How do I pay with Coinbase?

Could you elaborate on the process of making payments with Coinbase? As a user, I'm interested in understanding the steps involved from setting up an account to actually initiating a payment. Specifically, I'd like to know if there are any verification processes required, what types of payments are supported, and any potential fees associated with using Coinbase for transactions. Additionally, I'm curious about the security measures Coinbase takes to protect users' funds and personal information. Could you provide a detailed breakdown of the payment process using Coinbase?
