What Jellyfin Is and Why Usernames Matter

Jellyfin is a free media server software that lets you store and watch your own movies, TV shows, music, and photos from any device connected to your network or the internet. Unlike subscription streaming services, Jellyfin runs on your own hardware—a computer, server, or even a Raspberry Pi—and gives you complete control over your media library. Since Jellyfin is self-hosted, managing who can watch what content falls entirely on you as the server administrator.

Usernames form the foundation of Jellyfin's access control system. Each person who watches content on your Jellyfin server needs a username to log in. Think of a username as a unique identifier that tells Jellyfin who is trying to watch something. Without usernames, there would be no way to track viewing history, set individual preferences, or control what content different people can see. A username might be as simple as "sarah" or "bedroom-tv" or "kids-account." The choice is yours.

Understanding how usernames work is the first step toward setting up a secure and organized Jellyfin system. Different users can have different permissions, different content visibility, and different restrictions based on their age or preferences. Parents might create separate accounts for children with limited content options. Friends or family might have accounts that only show specific shared folders. Understanding these basics helps you set up your server the way you actually want it to work.

Jellyfin stores username information in a database on your server. When someone enters their username and password, Jellyfin checks that database to see if the account exists and if the password matches. This happens entirely on your own hardware—no information goes to a company or third party unless you specifically configure it that way. This local storage is one reason Jellyfin appeals to people who want privacy and control over their media access.

Practical Takeaway: Before creating usernames, think about who needs access to your Jellyfin server and what role each person plays. Are they family members who should see all content? Guests who visit occasionally? Household members with different age-appropriate content needs? This planning makes creating and managing usernames much more straightforward.

Creating and Managing Jellyfin Usernames

Creating a new Jellyfin username requires administrator access to your server. The administrator is the person who initially set up Jellyfin and has full control over all settings and users. If you set up the server, you already have administrator status. To create a new user, you log into Jellyfin's administration interface—usually accessed through a web browser—and navigate to the user management section. There you will find an option to create a new user, typically labeled "Add User" or similar.

When creating a username, Jellyfin has a few basic requirements. The username must be unique—no two users can have the same username on the same server. Usernames are typically between 1 and 55 characters long, though shorter names are generally better for daily use. You can use letters, numbers, and some special characters, though most people stick with simple alphanumeric usernames to avoid confusion. For example: "john," "bedroom-tv," "guest-account," or "sarah-phone" all work fine.

After entering the username, you set a password for that account. Jellyfin requires passwords, and they function as the second layer of security after the username. The person using that account will need to enter both the username and password when logging in. You can change this password later from the admin interface if someone forgets it or if you want to reset it for security reasons.

Jellyfin also lets you set a PIN code as an alternative to passwords for certain clients or situations. This is useful if someone wants to watch content on a smart TV app but typing a long password is inconvenient. You can set a 4-digit PIN that works alongside or instead of the regular password, depending on your configuration. This gives flexibility in how different users log in from different devices.

Managing usernames involves keeping track of who has accounts, updating passwords periodically, and removing accounts for users who no longer need them. You can edit any username's settings from the admin panel. If someone no longer watches content on your server, you can delete their account entirely, which also removes their viewing history and preferences from the database.

Practical Takeaway: Create usernames that are easy to remember and easy to type. "sarah" is better than "sr4h_92x" because people actually remember it and can type it quickly on any device. Keep a private list of all usernames and which people they belong to so you can manage them effectively.

Understanding User Roles and Permissions

Jellyfin has different types of user roles, and each role comes with different permissions that control what that user can do on the server. Understanding these roles is essential to setting up an organized system. The main roles are Administrator, User, and Guest, though the specific naming and options may vary depending on your Jellyfin version.

An Administrator account has full control over the entire Jellyfin server. Administrators can create and delete other users, change settings, manage libraries, and see all content. Your main account—the one you created when you first set up Jellyfin—is an administrator account. Most servers only need one or two administrator accounts. It is generally not a good idea to make every user an administrator because they would then be able to change important settings or delete accounts.

A regular User account is what most people have. Users can log in, view content based on what the administrator has given them permission to see, watch shows and movies, and maintain their own viewing history and preferences. Users cannot change server settings, create new users, or modify permissions. This is the appropriate role for family members, friends, or guests who simply want to watch your media content.

Guest accounts are sometimes available and offer limited permissions. A guest user might be able to see only certain libraries or content folders. You might create a guest account for a friend visiting for a few days who should watch movies but not access personal or sensitive content folders. Guest accounts can sometimes be set with expiration dates, meaning they automatically stop working after a certain number of days.

Beyond the user role itself, administrators can set many specific permissions for each user. These permissions control things like whether a user can access a specific library, whether they can delete or modify content, whether they can see certain content types, and whether they can use remote access from outside the home network. Permissions are set in the user's individual settings page in the admin interface.

Practical Takeaway: Assign the Administrator role only to people you trust completely and who need to manage the server. Give everyone else a User role unless they specifically need limited Guest access. Review permissions regularly to make sure each user can access what they should and nothing they shouldn't.

Setting Up Content Access Controls by Username

One of the most powerful features of Jellyfin's username system is the ability to control what content each user can see. This is different from user roles. While roles control what actions a user can perform on the server, content access controls determine which movies, shows, music, and photos each individual user can view. You might have one username that sees your entire media library, another username that only sees family-friendly content, and a third username that only sees certain music folders.

To set up content access controls, you first need to organize your media into libraries within Jellyfin. A library is a collection of content—for example, you might have a "Movies" library, a "Family Shows" library, a "Personal Videos" library, and a "Music" library. Within each library, you have folders and subfolders containing actual content files. Once libraries are set up, you can use the user settings to control whether each username can see that entire library.

For each username, you can specify which libraries that user has permission to view. You might give your main account visibility to all four libraries. A child's account might see only "Family Shows" and "Music." A guest account might see only "Movies" and "Music." This prevents children from accidentally seeing adult content and prevents guests from seeing personal or private videos. The access control happens at the username level, so it is specific to each individual account.

Beyond library-level permissions, Jellyfin supports content ratings and parental controls. You can set a maximum rating level for each user—for instance, a child's account might be restricted to content rated G and PG, automatically hiding anything rated PG-13 or R. This works if your media is properly tagged with ratings in the metadata. The restriction is set for that specific username
