A password policy is a set of rules and guidelines that organizations implement to govern the usage, management, and enforcement of passwords. By creating an effective password policy, organizations can protect their systems from unauthorized use or access by providing clear guidance on how passwords should be created, used, stored, and changed.
An example of a password policy might include:
- Passwords must be at least 8 characters long.
- Passwords must contain at least one number or special character.
- Passwords must be changed every 90 days.
- Passwords cannot contain personal information like name or date of birth.
- Reusing old passwords is prohibited.
