Is 2fa required for Coinbase?

Hey there, I'm curious about the security measures Coinbase takes to protect its users' accounts. Specifically, I'm wondering if two-factor authentication, or 2FA, is a requirement for accessing a Coinbase account? I've heard that 2FA can add an extra layer of protection against unauthorized access, so I'm interested in knowing if it's a necessary step when using Coinbase. Can you shed some light on this for me? Thanks!
