I was wondering how I could make my cloudflare login page ask for an email,

I would like to have the login ask for an email, and accept a TOPT code right after as a further deterrence

Hey thank you very much, although I have already done this.
However, I do not see the option to add this to login to my tunneled sites. I may just be blind though

Fopr applications protected by Cloudflare Acces MFA would come through your Identity provider and requiring MFA in your Access policy.
