Why is password re-use a bad thing?

Using the same password across multiple accounts is generally not a good idea for the following reasons:

Security Breaches: If one account gets hacked, the hacker will be able to access all other accounts using the same password.

Lack of Complexity: It is difficult to create a complex password that is unique for each account. Using the same password may mean using a less complex password that is easier for hackers to guess or crack.

Phishing Attacks: Phishing attacks can trick users into revealing their login credentials. If the same password is used across multiple accounts, the hacker can use the stolen credentials to access all the other accounts.

Personal Information: If a password is compromised, a hacker could use personal information from one account to guess the passwords for other accounts.

Compromised Devices: If a device is lost or stolen, a hacker may be able to access all accounts that use the same password.

Overall, using the same password is risky and could lead to a significant compromise of your online security. It’s always recommended to use unique, complex passwords for each account and enable two-factor authentication whenever possible.
