Specifying to Generate Usernames and Passwords with Subscribe Buttons
Do one of following to add Subscribe buttons to your website that generate usernames and
passwords automatically for subscribers:
 Specify that you want PayPal to generate usernames and passwords when you create
Subscribe buttons by using the creation tool on the PayPal website.
See Step 8 of “Step 1 – Specifying Basic Features of Your Subscribe Button” on page 149.
 Specify that you want PayPal to reattempt failed recurring payments in the HTML button
code that you write manually.
See “Sample HTML Code for a Subscribe Button with Password Management” on
page 169.
Reattempting Failed Recurring Payments with Subscribe Buttons
PayPal cancels subscriptions when recurring payments fail. A recurring payment fails if funds
cannot be moved from the subscriber’s PayPal account to your own. Limits on the availability
of funds in PayPal accounts occur rarely, for a variety of reasons.
