[keycloak-user] Is there a possibility to stop users changing their passwords too often?

[Kevin Thorpe]

As Stefan has already said one thing is to stop people changing their
password and putting it straight back. Also for some implementations it's
possible to repeatedly change passwords mechanically and sniff timings to
get an idea of the implementation of the password check policy. In my case
it's simply that we have a large prospective clients who specifically
requested this functionality.
