Hi @Madhumita.Subramaniam,
Thanks for your attention.. I done two test:
1. I added "2fa_requisite" property on OTP only. And I didn't have success.
2. I added "2fa_requisite" property on OTP, Super Gluu and Casa, but also didn't have success.
The Gluu Casa not forced enroll a 2FA. I attached print with the new properties and a GIF logging process.
