In plain English: When you log into Deezer via a browser, the website generates a unique token—a long string of random characters—that tells Deezer’s servers, "Hey, this is a valid, paid HiFi user. Let them stream."
In the context of Deezer, ARL (Access Rights Language) is a unique authentication token stored in your browser's cookies. It acts as a digital session key that tells Deezer who you are and what your subscription level is. What is Deezer HiFi? Deezer HiFi is the platform’s high-fidelity tier that provides lossless audio streaming in FLAC format at 16-bit/44.1 kHz (CD quality). Since early 2022, this high-quality standard has been automatically included in most Premium, Family, and Student plans. Why People Use ARL Tokens Because Deezer does not officially support many third-party apps, enthusiasts use ARL tokens to bridge their accounts with external tools. These tokens allow users to: Integrate with third-party software like Music Assistant . Download FLAC files for offline use through community-developed tools like Deemix, ReFreezer, or Murglar. Access HiFi features on devices or applications that aren't officially supported. How to Manually Find Your ARL Token If you have a Deezer account and want to use its token for a third-party application, you can extract it through your web browser's developer tools. Log in to your account at deezer.com . Open Developer Tools deezer hifi arl
Streaming via a CLI tool? Fine. Using your ARL to download 10,000 FLACs to seed on a torrent site? That hurts the artists and will get your account banned instantly. In plain English: When you log into Deezer
Let’s get technical for a moment. ARL stands for (or in some circles, simply "Authentication Request Link"). What is Deezer HiFi
Tracks are encoded in 16-bit/44.1 kHz FLAC , providing CD-quality sound that retains all original data from the recording.
Unlike standard login methods that require a username and password to be sent to a server for verification, an ARL acts as a persistent "session key." When a user logs into Deezer via a web browser, the server issues an ARL token. This token is stored as a cookie, allowing the user to stay logged in without re-entering credentials every time they visit the site.
Many audiophiles prefer using third-party music players (such as deemix, Deezer RPC, or custom integrations in software like Poweramp) because they offer features or interfaces superior to the official Deezer app. However, Deezer does not provide a public API that easily allows these third-party apps to log in via username/password (OAuth). To bypass this, developers reverse-engineered the web player’s authentication process. By extracting the ARL token from a web browser and inputting it into a third-party app, users can access their Deezer HiFi library without using the official, often bloated, Deezer client.
