So I tried transferring my eth in coinbase thru changenow.io over to my okx wallet and tried to send a minimal amount just to confirm and it did go thru. Then I tried sending a larger amount and I got a scammer alert. Coinbase asked for my credentials and asked a certain amount of questions to verify and I did it! But they make it difficult to get your crypto that way. I figured they'd rather you transfer back to your bank to get the fees they charge for the process. So I just did it that way instead. Wanted to share this experience to save you from the hassle.
