Here are some of the ways Netflix might enforce password sharing:
Technical measures include:
Geolocation: can track the IP address of devices that are accessing its service. If a device is located outside of the account holder’s home country, Netflix may prompt the user to verify their password.
Device ID: can also track the device ID of devices that are accessing its service. If a device is not listed on the account holder’s account, Netflix may prompt the user to verify their password.
Account activity: can also track the account activity of its users. If an account is being used from multiple locations, Netflix may prompt the user to verify their password.
User-facing measures include:
Emails: may send emails to account holders who are sharing their passwords. These emails will explain the policy and offer the user the option to add additional users to their account.
Pop-ups: may display pop-ups to users who are accessing its service from a location that is outside of their home country. These pop-ups will explain the policy and offer the user the option to verify their password.
IP address tracking: could track the IP addresses of users who sign in to their accounts. If a user signs in from an IP address that is outside of their home country, Netflix could ask them to verify their account.
Device ID tracking: could track the device IDs of users who sign in to their accounts. If a user signs in from a device that is not in their home, Netflix could ask them to verify their account.
Location tracking: could use location data to track where users are signing in from. If a user signs in from a location that is outside of their home country, Netflix could ask them to verify their account.
Payment method verification: this could require users to verify their payment method when they sign in to their accounts from a new device or location. This would help to ensure that only people who are authorized to use the account are able to do so.
