A password leak check is performed when you are concerned about your password being in the hands of an unwanted third party. You can use data breach checker tools to see if your password has been leaked.

The mishandling of data by companies, such as flaws in security protocols or hardware, and poor end-user behavior, such as weak passwords, are the leading causes of data leaks. Per the reports of CybSafe, around 90% of breaches in 2019 were brought on by the errors of part of the end users.

Data leaks can range from passwords to real names, to even social security numbers and banking information as well. If this information is in the hands of a hacker, then they can steal your identity, cause frauds under your name, or even ruin your bank account. This can cause a large number of legal issues which are difficult to tackle.

Security tools such as AstrillVPN can help you protect your data by military grade encryption on all types of connection, on a multitude of devices. Other than this, you can take some measures by yourself as well by making stronger passwords, keeping an antivirus software on your device, and by using two factor authentication wherever possible.

Hackers can find loopholes in the security protocols of different companies. They can also hack into their databases and collect information about clients, which can result in a data breach.

You can use data breach checkers to check if your information has been leaked. One such tool is Have I Been Pwned, which checks if your email address is linked to the HIBP database of leaked passwords. The site will then send a query to multiple data breaches to see if your data has been leaked or compromised.
