that leaves your machine is nothing.

Most authenticators sync your secrets to someone else's cloud. SentinelAuth doesn't have a cloud. There's no account to create, no server to trust, and no analytics phoning home.

  • Secrets encrypted locally with AES-256-GCM
  • Master password stretched with Argon2id — never stored
  • The one optional network feature (brand icons) is opt-in and sends nothing about you
  • Open TOTP format — you're never locked in

If it uses TOTP, it works here

Set up "a different authenticator app" on any service and scan the code. These are just a few of the thousands that work:

Microsoft Google Adobe Amazon GitHub Dropbox Facebook Discord PayPal Cloudflare

One app, yours to keep. (Final pricing is being set up — this is a placeholder.)
