IAM password policies should prevent reuse of the four previously used passwords¶
IAM password policies should prevent users from reusing any of their previous 4 passwords. Preventing password reuse increases account resiliency against brute force login attempts.
Navigate to Identity and Access Management.
In the left navigation, select Account Settings.
Check Prevent password reuse.
In Number of passwords to remember, enter 4.
Click Apply password policy.
Set number of passwords to remember to 4.
This operation does not support partial updates. No parameters are required, but if you do not specify a parameter, that parameter’s value reverts to its default value.
