The IDOL Community component provides several security options for user accounts.
In addition to passwords, you can assign PIN codes to users for authentication with Community
You can set a minimum length for user names and passwords, and a minimum strength for user passwords.
You can also specify how often users must change passwords and PIN codes, and ensure that they do not use the same passwords again.
You can set up Community to protect against brute force attacks. Community can lock user accounts if there are too many incorrect logon attempts from a user in a certain time period.
