1Kosmos BlockID is a passwordless identity-proofing platform: it verifies a real person with documents and biometrics, then authenticates them without a password. It belongs on flows where knowing who the user actually is matters more than convenience.
Copy the redirect URI
In the Authdog console, select the project and environment, open Authentication > Providers, find 1Kosmos BlockID, and click Enable. Copy the redirect URI shown in the form:
https://identity.authdog.com/api/v1/callback/<connectionId>Create the application
- Create an OIDC application in your 1Kosmos BlockID tenant.
- Add the redirect URI from Authdog to the application's redirect URIs.
- Copy the issued Client ID and Client Secret.
- Note your tenant host — that is the Domain URI.
Configure Authdog
| Field | Value |
|---|---|
| Client ID | The client identifier from the provider |
| Client Secret | The client secret from the provider |
| Domain URI | Your 1Kosmos tenant host |
Save, then toggle the connection active.
What 1Kosmos BlockID returns
Authdog requests the openid profile email scopes and reads the profile from https://<domain>/userinfo.
The tenant's userinfo endpoint returns the standard OpenID Connect claims for the verified identity.
Proofing happens in BlockID, before Authdog sees the user. Treat the resulting session as high assurance only if the tenant's proofing policy actually requires it.
Test it
- Open your environment's hosted sign-in page, or link to
https://identity.authdog.com/api/v1/signin/<connectionId>. - Select the 1Kosmos BlockID button and complete the flow.
- Confirm the user appears under Users in the console with a 1Kosmos BlockID identity linked.
Troubleshooting
| Symptom | Cause |
|---|---|
invalid_client |
The application belongs to a different tenant than the Domain URI |
| Redirect or callback URL error | The URI registered with the provider does not match Authdog's exactly |
| Works in one environment only | Each environment has its own connectionId, and so its own redirect URI to register |
