Dear CROS portal user,
In order to log in to CROS (from a computer outside of the European Commission’s IT environment), you need to have an EU Login account allowing two-factor authentication. That means that you must either register your mobile phone number in your EU Login account or install the EU Login application on your smartphone. See the instructions for doing so at here.
All EU login accounts have to be validated by the CROS portal team. (Until they have been validated, they will be blocked.) From 25 May onwards, please send us a request via the contact form in case your account is still blocked (in order to have your account validated).


What is a hackathon?

Data hackathons, also known as data dives, are intense events where teams of data scientists, computer programmers, graphic and interface designers and project managers try to creatively tackle data problems and prototype data analytics products. Hackathons typically last between a day and a week. Some data hackathons are intended simply for educational or social purposes, although in many cases the goal is to create usable data analytics products. Data hackathons tend to have a specific focus, which can include specific data sources, methodologies, technologies and applications but in other cases, there is no restriction on the type of data analytics product being created.
