YouTube has introduced an Account Lock feature for its TV app, allowing users to protect their YouTube account on shared television devices with a four digit code.

The feature is designed for people who use YouTube on shared TVs. Once Account Lock is enabled, users will need to enter the four digit code to access their signed-in YouTube account.

According to YouTube’s official support page, the feature can help prevent other people using the same TV from accessing a user’s account and personal YouTube experience.

Users can set up Account Lock through the YouTube app on their TV. The feature is available on supported smart TVs, streaming devices and game consoles.

YouTube says the feature is being rolled out globally. It gives users an additional way to keep their account and personalised YouTube experience protected when using a shared TV.

The Account Lock feature is particularly useful for households, hotels or other places where multiple people may use the same television to access YouTube.
