To see what number of passwords are given away without spending a dime, the only 1,261.4 MB file within the picture above contained over 64,000 credential pairs.
There are hundreds, if not a whole lot of hundreds, of equally leaked archives being shared on-line, leading to billions of credentials information launched without spending a dime.

Related credential collections had been launched up to now, such because the RockYou2024 leak, with over 9 billion information, and “Colection #1,” which contained over 22 million distinctive passwords.
Regardless of the excitement, there is no proof this compilation accommodates new or beforehand unseen information
