Privacy-First Identity Infrastructure

Login for Apps.
Privacy for Users.

ConsentKeys lets developers add login to apps without ever collecting personal data. Each user gets a secure alias — apps recognise them without storing sensitive information.

Reduces breach risk, meets privacy regulations, free for your first 1,000 users.

Each app gets a unique alias — your real info never shared

How It Works

Steps to Private Authentication

01

User is verified once

Sign in with a magic link — no password, no form. ConsentKeys confirms they're a real person and their real identity never leaves ConsentKeys.

02

ConsentKeys generates an alias

For each app the user accesses, ConsentKeys creates a unique pseudonymous identifier — a “alias”. Different app, different alias. No PII is stored on the app's side.

03

Apps get the alias, never their real identity

The app receives a signed OIDC token. The ‘sub’ claim is the user's alias, not their email. No PII is stored on the app’s side — nothing to breach, nothing to subpoena.

04

User stays in control

Revoke access to any app at any time from the ConsentKeys dashboard. The alias is invalidated instantly — the app loses access without knowing anything about the user.
