Just had this from Stripe:

Learn how the Strong Customer Authentication regulation affects your business and how to update your integration to prepare for it.

Quote

Strong Customer Authentication (SCA), a new rule coming into effect on September 14, 2019 as part of PSD2 regulation in Europe, will require changes to how your European customers authenticate online payments. Card payments will require a different user experience, namely 3D Secure [2], in order to meet SCA requirements. Transactions that don’t follow the new authentication guidelines may be declined by your customers’ banks.

Is this something that needs to be updated/integrated into Commerce?

We're aware and will be updating our integration in a future release. 🙂 

Thank you. Top-notch support from Invision – as always!

Any idea when this update may be coming been looking for a longterm solution to this issue for a while! Thank you!

Before the deadline. It's on our radar - in the mean time, there's no need to worry about it.

I came to ask the exact same question. Thanks for getting back to us.
