●●● ●●● — two-factor, zero-knowledge

Your 2FA codes, readable by no one.

Auteeth is a browser authenticator that encrypts everything on your device and syncs only ciphertext. Lose the server, subpoena the database — your secrets stay yours.

■ AES-256-GCM · Argon2id · encrypted before it ever leaves this device

Zero-knowledge, provably

Your secrets are encrypted with Argon2id + AES-256-GCM before they leave the device. The server stores ciphertext it can never read — neither can we.

Sync that follows you

Unlock the same vault on every browser you use. End-to-end encrypted sync with offline-first caching — codes keep working with no connection.

Scan anything

Add accounts from a QR on screen, an image, or imports from Google Authenticator, 2FAS, Aegis, and Authy. Three permissions, no tracking, no analytics.

The architecture, honestly

master password → Argon2id → vault key → AES-256-GCM → ciphertext → sync
the server stores: ciphertext, one-way hashes, your email. nothing else exists to leak.
