It is possible to create monitors using MFA currently with DejaClick. The process for doing so depends on the nature of the Multi-factor authentication requirement.
Using JavaScript Validations in DejaClick you can create a means to auto-answer personal identity verification questions, or send a code via email that is used to validate a login. Both require some custom code, and AlertSite Support can walk you through the process.
We are also working on ways to automate this on the back end to make creating these monitors easier. Support can assist with this for now if needed. Just reach out to alertsite-support@smartbear.com or submit a request once you log into the portal under the "Question Mark" (?) in to top right corner of the console.
