Some friends around me have encountered such a situation. It should be that you registered an account for winning the staging platform and then won a short message from the staging platform. If you want to take it, you have cooperated with Fada and accessed their electronic contract service. So when you register the installment account, you will have the Fada account and a digital signature certificate provided by them, which is mainly convenient for you to use when you want to buy goods on the platform. Of course, you can also use it to sign electronic contracts at the University of France. You can go to official website to experience the service of electronic contract and have three free opportunities. It's really great. Do it directly on the internet. I used to deliver express delivery all the time. I'm exhausted.

Generally speaking, it won't affect you, so don't worry.
