Overview

Deeztracker Mobile requires a Deezer ARL (Authentication Request Login) token to access and download music from Deezer. This token authenticates your Deezer account and enables the app to retrieve your music.

​
What is an ARL Token?

The ARL token is a unique authentication cookie that identifies your Deezer account session. It allows Deeztracker Mobile to:
  • Search and browse the Deezer catalog
  • Download tracks, albums, and playlists
  • Access your account’s streaming quality settings
Keep your ARL token private. Anyone with access to your token can use your Deezer account through Deeztracker Mobile.

​
How to Obtain Your ARL Token

Follow these steps to extract your ARL token from your browser:
1

Log into Deezer

Open deezer.com in your web browser and sign in to your account.
2

Open Developer Tools

  • Chrome/Edge: Press F12 or right-click anywhere and select “Inspect”
  • Firefox: Press F12 or right-click and select “Inspect Element”
  • Safari: Enable Developer menu in Preferences, then press Cmd+Option+I

5

Copy the ARL Value

Find the cookie named arl in the list. Click on it and copy the entire Value (it’s a long alphanumeric string).
Your ARL token typically looks like a long string of random letters and numbers (e.g., a1b2c3d4e5f6g7h8i9j0k1l2m3n4o5p6q7r8s9t0...)

​

  • Tap the text field labeled “ARL Token”
  • Paste your ARL token (you can use the clipboard paste button)
  • Ensure the entire token is pasted correctly
3

Verify and Log In

  • Tap the “Continue” button
  • The app will verify your token using RusteerService.verifyArl()
  • If valid, you’ll be taken to the main screen
fun performLogin() {
    if (arl.isBlank()) return
    isLoading = true
    errorMessage = null
    scope.launch {
        val success = rustService.login(arl)
        isLoading = false
        if (success) {
            onLoginSuccess()
        } else {
            errorMessage = context.getString(R.string.login_error_failed)
        }
    }
}

  2. Try again in a few minutes
  3. Verify your Deezer account is active by logging in at deezer.com

  • Selected quality exceeds your account permissions
