​Step 2:

The end user is directed to the bank's identification client. See each individual bank's look and feel when testing the service. When directing the user to the bank's client, the identification is redirected entirely to the bank's identification page. 

End user routed directly to the bank's client

​You may also design your own bank selection page and skip the page in step 1 above. If designing your own bank selection page, set the amr_values parameter to fi_tupas and the forcebank parameter to the user-selected bank. The different forcebank parameters can be found on the OIDC page.
