How do I access Aurora?

Could you elaborate on the steps involved in accessing Aurora? I'm interested in exploring this platform but am unfamiliar with the process. What are the initial requirements I need to fulfill? Do I need to create an account or download a specific wallet? Additionally, are there any security measures I should take into consideration before proceeding? It would be great if you could provide a step-by-step guide to ensure a smooth and secure access to Aurora. Thank you for your assistance.
