How do I authenticate my Coinbase account?

As a cryptocurrency enthusiast, I'm curious about the process of authenticating my Coinbase account. Could you please elaborate on the steps involved? I've heard that security is paramount in this space, so I'd like to ensure I'm taking all the necessary measures. Specifically, I'm wondering if I need to provide any personal identification documents, and if there's a specific verification process that I need to go through. Additionally, are there any common mistakes that people tend to make when authenticating their accounts, and how can I avoid them? Thank you for your assistance in navigating this important aspect of crypto finance.
