# What if a User forgets their PIN or wants to change association method?

## Authorized resets or switches preserve baseline and history; PIN updates require synchronization.

**Forgotten PIN.** An Administrator or Agent clears the PIN in the dashboard. They do not set or see a new PIN. After the Device synchronizes, the User sets a new PIN on the Device at the next assessment. Until the Device synchronizes, the previous PIN remains valid on it.

**Changing the PIN.** A User who remembers the current PIN changes it on the Device. The change reaches other Devices when they synchronize.

**Changing association method.** The User requests the switch through the route the Customer has defined. An Administrator or Agent enables it, and the User makes the new choice on the Device. On a switch from iris recognition to PIN, the Service automatically deletes that User's Iris Identification Data from active systems.

None of these actions affects the User's baseline, measurement history, or results.
