Reddit accounts are frequently targeted by automated credential-stuffing attacks — attackers take leaked username/password combinations from other sites and test them against Reddit. If you reuse passwords, your account is at risk. Two-factor authentication blocks these attacks entirely, requiring a second verification step that attackers cannot obtain from a data breach.
How to Enable 2FA on Reddit
- Go to reddit.com and sign in to your account.
- Click your username in the top right, then click User Settings.
- Click the Safety & Privacy tab.
- Under "Advanced Security", toggle on Two-Factor Authentication.
- Reddit will prompt you to re-enter your password for confirmation.
- A QR code appears. Open your authenticator app, add a new account, and scan the code. If you prefer, click Can't scan the QR code to get a plain text key.
- Enter the 6-digit code from your authenticator app to verify the setup.
- Reddit generates 10 backup codes. Download or copy these and store them securely. Each code can only be used once.
Reddit's 2FA Methods
Reddit supports authenticator apps (TOTP) as its primary 2FA method. Any standard TOTP app works — Google Authenticator, Authy, Microsoft Authenticator, 1Password, Bitwarden, and others are all compatible. Reddit does not support SMS verification or hardware security keys at the account level.
Using Backup Codes on Reddit
If you cannot access your authenticator app at sign-in, click Use a backup code on the 2FA verification screen. Enter any unused backup code to complete the sign-in. Each code works exactly once and is then marked as used. Once logged in, you can regenerate a new set of backup codes from Safety & Privacy settings — doing so invalidates all previous codes.
Why Reddit Accounts Get Compromised
Reddit accounts are valuable to attackers for several reasons: karma-boosted accounts can post links without restrictions, making them useful for spam and manipulation campaigns. Accounts with high karma and established history can be sold on dark web markets. Older accounts may also be used to bypass subreddit age or karma requirements for posting. Enabling 2FA significantly reduces your exposure to all of these risks.
Protecting Moderator and Content Creator Accounts
If you moderate a subreddit or run a community, the risk is higher. A compromised moderator account gives attackers the ability to ban users, remove posts, change subreddit settings, or post pinned content to your community. Reddit's admin team can in some cases restore a compromised mod account, but the process takes time and can cause real damage to your community in the interim. Enable 2FA on all moderator accounts and encourage co-moderators to do the same.
Reddit 2FA on Mobile
Reddit's mobile app supports 2FA at sign-in the same way the desktop site does. When you sign in on the app from a new device or after clearing app data, you will be prompted to enter your 2FA code. The authenticator app on your phone generates the code even without an internet connection.
Troubleshooting Reddit 2FA Issues
If your 6-digit code is rejected, start with your phone's clock. TOTP codes depend on accurate time, so enable automatic time and date on your device and try again. If you are entering a code that is about to expire, wait for the next 30-second refresh before submitting it. Reddit can also request 2FA when you sign in through a new client or the mobile app after a reinstall, so keep your authenticator app installed and backed up. If a code never seems to work and you cannot sign in, use a backup code from the sign-in screen — and once you are in, regenerate your backup codes from Safety & Privacy so you have a fresh set.
What Reddit 2FA Does Not Protect Against
Two-factor authentication stops attackers who have your password but not your second factor. It does not stop session hijacking: if you sign in on a compromised device or an untrusted third-party client, an attacker can use your active session without ever entering a code. It also does not protect you from phishing pages that ask for your username, password, and 2FA code at the same time — treat any page that requests a code outside of reddit.com's official login flow with suspicion. For moderators, Reddit adds extra checks on some sensitive actions, but the most effective habit is to review your active sessions under Safety & Privacy and sign out of anything you do not recognise.
What to Do If Your Reddit Account Is Compromised
If you still have access, change your password immediately, generate new backup codes, and sign out of all sessions. If you have been locked out, try the password reset flow with your verified email — Reddit may send a reset link that does not require 2FA. If the attacker changed your email address, use Reddit's support request form at reddit.com/account-support and provide as much detail as you can about your account history to prove ownership. Act quickly, because a compromised account with moderator privileges can cause damage to a community within minutes.
Reddit 2FA and Third-Party Apps
Third-party Reddit clients sign you in through Reddit's OAuth flow, and most of them will show the same 2FA prompt as the official app on their next login. If a client you use predates 2FA support or was abandoned by its developer, its login flow can fail or loop after you enable two-factor authentication. The reliable fix is to sign in once with the official app or the desktop site, then return to the third-party client and re-authorise it.
Authorisation tokens issued to apps are separate from your 2FA setup: revoking an app under Safety & Privacy does not affect your two-factor settings, and enabling 2FA does not automatically revoke apps you authorised earlier. If you suspect a device is compromised, revoke all app access and re-authorise only the clients you actually use.
Sessions that are already signed in stay active after you enable 2FA — the new requirement only applies to future logins. If you have logged in on shared computers, old phones, or third-party clients you no longer remember, sign out of those sessions yourself from Safety & Privacy once 2FA is on, otherwise they remain a door that does not need a code at all.
Extra Checks on Sensitive Moderator Actions
For certain moderator actions — editing a subreddit's rules, changing mod permissions, or configuring automod — Reddit may ask you to confirm your password or pass 2FA again even when you are already signed in. This is a deliberate defence against session hijacking: a short-lived session token cannot be used to take over a community if the sensitive action requires a fresh password-plus-code check.
If your subreddit relies on several moderators, give each person their own account with 2FA rather than sharing one login. A shared moderator account multiplies the risk: every former mod who still has the password — or the authenticator entry — keeps permanent access, and one leaked code compromises the whole team.
Make Reddit 2FA Survive a Lost Phone
Beyond the ten backup codes, you can scan the same QR code into a second device — an old phone, a tablet, or a computer with a TOTP app installed. Because both devices derive codes from the same secret, they produce identical six-digit codes, so a lost primary phone no longer means a locked-out account. Store the spare device somewhere safe and keep its app updated.
Remember that regenerating backup codes invalidates the old set, so reprint or re-export them after any change. Test the backup device once a month by signing in with its code, and if the spare is ever lost or sold, re-enroll 2FA entirely — a fresh secret leaves the lost device useless.
How to Spot a Reddit Phishing Page Before Entering a Code
Phishers build login pages that copy reddit.com's design and ask for your username, password, and 2FA code in one form. The code is the dangerous part: it is valid for 30 seconds, and the attacker submits it to the real reddit.com the moment you type it into the fake page — the login succeeds on their machine, not yours. The page URL is the only reliable tell, so check the address bar before entering anything and bookmark the real login page.
If you already entered a code into a suspicious page, act immediately: sign in from the official site, regenerate your backup codes, change the password, and revoke active sessions. Treat any message — including private messages on Reddit itself — that asks you to "verify" your account with a code as hostile, and never post screenshots of your authenticator entries in public threads where the 16-character secret would be visible.
