We advise Free Software apps such as FreeOTP (download links below), but you are free to choose any apps that implement the open OTP standards.
Other mobile apps known to work with our system are google authenticator and andOTP. However, any app implementing the open TOTP standard will do.
|Leiden University suggests the use of the NetIQ Advanced Authentication App for 2FA. Should you want to install this proprietary software, you should know that the QR codes generated by this app differ from those generated by Free TOTP apps and can lead to 2FA problems if you scan a NetIQ-generated QR code with a Free app.|
Navigate to any of the Lorentz Institute SSO web applications, for instance our Remote Workspace.
You will be redirected automatically to the Lorentz Institute Identity Provider login page as in Figure 1.
Enter your IL credentials to sign in. Upon successful login, you will be redirected to a page containing a QR code to be scanned via your OTP mobile app (Figure 2). The QR code contains your shared secret key and other useful information regarding the OTP algorithm used by the IL authentication infrastructure.
Open your OTP app and scan the QR code. Your secret key will now be stored on your phone and a new entry called Lorentz Institute Intranet with its corresponding TOTP will be created in your app (Figure 3). Insert this TOTP in the One-time code form input and, if you wish, a label in the form input called Device Name. This label is meant to help you keep track with which device the secret key has been shared. Click on Submit.
If Step 3 succeeds (errors might occur if there is too much lag time, i.e. the OTP expired), the system will send you an email to your private (not @lorentz) e-mail address with precise instructions on how to verify your identity. If your identity cannot be validated, you will not be granted access to the system.
Verify your identity by visiting your private email inbox. You should have received an email from the Lorentz Institute Identity Provider 1). Open that email and copy (for instance using on most platforms Control-C or right-mouse click copy) the secret code in the body of the message. Visit https://www.lorentz.leidenuniv.nl/idp/ and paste (on most platforms Control-P or right-mouse click paste) the secret code in the white text area. Click on `Submit'. Your identity is now verified.
Click on Back to application to redirect your browser to the Lorentz Institute SSO web application from which you started the whole process or close the browser. Your setup is complete.
