One authentication platform, four ways to put it to work
Every product below runs on the same appliance and the same phone app — start with the access problem that hurts most, add the rest when you’re ready.
N-VPN
2-factor authentication for VPN
Add a phone-tap second factor to any VPN without replacing your firewall, your RADIUS setup, or your users’ habits.
For IT teams running any RADIUS-compatible VPN (Cisco, Fortinet, MikroTik or anything in between) who need a second factor without a forklift upgrade.

Passwordless single sign-on
Eliminate passwords across your web applications, and the reset tickets, lockouts and phishing exposure that come with them.
For organizations whose helpdesk queue is full of password resets, and whose web applications already speak SAML or OAuth.
Learn more →N-WINKEY
Passwordless Windows login
Secure Windows workstations, terminal servers and remote desktops with the phone your employees already carry.
For fleets of Windows workstations, terminal servers and internet-facing RDP endpoints that attackers probe every day.

Transaction signing
Let customers approve payments and sign documents with a cryptographic seal that stands up to auditors and regulators.
For banks, fintechs and services that must prove PSD2 dynamic linking, or need legally binding document signatures.

Integrate it your way
Use the Notakey Authenticator app as-is, brand a white-label version, or embed authentication into your existing app. Services can share one cryptographic key pair or keep separate ones — your call. Everything runs over a documented REST API.
