shinymanager : SQLite Admin

Introduction

Using SQL database protected (create_db()), an admin mode is available to manage access to the application, features included are

# Credentials data
credentials <- data.frame(
  user = c("shiny", "shinymanager"),
  password = c("azerty", "12345"),
  # password will automatically be hashed
  admin = c(FALSE, TRUE),
  stringsAsFactors = FALSE
)

# you can use keyring package to set database key
library(keyring)
key_set("R-shinymanager-key", "obiwankenobi")

# Init the database
create_db(
  credentials_data = credentials,
  sqlite_path = "path/to/database.sqlite", # will be created
  passphrase = key_get("R-shinymanager-key", "obiwankenobi")
  # passphrase = "passphrase_wihtout_keyring"
)

# Wrap your UI with secure_app, enabled admin mode or not
ui <- secure_app(ui, enable_admin = TRUE)


server <- function(input, output, session) {
  
  # check_credentials directly on sqlite db
  res_auth <- secure_server(
    check_credentials = check_credentials(
        "path/to/database.sqlite",
        passphrase = key_get("R-shinymanager-key", "obiwankenobi")
        # passphrase = "passphrase_wihtout_keyring"
    )
  )
  
  output$auth_output <- renderPrint({
    reactiveValuesToList(res_auth)
  })
  
  # your classic server logic
  ...
}

Starting page of the application will be :

Once logged, the application will be launched and a button added to navigate between the app and the admin panel (if user is authorized to access it), and to logout from the application :

Admin mode

Manage users

The first table lists all current users :

A user is defined (at least) by the following information :

Add user

Using Add user button. So you can edit user information in the modal box :

Notes :

  • User : Canno’t create existing user
  • Start & Expire : Keep empty for no restriction
  • Password : By defaut, a temporary password is generated. But you can put your own password and disable asking user to change it on first connexion.

Finally, the creation is effective clicking on validation button.

Edit current user

It’s possible to edit user information clicking on the blue button on the table.

Remove a user

You can remove one user using red button on table.

Password management

The second table allows password management :

  • Change password button : Ask user to change password on next connexion
  • Reset password button : If needed, a nex temporary password is generated. You have to give it to the user.

Moreover, by defaut, the module uses some security rules :

  • at least 6 character
  • one number, one uppercase, one lowercase

Additive information :

  • Must change : The user have to change his password
  • Have changed : The user already changed his password
  • Date change : Password updated date

Logs

You can visualize and download connexion logs on the second tab.
