Silent Authentication Node

Silent Authentication is non visual node and it checks if a user is already signed in through their bank or national ID service (in Finland, Denmark, Sweden, or Norway). When a user is already authenticated via a supported provider before entering TellUs, this node allows them to proceed without requiring additional authentication steps.

Use Case

Use the Silent Authentication node when you want to:

• Allow users who are already authenticated via a supported bank or national ID service (in Finland, Denmark, Sweden, or Norway) to proceed without additional authentication steps.
• Improve user experience by reducing friction during the authentication process.
• Seamlessly integrate with existing authentication systems to verify user identity.

Don't use it when:

• Your application does not support users from Finland, Denmark, Sweden, or Norway.
• You require explicit user authentication for security or compliance reasons.

UI Examples

TellUs

Only output, no UI

WebChat

Only output, no UI

Behavior

• Blocking: the node waits for the user to be authenticated
• Produces output: creates multiple output properties based on user account details
• Supports validation: can be marked as required/optional
• Moves to the next node after authentication is confirmed
