Trying to register but it requires me to complete 2fa, which make me didn't process further. I don't think anyone would complete it only to testing it and I believe that what might others didn't process further to test your site. Try to make a less strict registration process, so maybe anyone wants to play around testing your site.

Also, I noticed the form on the top of "Find Parking Space" page overlayed each other. It happens on 1366x768. Clicking a parking spot multiple times returns an excessive toast message, maybe try a workaround for it. And it may be a good idea if you linked the signup/in the link on the toast message.
