`} />
### createNewAuthenticatedSession
\RequestContext, user: User, authenticationStrategyName: string, sessionToken?: string) => Promise<AuthenticatedSession>`} />
Creates a new [AuthenticatedSession](/current/core/reference/typescript-api/entities/authenticated-session#authenticatedsession). To be used after successful authentication.
### createAnonymousSession
\ Promise<CachedSession>`} />
Create an [AnonymousSession](/current/core/reference/typescript-api/entities/anonymous-session#anonymoussession) and caches it using the configured [SessionCacheStrategy](/current/core/reference/typescript-api/auth/session-cache-strategy#sessioncachestrategy),
and returns the cached session object.
### getSessionFromToken
\ Promise<CachedSession | undefined>`} />
Returns the cached session object matching the given session token.
### serializeSession
\AuthenticatedSession | AnonymousSession) => CachedSession`} />
Serializes a [Session](/current/core/reference/typescript-api/entities/session#session) instance into a simplified plain object suitable for caching.
### setActiveOrder
\RequestContext, serializedSession: CachedSession, order: Order) => Promise<CachedSession>`} />
Sets the `activeOrder` on the given cached session object and updates the cache.
### unsetActiveOrder
\RequestContext, serializedSession: CachedSession) => Promise<CachedSession>`} />
Clears the `activeOrder` on the given cached session object and updates the cache.
### setActiveChannel
\CachedSession, channel: Channel) => Promise<CachedSession>`} />
Sets the `activeChannel` on the given cached session object and updates the cache.
### deleteSessionsByUser
\RequestContext, user: User) => Promise`} />
Deletes all existing sessions for the given user.
### deleteApiKeySession
\RequestContext, apiKey: ApiKey) => Promise`} />
Deletes session related to API-Key
### deleteSessionsByActiveOrderId
\RequestContext, activeOrderId: ID) => Promise`} />
Deletes all existing sessions with the given activeOrder.
### triggerCleanSessionsJob
\ `} />
Triggers the clean sessions job.
### cleanExpiredSessions
\RequestContext, batchSize: number) => `} />
