To make Roblox show your account code , turn on 2-step verification or Quick Login in your account security settings. Roblox shows recovery/backup codes after you enable 2-step verification, and it can show a one-time login code when you use Quick Login.

What to do

  1. Open Roblox and go to Settings.
  2. Tap Security.
  3. Turn on 2-Step Verification using email or an authenticator app.
  4. After it’s enabled, choose Generate or view the recovery codes Roblox gives you.
  5. Save those codes somewhere safe, because they’re meant for account recovery.

If you mean login code

  • On a new device, choose Log In with Another Device or Email Me a One-Time Code.
  • Roblox will display or send a code you enter to sign in.
  • One-time codes are temporary, and email codes depend on your verified email being set up correctly.

Important note

Roblox does not normally show a permanent “account code” on your profile; the code people usually mean is a recovery code , one-time login code , or Quick Login code.

TL;DR: Go to Settings > Security, enable 2-step verification , then generate the recovery codes Roblox provides.
