Virtru plugin and app activations expire every 120 days. After any expiration, Virtru will prompt a user to re-activate.
Activations are much like application sessions - signing-out of a session and then coming back to the application later will prompt you to login again. Therefore, whenever you encounter an activation prompt in Virtru, simply reactivate in order to continue sending secure emails.
Expiring a session or app activation after a certain period of time or inactivity is a common software best practice. There are a number of reasons behind this, but security is one of the main factors. We chose to expire the activation every 120 days in order to comply with FedRAMP.
To Reactivate Virtru, go to the appropriate installation article below and follow the instructions in the Reactivation section.
Other Scenarios that Require Reactivation
There are also a few cases where users might be prompted to activate sooner than 120 days:
- If the user clears their browser cache
- If Virtru is uninstalled
- If an already activated user attempts to use Virtru on a new device
Furthermore, if a user receives delegated access to another user's mailbox, the delegatee will be prompted to reactivate every 10 days.
