To change your Linktree username, first, log in to the Linktree app. Navigate to your profile settings. Here, you will find an option to change your username. Keep in mind, your username should be unique, so if the one you want is taken, you'll have to choose another. Changing your username also changes your Linktree URL, as they are directly tied to each other. You can also get a free branded link from Linklab with the username of your choice in the link.
