1) Quick checks before you reset 2FA
Browser issues
Some browser extensions or built-in blockers can prevent the Confirm button from working.
What to do:
Disable extensions like “Privacy Badger” or “I Don’t Care About Cookies”, or whitelist 3Commas.io
If you use Brave/Vivaldi (or similar), disable the built-in blocker for 3Commas.io
Try another browser or incognito/private mode
Time Sync Issues
If your 2FA app is on a phone:
Make sure your device time is synced automatically
Wait 10 to 30 seconds and try the next code
If you have a backup key
If you saved your 2FA backup key, install your 2FA app on another device and restore access.
Try using Authy instead of Google Authenticator to resolve syncing issues.
2. Start an emergency 2FA reset
If the steps above don’t work, you can reset 2FA. This requires a 5-day security waiting period.
Important: This process will disable your 2FA and all API keys connected to your exchanges for security reasons.
If You Are Logged In:
Click "Reset 2FA" to begin the process.
If You Are Locked Out:
Go to 3Commas Login and sign in.
On the 2FA page, click "Reset 2FA".
Check your email inbox (including spam/junk folders) for a confirmation code.
Once you enter the confirmation code, the 5-day waiting period starts.
Cancelling the Reset If You Regain Access
If you retrieve your 2FA backup key, log in and click “Cancel 2FA reset” in the confirmation email.
If no action is taken within 5 days, you will receive an email to confirm the final disconnection of 2FA and API keys.
Restore Your 3Commas Account After 2FA Reset
Once your 2FA reset is complete:
Log in and go to My Portfolio to reconnect your exchange accounts using new or existing API keys. Learn how to Update Connected Exchange Accounts.
Re-enable 2FA on the Settings page and store your backup key safely to prevent future lockouts.
