Before each payment is due, Affirm sends you an email or SMS reminder with the installment amount that is coming due and the due date. You have the option to sign up for autopay, so you don't risk missing a payment. Follow these steps to make a payment:
1. Go to www.affirm.com/account.
2. Enter your mobile phone number. Affirm sends a personalized security PIN to your phone.
3. Enter this security PIN into the form on the next page and click Sign in.
4. After you sign in, a list of your loans appears, with payments that are coming due. Click the loan payment you would like to make.
5. Make a payment using a debit card or ACH bank transfer.
