Some random form showed up in my account?

I noticed that there is a form that was supposidely created 4 days ago in my account. I want someone to explain to me why a form that is NOT mine is in my account and reassure me that my account is secure.

The form is: https://form.jotform.co/91026562949868

I have checked your account history but the form was not created last week based on your account history.

You may check your account activity logs in your account. Here is a guide:https://www.jotform.com/help/370-How-to-View-Your-Account-Activity-Logs

It seems that within the week the form was modified.

May we know if you have modified the form?

May we know you're the only person who has access to your account?

Looking forward for you response.
