What is an insecure practice when managing online logins?

Having the same password for multiple accounts is considered an insecure practice when managing online logins because it increases the risk of unauthorized access to those accounts. If a cybercriminal successfully obtains one password through a data breach or phishing attack, they can exploit that password across all accounts that share it. This can lead to severe ramifications if any of those accounts contain sensitive information, such as financial data or personal identifiers.

In contrast, utilizing a password manager, writing passwords in a secure location, and maintaining different passwords for different sites are considered secure practices. A password manager can create and store strong, unique passwords for each account, making it easier for users to manage their logins without resorting to weaker, shared passwords. Writing passwords in a secure location ensures they are not easily accessible to potential intruders, while using different passwords helps mitigate the risk associated with any one password being compromised.
