Frequent password changes are essential for safeguarding against unauthorized access to sensitive information because they help mitigate the risks associated with password compromise. Regularly updating passwords reduces the likelihood that an attacker can gain prolonged access to sensitive systems or information using stolen or leaked credentials. This practice is part of a broader strategy known as good password hygiene, which includes creating complex passwords and not reusing them across multiple accounts.

Implementing frequent password changes makes it more challenging for unauthorized users to maintain access, especially if they acquire a password through methods such as phishing or brute-force attacks. This routine can also encourage individuals to create stronger passwords, enhancing overall security posture.

In contrast, sharing passwords compromises security by giving multiple people access to sensitive systems or data, increasing the risk of accidental or intentional misuse. Using simple passwords is inherently insecure because they are easier for attackers to guess or crack. Storing documents in unlocked cabinets presents a physical security risk, as sensitive information could be accessed by anyone in the vicinity. Therefore, frequent password changes play a crucial role in protecting sensitive information from unauthorized access.
