Passwordless Login, Backed by Real-Person Liveness
FacePlugin delivers self-hosted biometric authentication that confirms both who a user is and that a live person is standing in front of the camera. Swap out static passwords and one-time codes, layer a face-and-liveness check onto multi-factor authentication, or gate sensitive actions behind a fast identity check – all while keeping biometric processing inside your own servers, private cloud, or supported mobile hardware. Because everything runs on infrastructure you control, there’s no per-authentication processing fee to budget around.
What Biometric Authentication Actually Verifies
Biometric authentication confirms that the person requesting access is the same individual who originally enrolled, by comparing a fresh biometric sample against a previously stored template. FacePlugin builds this around facial biometrics: a user presents their face, the system checks that a live human is actually present, and the resulting capture is scored against the enrolled template.
This is a different job from identity verification, which typically establishes who someone is the first time they onboard. Authentication instead answers a narrower question – is this returning user the same person as before? – and FacePlugin can slot that answer into several access models:
- Passwordless sign-in: Replace a typed password or texted code with a verified face.
- Multi-factor authentication: Pair face verification with a password, trusted device, security key, or other factor.
- Step-up checks: Trigger an extra face-and-liveness scan before a sensitive or high-value action.
- Account recovery: Confirm the enrolled user’s identity before a password reset or account-access request is approved.
Each check returns a structured match-and-liveness result to your application rather than a black-box yes/no. Your app, IAM, or SSO platform stays in charge of the actual decision – authorizing, rejecting, or escalating the request according to your own access policy.
Matching Faces Isn’t Enough – You Need Liveness Too
Face matching by itself can tell you whether two templates look alike, but similarity alone doesn’t prove a real person is actually there. Liveness detection closes that gap by adding presentation-attack detection to the authentication step. FacePlugin pairs face matching with passive or active liveness checks so common spoofing attempts get identified and blocked, including:
One SDK Call, a Complete Identity Decision
FacePlugin’s biometric authentication bundles face detection, template extraction, and active or passive liveness into one lightweight SDK.
Liveness-backed matching
NIST-evaluated face recognition combined with presentation-attack detection stops photos, videos, and masks.
On-premises deployment
Biometric templates and match decisions stay inside your own infrastructure and are never routed through a third-party cloud.
On-device ready
Authenticate on mobile hardware even while offline – nothing about the check needs to reach the network.
IAM friendly
Wire the SDK’s decision into your existing identity, SSO, or workforce-access stack through a small set of straightforward APIs.
Sub-second authentication
Get an auditable match / no-match verdict back in under a second, so sign-in still feels instant.
Practical Places to Put Passwordless Face Login
Workforce SSO
Swap VPN, desktop, and SaaS passwords for a quick face check at sign-in.
Customer account access
Let end users open mobile and web apps with their face instead of typing a password or waiting on an OTP.
Step-up authentication
Require a liveness-backed face check before high-risk actions such as transfers, password resets, or privilege escalation.
From Enrollment to Access in Three Steps
Enroll
The user registers a face template a single time; it’s generated and stored entirely inside your own environment.
Authenticate
At each login the SDK captures a selfie, checks for liveness, and compares it against the stored template.
Authorize
A pass / fail decision comes back for your app or IAM platform to act on – granting access or triggering a step-up check.
Frequently Asked Questions
How does FacePlugin verify who a user is?
FacePlugin authenticates users by pairing facial biometrics with liveness detection, giving you a secure alternative to passwords or an added layer on top of them.
Can FacePlugin stop spoofing attempts?
Yes. Built-in liveness detection recognizes and blocks spoofing attempts that use printed photos, replayed videos, digital screens, or 3D masks before an authentication request is ever approved.
How are biometric templates kept safe?
Rather than storing raw face images, FacePlugin generates encrypted biometric templates that stay securely on your own servers or private cloud – never in a third-party database.
Will FacePlugin plug into our existing identity systems?
Yes. The SDK integrates cleanly with existing IAM, SSO, and authentication platforms by handing back straightforward face-match and liveness results your systems can act on.
Does authentication work on both mobile and web?
Yes. Face authentication runs through standard web cameras as well as native iOS and Android SDKs, including fully on-device operation for offline or high-privacy deployments.
