Thank you so much 
I am kind of afraid about Hacking so maybe we will forget it.
I have a question :
Do you think it is possible to send an email (Via Sendgrid) to the User,
He.she clicks on a link to go on the app and we ask him to fill out :
To connect on his/her account.
BUT:
Is it possible to fill the identification with th email directly ? So the User writes onlyt the password ?
Thank you
