Sharing your Netflix password could soon be much harder to get away with.

Most of us are using someone else's Netflix account or are letting their friends or even ex's leech off you Netflix.

The streaming service could be set to crack down on password sharing with a new piece of software.

Software company Synamedia unveiled the new system at CES 2019 in Las Vegas, which will be able to analyse factors such as where users are logged on, and through this, flag shared accounts.

Don't panic if you're just sharing with family and friends, as Netflix may just nudge you to upgrade to a premium account.

So how does it work?

The streaming service buys access to Synamedia’s platform, which analyzes data from all its users.

It takes into account a range of factors, like where an account is being accessed from, what time it’s used, what content is being watched and by what device, etc.

It then looks for patterns that indicate a shared password, and it gives the service provider a probability score — a guess at how certain the system is that it’s found an infringer.

Fingers crossed we can stay watching on our ex's account for a little bit longer!
