If you ever want to force an account to change their password the next time they login, you can do that to multiple accounts at one time. To do this, select View Accounts.

Choose your type of account(s) you want to force the the accounts to change their password for.

Use the search and filtering options to help find the accounts.

Check the boxes next to the names of the accounts you want to force to change their password. The checkbox at the top will select all the checkboxes on the page. There is also a link where you can choose all accounts in the view if you want to do this to everyone.

Select Force Password Reset from the options in the toolbar at the bottom of the screen.

Once selected, all of the selected accounts will need to change their password.

The next time once of these accounts logs in, they will be forced to update their password.
