Migration of the authentication service for 2.5M users

Digital Product Manager, Viseca

Situation

The authentication platform was end of life and no longer supported.

Action

Ran the RFP, supplier selection and contract; planned features in SAFe across several PIs and delivered them as PO and PM with the dev teams.

Result

All 2.5M users migrated, with zero downtime and zero user loss.

Step 1: the one app's welcome screen with Login and Register
Step 2: the Face ID prompt during login
Step 3: the Cockpit with spending, available amount and recent transactions

Original screens in English, iOS 27

Zero downtime
  1. Step 1

    You tap Login. The app looks exactly as before.

  2. Step 2

    In the background your account moves to the new platform. It takes a few seconds longer than usual, that is all you notice.

  3. Step 3

    You land in the Cockpit. Nothing has changed for you; you are already signed in on the new platform.
