How do I validate my users (via periodic validation)?

This is only possible if “periodic validation” is enabled for the organisation.
You can find this option in the ‘user management’ tab – ’employees’ – [click to open user overview] – ‘validate user’

Check (1) whether the user is still employed (2) whether the user still needs access to IAMconnected (3) whether the user’s details are correct:

• Disconnect the user if they are no longer employed or no longer need access.
• Ask the user to change their details if they are incorrect.
• Everything in order? Click on “validate user”.
