In JohnCoene/firebase: Integrates 'Google Firebase' Authentication Storage, and 'Analytics' with 'Shiny'

knitr::opts_chunk$set(
  collapse = TRUE,
  comment = "#>"
)

In the latest version you can also allow signing in with mobile phone numbers.

Enable

Remember to enable this sign in method in your Firebase console.

1. Verify

First, collect the user's phone number and the recaptcha. To collect the capta, simply place recaptchaUI where you want it to display. Note that it will apply only after you run the verfify method (see below).

2. Confirm

Once the verify method has run the user receives a confirmation code that you must also capture and pass to confirm to confirm the authentication. The user is then automatically logged in.

Example

This is an overly simple, ugly example, but fully-functioning.

library(shiny)
library(firebase)

ui <- fluidPage(
    useFirebase(),
    textInput(
        "number",
        "Number"
    ),
    actionButton("verify", "Verify"),
    recaptchaUI(),
    textInput("code", "Code"),
    actionButton("confirm", "Confirm")
)

server <- function(input, output, session) {
    f <- FirebasePhone$new()

    observeEvent(input$verify, {
        f$verify(input$number)
    })

    observeEvent(f$get_verification(), {
        print(f$get_verification())
    })

    observeEvent(input$confirm, {
        f$confirm(input$code)
    })

    observeEvent(f$get_confirmation(), {
        print(f$get_confirmation())
    })
}

shinyApp(ui, server)
