What if Coinbase verification process is too long?

As a cryptocurrency enthusiast, I'm concerned about the potential delays in the Coinbase verification process. Could you elaborate on what steps Coinbase takes to ensure security during this process, and why it sometimes seems to take so long? Additionally, what options are available for users who experience prolonged delays in their verification? Is there a way to expedite the process or are there alternative platforms that provide a faster and more efficient verification experience? Understanding these details would help me make an informed decision regarding my choice of cryptocurrency exchange.
