Every event is associated with a user.

Set user

When a user visits your application for the first time they are assigned a random user id that is stored as cookie, this ID always starts in smu_ and you will be able to see those in your dashboards.

However, you can also set that user yourself, e.g.: if your application requires authentication or it runs in an environment where the user is already authenticated (e.g.: Posit Connect).


tracker <- Shinymetrics$new()$track_recommended()

ui <- fluidPage(
  actionButton("login", "Log in")

server <- function(input, output, session) {

  observeEvent(input$login, {

shinyApp(ui, server)

Note that, like the default username created by shinymetrics, this is also stored as cookie so there is no need to set the user at every session.

If you are using Posit Connect you should be able to access the authenticated user from the session object with session$user.

Unset user

You can always remove that user tracking with shinymetrics_unset_user. This will remove the current user cookie and set it back to any anonymous user (ID starting in smu_).
