Verify the identity of customers anywhere in the world in transactional flows and ensure a secure process. A set of capabilities in a single journey, tailored to the scenario you need.

### What these products solve

Step-up authentication flows address a core business need: re-authenticating the user with minimum friction during sensitive operations, without compromising security. They act after sign-up — that is, when the user is already registered and needs to be confirmed as the legitimate holder in moments such as:

- Transfers
- Password or limit changes
- Service subscriptions
- New device registration
- Financial operations (investments, loans, cashout), among others.

### Choose the scenario for your integration

Our products are pre-configured combinations of capabilities designed for specific scenarios. Select the one that best fits your business challenge:

  **Smart revalidation**
