Activity Timestamps
Cryptlex records when a license, an activation, or a user was last active. These four timestamps live on three different entities and are updated by different events, so pick the one that matches the question you are answering. All of them are shown on the corresponding pages in the admin portal and returned on the entity in the Web API.
| Timestamp | Entity | Updated when |
|---|---|---|
lastUsedAt | License | Any activation of the license is created, updated, or successfully synced |
lastSyncedAt | Activation | That specific activation successfully syncs with the Cryptlex servers |
lastSeenAt | User | An activation linked to the user successfully syncs |
lastLoginAt | User | The user logs in to the customer portal |
lastUsedAt
lastUsedAt is maintained at the license level and represents the most recent activity across all activations associated with the license. It is updated whenever an activation is created, updated, or successfully synchronized with the Cryptlex servers. For a license with multiple activations, the value reflects the most recent activity among all of them, so it tells you whether the license is in use at all, not which machine used it.
lastSyncedAt
lastSyncedAt is maintained at the activation level and indicates when that specific activation last successfully synchronized with the Cryptlex servers. Unlike lastUsedAt, which aggregates activity across a license, lastSyncedAt reflects the synchronization status of an individual activation, which makes it the field to check when you are diagnosing a single machine.
lastSeenAt
lastSeenAt is maintained at the user level and indicates the most recent time a user was observed using an application associated with their account. It is updated when a license activation linked to the user successfully synchronizes with the Cryptlex servers, which makes it useful for tracking recent end-user activity across your licensed applications.
lastLoginAt
lastLoginAt is maintained at the user level and indicates the most recent time the user successfully signed in to the customer portal. It is updated on successful portal authentication, so you can use it to track customer portal access.
