Requesting a token with a template name returns a token signed for that template rather than the default session token, with claims built from shortcodes referring to the user and session and a lifetime you configure. This is how services like a database with row-level security get a token they can verify independently.

Use templates instead of stuffing application data into session claims. The session token travels on every request and has a size ceiling, and oversized claims fail in ways that are hard to attribute. Two operational notes: templates are per-instance, so one created in development does not exist in production, and a template token is still tied to an active session and stops working when that session ends.
