1:1 Validation
When the user has already gone through onboarding, 1:1 Validation confirms that whoever is in front of the camera in this transaction is the same person from the initial registration.
What it does
Compares the selfie captured in the current session against the selfie captured in a previous process — referenced by that process's identifier. Returns a binary verdict (same person or not), with no probabilistic score.
Inputs
- A capture session opened via Create Process with a flow that includes 1:1 Validation.
- Reference process identifier (the original registration / onboarding to which this validation will be compared).
Possible responses
| Response | Meaning |
|---|---|
YES | The face is the same as in the reference process. |
NO | The face is not the same as in the reference process. |
Availability
| Integration components required |
|---|
| API Web or SDK |
Valid combinations
1:1 Validation appears in flows that include the token suffix:
idtoken, idtokentrust, idtokensign.

1:1 Validation vs Smart Revalidation
Both 1:1 Validation and Smart Revalidation address the question "is this the same person from the registration?". The difference:
- 1:1 Validation always requires a new active selfie to compare with the reference.
- Smart Revalidation orchestrates multiple authentication tiers (metadata, silent authentication, facial biometric) adaptively, choosing the least-friction approach for each transaction based on real-time risk signals.
