Enable BankID in your services
To get you started with BankID identification through E-Ident, Nets will need a merchant certificate and some configuration setting information from you. The configuration settings are supplied in the setup dialogue with support.
More information about BankID:
Merchant certificate
Nets through the Signing and Identification Services are resellers of BankID merchant certificates, and this can be ordered either separately or together with E-Ident and/or E-Signing. When ordering a merchant certificate through Nets, you will receive an information letter asking you to complete a form with information needed to create a BankID “brukerstedsavtale” with BankID Norge. Note: In this form you need to specify if you are allowed to handle SSN.
The form shall be returned to our support and based on the form Nets will register this order at BankID. After the registration you will be asked to confirm and sign the order. When the order is signed with BankID Norge, it will be sent to your bank for processing. Your bank may use up to 10 business days for processing the order. Nets will then receive activation information for your BankID merchant certificate from your bank. The merchant certificate will be activated and connected to your configuration.
In cases where you use another reseller, the BankID activation link and code must be sent to Nets without activating it. Contact Nets support to get contact details of receiver of the link and code.
Test merchant certificate
Nets will set you up with a common test merchant certificate if nothing else have been agreed.

Possible ACR values
Merchants set up with the new (purple) BankID style and user experience will have access to control the level of assurance for a specific identification. The actual used level of assurance will be returned in the acr claim/attribute. If the acr_values parameter is not defined, the level of assurance will default to "urn:bankid:bid" = high. Supported values for the acr_values identification parameter are:
- urn:bankid:bid
- urn:bankid:bis
Possible values for acr claim/attribute are:
- urn:bankid:bid;LOA=4
-
urn:bankid:bis;LOA=3
Handling of SSN
All companies that are allowed to handle social security numbers (SSN) can get this in return after a BankID identification. For customers using the SAML protocol, SSN is returned as default, but this can be turned off by appending returnssn=false to the identification request. For customers using OIDC, SSN will only be returned if scope=ssn is set in the identification request. Read more about the optional eID specific scopes and identification request parameters for OIDC and SAML respectively.
Note: Remember to specify that you want to process SSN when ordering your BankID merchant certificate and giving Nets your E-Ident configuration details.
BankID Biometric
BankID support biometrics based authentication, where end users can use facial recognition and/or fingerprints in the BankID app to log-in and access services online. By doing so, users will experience that the login process will go from 30 seconds to just a few seconds. The level of assurance for BankID Biometrics is defined as "substantial" where as regular BankID (two-factor based) authentication is considered as "high".
If you want to allow end users to authenticate using BankID Biometric, you need to be set up on the latest (purple) BankID style and you will need to set the acr_values to "urn:bankid:bis", as described in the section above. Please reach out to us if you still don't have access to the new BankID style with biometrics support, and we will assist you in the migration process.
User experience
The below three images shows the flow for a standard BankID authentication. On the left side, the old "Legacy BankID" flow is shown, and on the right side, the latest BankID flow is shown. Step 2 may differ depending on the authentication methods available for the user.

BankID in IFRAME
BankID doesn't support iframe, with one exception. If your implementation is using the old Legacy BankID, you may still run the BankID client in an iframe, and the recommended and minimum IFRAME sizes from BankID are:
- Large screen (Desktop/tablet): 396px (w) by 280px (h) (recommended) / 370px (w) by 204px (h) (minimum)
- Small screen (Smartphone) (only minimum sizes): 320px (w) by 350px (h) (portrait) / 480px (w) by 200px (h) (landscape)
CSS file adjustment for Legacy BankID in iframe
The BankID client may be styled with CSS. The default styling has CSS rule that set the proper sizes. Styling can be overridden either by setting av style URL in the customer configuration at Nets or by sending a style parameter when starting the identification. The default CSS styling sets width and height to 100%. The client will then expand to fill the container (iframe), regardless of the container size.
When overriding styling, the sample CSS below will produce the same effect as the default styling.
#nobankid_index_html {
height: 100%;
overflow-y: hidden; /* make sure no scroll bar is shown */
}
#nobankid_index_html .iframe,
#nobankid_index_html .iframe .ipage {
height: 100%;
}
#nobankid_index_html .iframe .ipage .main {
height: 100%;
min-height: 200px;
}
