Discord can’t truly be used “without cookies saving sign-in info” in the browser unless you also avoid normal persistent login storage, because Discord may keep you signed in through browser storage beyond cookies. Discord’s own cookie policy says you can disable or manage some cookies in your browser settings, and users report that Discord can keep session data in local storage, not just cookies.

What to do

  • Use Incognito/Private browsing so the session is discarded when you close the window.
  • Clear site data after each session, including cookies and stored site data for discord.com.
  • In browser settings, block or limit cookies for Discord, then sign in only when needed.
  • If you use the desktop app, log out after each use and clear the app’s saved data if you want a fresh session next time.

Important limitation

Even if you block cookies, Discord may still remember you through other storage methods, so the only reliable way to avoid persistent sign-in is to use a private window or remove all Discord site data after each session.

Safer setup

A practical setup is:

  1. Open a private window.
  2. Sign in.
  3. Use Discord.
  4. Close the window when done.

That keeps the login from sticking around on the device in most cases.

TL;DR

Use Discord in private/incognito mode, or clear Discord’s site data after each session. Blocking cookies alone is not always enough because Discord can also store login state in local storage.
