How does it work?

The Nexus service provides an easy way to enforce two-factor authentication by customers and citizens to access your web services, using Swedish BankID.

Nexus acts as the so-called relying party for BankID, which means that Nexus handles all costs and contracts towards the BankID-selling bank.

For a smooth implementation, complete instructions are available online.
