Is there a requirement to change the password periodically?
The requirement to change passwords periodically varies depending on the policies implemented by the organization or the individual's preference for their personal accounts. In the past, it was a common practice to enforce regular password changes to enhance security. However, current guidelines from many cybersecurity experts suggest that regularly changing passwords may not necessarily improve security and can even lead to weaker passwords being used. Instead, it is generally recommended to use strong, unique passwords and enable multi-factor authentication to enhance account security.
