yeah i remember when I first signed up that confused me too.. i never use the online portion.. I just tried to log in online but i only saw my bitpay debit card.
here's what it says on the website:
Why don't I have an online account for my BitPay wallet?

FollowYou do not need an account on
bitpay.com to use your BitPay Wallet. Your BitPay Wallet is secured using your device and your private key: by design, BitPay
never has access to your bitcoin or your wallet.
Have you backed up your BitPay Wallet? It's extremely important that you do so.
If you don't set up a backup and lose your wallet (hard drive failure, theft, etc.), then the funds inside will not be able to be recovered. (Note that this is true for all bitcoin wallets.) See:
https://support.bitpay.com/hc/en-us/...ore-my-wallet-
We have a guide on how to back up your wallet
here in this help articles as well as a
video guide.
You don't need a second device, you just need to copy down the recovery phrase and keep it somewhere safe. Please don't do anything like email it to yourself or keep a copy on the device where your Wallet is. If you do this and then your device is stolen, then the thief would be able to steal your wallet's funds as well.
