UK donates 225 million stolen passwords to hack-checking site

UK law enforcement has donated a tranche of 225 million unique passwords to a cyber-security project helping to protect users from hacking.

The National Crime Agency (NCA) recovered the database from cyber-criminals who had collected real users' email addresses and passwords.

That list has been added to free online service Have I Been Pwned (HIBP).

It lets anyone search through hundreds of millions of passwords to see if theirs is in the hands of criminals.

Troy Hunt, the security researcher who runs the site, announced on Friday that it now has a "pipeline" function for law enforcement to add passwords they have recovered to the service.
