FortiToken Cloud offers five time-based licenses that you can choose from based on your needs.
Suppose that you start FTC service on August 1, 2021 with a 500-user license (i.e., FC3-10-TKCLD-445-01-12) which expires on August 1, 2022. On October 15, 2021, you decide to add 100 more end-users to your account, so you purchase another license for 100 end-users (i.e., FC2-10-TKCLD-445-01-12). Those two licenses are independent of each other. The 500-user license will expire on August 1, 2022, and the 100-user license will expire on October 15, 2022.
You can also renew your existing time-based license by requesting a co-termed license. For example, on December 1, 2021, you want to add a 25-user license and you want it to expire on the same date as your 500-user license does. In this case, the new co-termed license will be stacked on top of the original 500-user license. The cost of new license will be prorated so that it expires on August 1, 2022 as the original 500-user license.
In the first case, the new license is independent of the original license and you can purchase it the its SKU. In the second case, you will have to reach out to our license renewal team (email@example.com) for assistance.
