Introduction
If you’re trying to log into your Reddit account but find that the Reddit Authenticator is not working, you’re not alone. Many users face issues where the verification code doesn’t show up, appears invalid, or fails to grant access despite using the correct app. Since Reddit relies on two-factor authentication (2FA) to protect user accounts, any failure in the authenticator can be frustrating and may even prevent you from accessing your account entirely. In this article, we’ll break down the common causes behind the “Reddit authenticator not working” problem and guide you through quick, effective solutions to fix it and regain control of your Reddit account.

Why Is the Reddit Authenticator Not Working?
It could be due to incorrect time settings, outdated app version, sync issues, or problems with the linked account. Resyncing or reinstalling the app may help.
There are several reasons why your Reddit authenticator is not working, and identifying the root cause is the first step toward fixing it. Here are the most common issues users encounter:
1. Incorrect Time Sync
The most frequent reason why the Reddit authenticator isn’t working is that the time on your device is out of sync. Authenticator apps rely on time-based one-time passwords (TOTP), so even a small discrepancy in your device’s clock can result in invalid codes.
2. Wrong Authenticator App
If you’re using an unsupported or incorrect authenticator app, the generated codes may not work with Reddit. While Reddit works with most standard apps like Google Authenticator or Authenticator App ® 2FA, some third-party apps may not be fully compatible.
3. Code Entered Too Late
TOTP codes refresh every 30 seconds. If you enter the code too late or during the refresh period, Reddit may reject it as expired, making it seem like the Reddit authenticator is not working.
4. Account Migration or New Device
If you’ve recently switched phones or reinstalled your authenticator app without backing up or re-adding your Reddit account, the codes will no longer work. Reddit does not automatically transfer 2FA settings across devices.
5. Corrupted App Data or Cache
Sometimes, bugs in the app or corrupted cache files can interfere with the code generation process. This can cause the authenticator to fail even when everything seems correct.
6. No Backup Codes Available
If you lose access to your authenticator and don’t have backup codes, you’ll be locked out. This often leads users to search online for help with the “Reddit authenticator not working” issue.
How to Fix Reddit Authenticator Not Working?
Ensure correct time settings, update or reinstall the app, resync the authenticator, or use backup codes. If needed, contact Reddit support for account recovery.
Encountering the “Reddit authenticator not working” issue can be frustrating, especially when you’re locked out of your own account. Don’t panic — most problems with two-factor authentication (2FA) on Reddit are solvable with a few practical steps. Below are detailed instructions to help you fix the problem and regain access quickly.
1. Sync Your Phone’s Time Settings
Why this matters:
Reddit uses Time-based One-Time Passwords (TOTP) to verify your identity. If your device’s internal clock is even a few seconds off, the authenticator code may be invalid.
How to fix:
- On Android: Go to Settings → System → Date & Time → Turn ON “Use network-provided time” and “Use network-provided time zone.”
- On iPhone: Go to Settings → General → Date & Time → Enable “Set Automatically.”
After syncing, try generating a new code and logging in again.
2. Re-Add Reddit in the Authenticator App
Why this matters:
If your authenticator app was reinstalled or your phone was changed, old entries might not work anymore.
How to fix:
- Log into Reddit using your backup codes (if available).
- Go to User Settings → Safety & Privacy → Use Two-Factor Authentication.
- Disable 2FA, then enable it again to generate a new QR code or secret key.
- Scan the QR code using your new authenticator app.
3. Clear App Cache or Reinstall the Authenticator
Why this matters:
Corrupted cache files or bugs can prevent the authenticator from generating valid codes.
How to fix:
- On Android: Long press the app → App Info → Storage & Cache → Tap “Clear cache.”
- If that doesn’t work, uninstall and reinstall the authenticator app.
After reinstalling, re-add your Reddit account using the QR code or secret key.
4. Double-Check Code Validity and Timing
Why this matters:
TOTP codes refresh every 30 seconds. If you enter a code too close to expiration, Reddit may reject it.
Tips:
- Watch the countdown ring (if available) on your authenticator app.
- Enter the code quickly before it expires.
- Make sure you don’t mix up codes for multiple accounts (especially if using the same app for multiple logins)
5. Use Backup Codes Provided by Reddit
Why this matters:
Reddit provides backup codes when you first enable 2FA. These are your emergency keys if the Reddit authenticator is not working.
How to use:
- Go to the Reddit login page.
- Choose “Having trouble?” or “Use a backup code.”
- Enter one of the 8-digit backup codes you saved during the 2FA setup.
Pro Tip: Always save your backup codes in a secure password manager or offline file.
6. Contact Reddit Support as a Last Resort
Why this matters:
If you’ve lost access to both your authenticator app and your backup codes, Reddit support is your only recovery option.
How to contact:
- Visit support reddit
- Choose “Account Access Problem” or “2FA Issue.”
- Explain the situation and provide any identifying information Reddit requests (like account creation date, email, or associated subreddits).
7. Switch to Authenticator App ® 2FA for Better Reliability
If reddit continues to fail, try Authenticator App ® 2FA as a more reliable alternative:
- Download Authenticator App ® 2FA from the App Store at this link
- Set it up by scanning your account QR codes it offers seamless 2FA with encrypted iCloud sync, biometric authentication, and offline code generation, ensuring you’re never locked out.
