Are you saying you have fund in coinbase multi-sig vault and you are able to withdraw your fund from that just with entering the 2FA code and email verification? How is that possible? As already said, they no longer supports multi-sig vault.
I feel you are confusing coinbase mutli-signature wallet with their custodial wallet.
No, I'm using their vault and I usually use it to save a few sat before it always requires approval in my Coinbase account I can approve the withdrawal from the vault but it is still pending and it needs a 2nd approval by a co-signer/secondary email I receive an email from Coinbase(as a secondary email) and the email asks for my secondary approval with a link when clicking approve I wait for 24hours until the fund's transfer to the main wallet.
Please check the video I provided above that is how I withdraw funds out from the vault.
