How to reset autogenerated Kentico passwords on first use?

When you click on the 'Generate new password' button, on Kentico's 'User' application's Password tab.

The password is sent out in clear text via email. We want users to change their password the first time they login. Is there any suggestions on how to achieve this?

We use Kentico 11's with ASPX template and I have access to the code and database. I've checked the documentation and there is no built in setting to do this.

Thanks

Another option would be setting some passwords for the users and then setup either password expiration or password policy - so the passwords will not meet one of these and they will be asked to change the password using the password reset.
