Can we please sign in normally?

Dear Miro team, 

I use Miroboard in my classroom at school but there is something that is rendering the website unusable for me. Every time I try to log in, the website sends a link to my email for me to be able to sing in. This consistently takes 2-3 minutes of waiting for the email to show up in my inbox. even 1 minute is too much in a classroom of more than 30 students who are waiting to see the board. can you PLEASE add the feature of being able to sing in normally with a password or 2FA? 
Being able to preserve the same board for all my different classrooms saves valuable time to start the lesson. teaching is already hard enough. please help.

Looking forward to hearing from you.
