Why should you avoid using the same password across multiple sites?

Using the same password across multiple sites significantly increases vulnerability if one account is compromised. When a password is reused and one site experiences a data breach, cybercriminals can access that password and attempt to use it on other accounts where the same password is employed. This is known as credential stuffing, and it can lead to widespread account takeovers, as many individuals tend to use the same login credentials for various services.

By diversifying passwords and using unique ones for different accounts, individuals can enhance their security and limit the risk of multiple accounts being compromised in the event of a data breach. This is a fundamental practice in maintaining good cybersecurity hygiene, as it helps protect sensitive information and personal data from unauthorized access.
