I am making a quiz app that includes a ranking of schools. When signing-up the user chooses his school.
I would like it to be the less manipulative possible and the most accurate possible. I mean I know it would be impossible to have the databases of all universities e-mail adresses to check if a specific address exists and belongs to one user.
Has anyone found a method to allow the user to use the app only if he belongs to the type he declared?
I tried to make a Collection with all the Universities name and e-mail addresses extensions but I’m stuck when it comes to check if the e-mail that the user entered to sign-in in the form has this extension.
I can only get the e-mail from the logged in user and I want to check the e-mail before the login …
