Login procedures

One component of our multi-level security system is the login procedures that we offer to users of our e-services. This gives you access to your finances and stock exchange transactions any time and anywhere.

You need your e-finance number and password for all login procedures. For customers with several users, user ID is required.

Regardless of which form of login you choose: all login procedures use several factors for authentication and meet the highest security requirements. Data transfer between your device and PostFinance is also encrypted at all times.
