Nothing to sign into.

Nothing to send us.

Nothing between you and your codes.

Security without the ceremony.

Open the app, read your code, and get on with your day. The important work happens quietly underneath.

LOCAL / 01

Works without a signal

Codes are generated directly on your device. Airplane mode, patchy Wi-Fi, or no service at all—it still works.

PRIVATE / 02

Encrypted at rest

Your authenticator secrets are protected on device and never sent to a custom backend.

FAST / 03

One glance, one tap

Clear codes, a visible countdown, search, categories, and copy make everyday sign-ins effortless.

YOURS / 04

Core access stays free

Reading and copying the codes you own will never be placed behind a subscription.

From QR code to six digits. No detour.

Scan a setup code or enter a key manually. Authenticator validates it, encrypts it, and starts generating codes on your device.
