The app uses Secure Hash Algorithm 256 (SHA-256) to check for compromised passwords. The attacker may learn the time where the victim’s account was created, guess the timestamp in seconds, apply the Kaspersky algorithm and get the password right in four or five attempts if they’re lucky. For additional security, Kaspersky Password Manager checks whether your passwords have been hacked or leaked. Learn more What is password brute-forcing Trying out all possible combinations of characters until the correct answer is found. ![]() We do not collect or store your passwords. Even if logon attempts are limited and the database never leaks, the password is still at risk. Password Check Kaspersky Check your password Your password is not safe if it can be brute-forced or found in a database of leaked passwords. In other words, if a database of Kaspersky-generated passwords is ever leaked, consider them easily brute-forced, no matter what. Select your language and start your installation. So hashing isn’t going to help much here as well. Installing Kaspersky Password Manager is easy 1 Download & install 2 Create your main password 3 Add your passwords Download the installer from this page. But not if the space of possible passwords is as tiny as in the Kaspersky case. Hashing passwords, if done properly, will buy you some time against an offline brute-forcer. So you can assume that the decryption key is going to ship along with the leak. That’s because if a service keeps passwords encrypted at rest, decryption keys may be available to the system at runtime. Encryption is irrelevant when your threat model involves a leaked user database. (You can tell how rampant the problem is: use unique email addresses per service, wait a year or two, and check how much spam you get on those addresses.) It happens all the time, even though many businesses don’t admit it. ![]() For internet-facing systems, your threat model should acknowledge that the user database is going to leak.
