LMS Admin here:

We would like to turn OFF the authentication services in Canvas (i.e. Google Authenticator/2FA). It is causing issues with international students on so many levels. We are comfortable in removing it but when I select "Remove Authentication" it throws a warning that says "Users may not be able to login" --- SO I need to know what is going to happen if I remove the authentication? Am I going to open the floodgates of issues with people being able to access Canvas?
