Your Argos account is for when you shop with Argos. You can use it to log in to our site and make purchases.
Your Argos Pay account is for managing the way you pay for those purchases on finance. You can access it using the Argos Pay app or your Online Account Manager, logging in with your unique Argos Pay username and passcode. This is where you'd go to make a payment towards your Argos Pay balance, view statements and notices, check your payment plan information or change your personal details.
