If you lost your Binance authenticator key (the 16-digit backup key for Google Authenticator or Binance Authenticator), don't try to "reset your account". Instead, follow the official procedure to "reset 2FA (two-factor authentication)." This is not about changing accounts but re-binding a new authenticator. Your login access remains unaffected.
Step 1: Try to find the original key from memory
If you just can't find the dynamic code in the app but still have the backup key, use it to recover directly.
What to do: In your authenticator app, choose "Add account" or "Recover", and manually enter the 16-digit key you saved earlier.
How to do it: Open Google Authenticator or the Binance Authenticator app, tap the "+" sign, select "Enter setup key" (or a similar option), paste or type the combination of letters and numbers. If the key is correct, the app will generate a new 6-digit code.
Completion standard: The dynamic code for your Binance account appears again in the authenticator app and matches the 6-digit code required on the Binance login page.
Common failure reason: Many people only saved a screenshot of the QR code during binding but forgot to write down the key. The QR code becomes invalid after successful binding, so a screenshot of the QR code is useless; only the key is the recovery credential.
Step 2: If the key is completely lost, use the official "Reset Security Verification" process
If you can't retrieve the key, you don't need any third-party tools. Just use Binance's security verification reset channel.
What to do: When logging in, select "Security verification unavailable?" or "My authenticator is not working" to enter the reset process.
How to do it:
Visit the Binance official website or open the app, enter your account credentials.
When the system prompts for a verification code, click "Cancel", then select "My authenticator is not working".
The system will ask you to enter your password, then redirect to the "Reset Security Verification" page.
Check the 2FA device you lost access to (e.g., "Google Authenticator") and click "Confirm Reset".
Complete the identity verification steps required by the system; you may need to confirm via email/SMS verification codes.
Completion standard: The reset request is submitted successfully, and the page shows "Request submitted" or enters "Under review" status.
Risk reminder: After resetting 2FA, your account's withdrawals, C2C selling, internal transfers, and payment services will be restricted for 48 hours. This is a platform security measure, not a frozen account; it will be lifted automatically after 48 hours. During this period, you can still trade and deposit.
Step 3: Submit an appeal and video verification (if automatic reset fails)
If the system cannot verify your identity automatically, you need to use the manual appeal channel.
What to do: Submit an appeal request via the customer service ticket system and upload identity verification materials.
How to do it:
After the "Reset Security Verification" page operation fails, the system will guide you to submit an appeal.
You need to prepare a declaration video holding your identity document: Face the camera and clearly read a statement including "Today is [date], I am applying to reset my account's Google security verification. I confirm this is my own operation." Show the front of your ID card to the camera.
If you are not fluent in English, you can read the statement in Chinese, but you need to write the statement (with date and email) on a piece of paper and hold it together with your ID in front of the camera.
Submit the video and ID photo, then wait for review. Some users may also need to answer security questions (such as account registration date, registration IP, which can be found in the "Confirm your Registration" email).
Completion standard: Receive a notification from Binance customer service that the review is approved and confirm that 2FA has been reset.
Common failure reason: If the video recording has reflections, blurriness, or obstructions on the face or ID, or if the video has been edited, the review will fail. Ensure adequate lighting, clear text on the ID, and a continuous, unedited recording.
Verification method after the operation
After a successful reset, the system will prompt you to set up a new authenticator (re-scan a QR code or enter a new key). After binding the new authenticator, immediately write down the newly generated 16-digit key and store it offline in a safe place (e.g., a paper notebook), not just a screenshot.
Next steps
After binding the new authenticator, if you need to withdraw during the 48-hour restriction period, plan your funds in advance. The withdrawal function will automatically resume after 48 hours. It is recommended to enable SMS verification in the "Security Center" as an auxiliary recovery method. In case you encounter authenticator issues again, you can reset faster via SMS verification without going through the video appeal process again.
