How do I force new policies to apply to all LastPass users immediately?

Policies are not applied retroactively, so users need to log out and log back in for any new policy updates to take effect on their account

About this task:

Only LastPass admins can force all users active sessions to end, forcing them to log back in so the new policies will take effect. To end all user sessions in your organization so new policies can take immediate effect, do the following:

Log in with your email address and master password to access the new Admin Console at https://admin.lastpass.com.
If prompted, complete steps for multifactor authentication (if it is enabled for your account).
Go to Users > Users.
In the top row select the checkbox next to Email, then click the option Select all users in your organization.
Go to More actions > Destory all sessions.
Click Destroy sessions to confirm.

Results: All users are logged out of LastPass. Once the users log back in any new policies added will take effect immediately.
