How do I purchase or renew LastPass Enterprise/Teams?
Just getting started? Sign up for a Trial. To purchase LastPass Enterprise you must start with a trial. You can sign up for the trial at https://lastpass.com/enterprise_trial.php . You will be prompted to purchase licenses for Lastpass Enterprise at the end of your trial or you can purchase licenses immediately.
Purchase Licenses. If you would like to purchase initial or more licenses throughout the year, go to the Home Page of the Admin Console and follow the 'BUY LICENSES' link at the top right corner. Initial purchases will show the full price, any additional licenses purchased throughout the year will be at a prorated rate so that all licenses expire at the same time as your initial purchase.
Renew Licenses. Enterprise licenses do not renew automatically, and must be done so by the Admin. You can renew the desired license amount by going to the Home Page of the Admin Console and clicking the 'BUY LICENSES' button. 'Renew Now' option is only available in the last month of your Enterprise contract.
Note that only Enterprise and Teams Administrators can purchase more licenses. Direct link to the Admin Dashboard: https://lastpass.com/enterprise_home.php (Enterprise accounts) and https://lastpass.com/teams/#/dashboard (Teams accounts).
