Add "Enforce Password History" on Website and Console Security Settings
How it works:
When you set this option, the system stores a certain number of your past passwords, and when you try to set a new password that matches one of those stored, it will not allow you to do so.
Configuration:
You can usually set the number of past passwords to remember, meaning how far back the system checks when you try to set a new password.
Importance:
Using Enforce Password History is a crucial security measure to prevent someone from easily guessing your password by trying previously used ones if they gain access to your old login information.
