How do I sign up for Coinbase?

As a curious investor seeking to navigate the world of cryptocurrency, I'm wondering about the process of signing up for Coinbase. Could you elaborate on the steps required to get started? I've heard Coinbase is a trusted platform, but I'm still unclear on the specifics of the registration process. Do I need to provide any personal information or verification documents? How secure is the sign-up process, and what measures does Coinbase take to protect its users' data? Additionally, how long does it typically take to complete the sign-up and start trading on Coinbase? Your insights would be greatly appreciated as I embark on this journey into the world of digital currency.
