With effect from Friday, the tech giant will delete them because they don’t use their accounts.

The company said it would close accounts that “were created and never used again” in the first step.

To keep an account open, all you should have to do is sign in or send an email.

Google said the change was for security reasons, pointing out that accounts that are forgotten or not used are more likely to be hacked.

People with a Google account can use the same login and password to log in to most Google products, like the email service Gmail and the video sharing site YouTube.

The tech giant said in a blog post in May that old accounts are more likely to be hacked because they use old or reused passwords and don’t have two-factor security set up.

Once someone has hacked into an account, it can be used for anything, from spam and identity theft.

How to keep your account safe
For most people, just logging in should be enough to keep their Google account open for another two years.

You could also read or send emails through Google Drive or watch a YouTube movie, according to Google.

After you log in, it’s helpful to have an easy-to-reach recovery email address linked to your account. That way, you’ll be able to get the alerts.

If you forget your password, you can use the recovery email address to get it back.
