2 Factor Authentication for EPM

Hi Experts,

We have a requirement to implement 2 Factor Authentication for EPM. EPM should pop up a screen to enter One time password(OTP) or hard token after user login to EPM with initial pasword. I have found below threads, but these seems be related to GUI/portal.

I would also like to know if portal 2 Factor Authentication will work for EPM or not?

It would be great help, if someone share details of this solution who is already using this solution.

Best Regards
