I made the mistake of opting for this - now I have to go my cell phone every morning to see and quickly enter a 5 number code from the phone to my computer in order to open my email -  then I get a message stating that the code will be unnecessary for 180 (or some such number) days. But the thing shows up again every morning. Does anyone know how to get rid of this thing?  By searching the web, I found a 2018 posting apparently advising going to chrome settings.  However, if you use a chrome-based browser (Vivaldi) that just takes you to the browser's settings.  I have sent an email to Zoho asking for help, but, of course, have received no response.
