Do I need the Epic Games app or a phone for 2FA?

No. Epic offers its own authenticator in the Epic Games app, but also accepts any third-party authenticator app. The Authenticator extension generates the same standard codes in Chrome on your computer.

How do I get the Boogie Down emote?

Epic grants it for turning on two-factor authentication on your account. Turn on the authenticator app as described above, then sign in to Fortnite — Epic’s help pages list it as the 2FA reward.

Why do I need 2FA to gift in Fortnite?

Epic requires two-factor authentication to send gifts, to make it harder for someone with a stolen password to spend your V-Bucks on themselves. Once the authenticator is on, gifting becomes available.

What if I get locked out of my Epic account?

At the 2FA prompt choose “Try another way” and enter a backup code. Without backup codes, Epic’s account recovery process through support is the only way back — which is why saving them takes a minute and saves days.

Epic Games Authenticator App on PC — Turn On 2FA for Fortnite

An Epic account carries your whole game library, Fortnite skins and V-Bucks, and it is a frequent target of stolen-password attacks. Epic also ties some features to 2FA: its help pages say gifting in Fortnite requires two-factor authentication, and turning it on unlocks the Boogie Down emote.

Turn on two-factor authentication at Epic Games

Sign in at epicgames.com on your computer and open your “Account” page.
Choose the “Password & Security” tab.
Under “Two-Factor Authentication”, choose “Third-Party Authenticator App”.
Epic shows the setup for the app. Leave it on the screen and add it to the extension as described below.
Enter the code the extension shows into Epic’s field to finish — Epic confirms that 2FA is on.

Epic Games’s own instructions

Add Epic Games to Authenticator

Install 2FA Authenticator from the Chrome Web Store and pin it to the toolbar, so its icon is one click away.
Leave the Epic Games page with the QR code open. Click the Authenticator icon, then “Add Account” → “QR Code” → “Scan QR from screen”.
The account appears in the list with a six-digit code that changes every 30 seconds. Rename it if you like — the name is only for you.
Go back to Epic Games and type the current code into the confirmation field. If it is about to expire, wait for the next one.
Epic Games confirms that two-factor authentication is on. From now on it will ask for a code when you sign in — click the extension icon and copy it.

No QR code, or it will not scan? Look for the option to enter a key manually on Epic Games’s setup screen, copy the key, and add it in the extension with “Add Account” → “Manual” → “Secret Key”.

Get 2FA Authenticator for Chrome — free

Get your Epic Games backup codes

In “Password & Security”, the authenticator section has a “Get Backup Codes” button. Download or write the codes down and keep them away from this computer. If you ever lose the authenticator, the sign-in prompt has “Try another way”, where a backup code gets you in.

The code is not accepted?

Almost always the computer’s clock. The codes are calculated from the current time, so a clock that is a minute off produces codes that look right and are refused. Turn on automatic date and time in your system settings — step-by-step for Windows, macOS and Linux.

If the clock is right, check the key itself: paste it into the TOTP code generator and compare the code with the one in the extension. If they differ, the key was copied wrong — add the account again.
