If you're using an app that has some special security requirements, you might be required to sign in to IdentityNow before you can use those pages.
For example, if you need to e-sign a document, your company wants to be extra cautious that you are who you say you are before you can even see the e-signature page.
This behavior, known as forced authentication, is similar to strong authentication. The main difference is that while strong authentication uses a variety of verification methods, force authentication always requires you to sign back in to IdentityNow.
NOTE: If you usually don't see the sign in page, you'll probably need to use your network or Active Directory credentials to sign in.
