This month, Netflix stumbled backward into a policy that may have lasting security benefits for users. Its accidental pro-customer safety move could be an object lesson for other business-to-consumer (B2C) organizations looking to improve customer account security.

The streaming giant brought its new “household” policy to US customers on May 23. From now on, accounts will be restricted to a single Wi-Fi network and related mobile devices (with certain exceptions). It’s a shot in the arm to cure a post-COVID hangover, boosting user growth after months of stagnation and investor skittishness.
