While any customer can use PayPal to fund their account, new customers will still need to sign up using a credit card. You can use PayPal from then on.
This is in part because we don’t yet have the ability to automatically transfer funds from PayPal. If you intend on paying only via PayPal, you will need to ensure that you have enough credit on your Linode account to cover your next invoice. Otherwise, our system will attempt to collect any remaining balance from the credit card you have on file.
