Password reuse refers to the practice of using the same password for multiple accounts or services. While it may be convenient for users, password reuse poses a significant security risk. If one account gets compromised, all other accounts using the same password are vulnerable to unauthorized access.
Cybercriminals often exploit password reuse by using automated tools to try the same username and password combinations across multiple platforms, a technique known as “credential stuffing.” Once they gain access to one account, they can potentially access other accounts, leading to identity theft, financial fraud, or data breaches.
To avoid the risks associated with password reuse, users should create unique, strong passwords for each account and use a password manager to keep track of them. Enabling multi-factor authentication adds an extra layer of security, making it more difficult for unauthorized individuals to access accounts, even if they have the correct password.
