Protect Yourself From Data Breaches: Why You Should Use a Password Manager | HackerNoon
Briefly

Creating unique passwords for each online account is essential for privacy and security. Many users tend to reuse passwords across multiple sites, which greatly increases vulnerability to hacking. A common tactic involves successfully cracking passwords from one site and using them to access other accounts linked to those credentials. Because the number of passwords required can be overwhelming, especially for users managing hundreds of accounts, a password manager is advised. This tool allows users to remember one strong password that unlocks a vault storing all other distinct account credentials.
Creating unique passwords for each online account is crucial because reusing passwords makes it easy for hackers to access multiple accounts. They often use a method where they crack one website's password and then attempt to log into others using the same credentials. This tactic is commonly successful, as people tend to reuse passwords, leading to significant security risks.
As the number of online accounts increases, so does the need to remember numerous unique passwords. Managing over 500 passwords is impractical, hence a password manager is recommended. This tool requires memorizing only one strong password, which unlocks a vault of unique passwords for each account, significantly improving overall online security.
