To start using Castor, you need to first create an account. This is completely free of charge. Learn how to register in Castor by following the steps below. This topic is also covered by our workshop material, which can be found here.
You can register a Castor account in two ways:
- Using the Castor EDC website: To register via the website, navigate to the login page via the Castor EDC website or directly go to data.castoredc.com/register. Click the 'New to Castor? Register here' button to access the registration page and create your Castor account.
- By following an invitation link sent to your email when a study admin adds you as a user to their study: If you have received an invitation to a study in your email, clicking on the emailed link will redirect you to the registration page.
Adding Account Details
Registration in Castor is easy - just complete the registration form:
- Server - In Castor, we have servers available in the Netherlands, UK and US. You can choose where the data of the studies you create will be stored. If you are invited by another user to participate in a study, the link in the invitation email should direct to the relevant server location by default.
- First name/last name - This will be also be displayed as your Castor username.
- Email address and password: Enter your email address and choose a strong password. Your password must be eight or more characters in length, and include at least one uppercase letter, one lowercase letter and a number.
- Once all fields are complete, click the 'Register' button to finish and create your Castor account. This will send an activation email to the email address you provided previously. The activation link in this email is only valid for 30 days, so we advise verifying your email address right away. If you don't receive the activation email, we recommend that you check your spam/junk folder.
Log into Castor
Once your account is activated, you can log into Castor.
In the login screen, you are given the option to choose which server you want to log on to, and your Castor account credentials are valid for all servers. This is relevant if you have data on multiple servers (e.g. if you are participating in two studies, one located on the UK server, the other on the Dutch server). The server that is selected by default depends on the url where you are located:
- US server - https://us.castoredc.com
- UK server - https://uk.castoredc.com
- NL server - https://data.castoredc.com
If you were invited to a study by another user and do not have your own study, then you should leave the server location as it is. It is recommended to bookmark your preferred server location, as this will allow you to login without needing to change the server location.
Irrespective of the server you select during login, you will be able to see all of the studies you are participating in on your 'My studies' page. It's important to note that if you access a study that is located on a different server from the one you logged in to, you will be redirected and will need to log in again to access the correct server.
