Biometric Approval
Use the biometric security already available on a customer’s phone, such as Face ID or Touch ID, to approve an action.

Transaction Authentication
AuthKey MFA
Prove every high-risk approval, not only the login.
AuthKey is a transaction-authorisation layer that uses device-based biometric verification to approve payments and other high-risk actions without passwords or one-time codes.
The business challenge
Why organisations consider this solution.
A successful login does not prove that a customer intended a specific payment or high-risk action. Organisations need strong approval that remains clear and easy for the user.
Core capabilities
What AuthKey MFA
helps you do.
Transaction Binding
Cryptographically bind the approval to the specific transaction details, including the intended amount and recipient.
Passwordless Experience
Remove passwords, codes and unnecessary app switching from the approval journey while retaining high assurance.
High-Risk Action Control
Apply stronger verification to sensitive payments, privileged actions and other decisions that require clear user intent.
Reference architecture
See the actual
solution topology.
Bind the exact transaction to a registered device, verify the approver biometrically and return cryptographic proof of intent. The diagram below shows the product's distinct operating model, data paths and enforcement or decision points.
Illustrative reference architecture — final design depends on the customer environment and vendor-supported integration pattern.
Example use cases
Apply the architecture
to a real scenario.
These examples explain the business purpose behind the architecture. Final scope, integrations and outcomes depend on your environment and implementation design.
01Retail payments
Approve a new beneficiary payment
A bank wants stronger assurance when a customer pays a recipient for the first time.
- 1Send the exact payment details to the device
- 2Confirm with Face ID or fingerprint
- 3Sign and return the approval proof
Expected resultThe approval is tied to the amount and recipient, reducing OTP-style fraud.
02Corporate treasury
Authorise a high-value disbursement
A large supplier payment requires executive sign-off and a traceable approval trail.
- 1Trigger policy-based step-up
- 2Verify the authorised executive
- 3Store the signed transaction evidence
Expected resultFaster high-trust approval with clear audit evidence.
03Sensitive operations
Protect a privileged action
An administrator attempts a high-risk configuration or financial action.
- 1Present the action details for review
- 2Require device-bound biometric confirmation
- 3Execute only after signature validation
Expected resultA stolen password alone cannot approve the protected action.
Delivery path
From requirement
to production value.
The exact architecture depends on your environment, but the solution typically follows this practical operating flow.
Initiate the action
The banking, payment or enterprise system sends the exact approval context to AuthKey.
Present clear details
The user sees what is being approved, including the relevant transaction or high-risk action information.
Verify on the device
The user confirms with the phone’s supported biometric security instead of typing a password or OTP.
Validate the approval
The system verifies that the authenticated approval is bound to the intended action before proceeding.
Typical use cases
Where it fits.
- Payment and beneficiary approval
- High-risk banking transactions
- Privileged-access confirmation
- Sensitive enterprise workflow approval
Expected outcomes
What success looks like.
- Stronger proof of user intent
- Lower exposure to stolen passwords and intercepted codes
- Less friction during secure approval
- Clearer control over high-risk actions
