Patreon is adding Extra Security Steps for EU Patrons (Patreon)

I'll tell you what Patreon told me:  

A new EU law is going into effect this month that will require Patreon to add an extra security step for EU patrons. This is to reduce fraud for card holders, and all companies with EU customers are required to comply.

As a result, some of you may see a pop-up from your bank when pledging or updating payment methods that requests a username and password, a code sent to email or text, or any other authentication method supported by your bank. If you have any questions or issues with one of these popups, it’s best to contact your bank directly, as Patreon does not control the form.
