Error: Invalid 2FA code

Problem

I can't pass 2FA because I encounter the Invalid 2FA code error.

Possible reasons

This issue may occur due to time discrepancies between your device and Google Authenticator, or browser-related problems.

Solution

Here are several steps that can help you resolve most common 2FA issues.

1

Verify the 2FA code

Multiple accounts: If you manage multiple accounts, ensure you're using the correct 6-digit code associated with this specific account.

2

Synchronize device time settings

By ensuring your device's time is accurately synchronized, you can reduce the likelihood of encountering the error during the 2FA process.

For Windows:

1. Right-click the time display in the taskbar and select Adjust date/time.

2. Ensure that Set time automatically is enabled.

3. Click Sync now under Synchronize your clock.

For macOS:

1. Go to System preferences and select Date & Time.

2. Ensure that Set date and time automatically is checked.

3. If adjustments are needed, click the lock icon to make changes.

For Android:

1. Go to Settings.

2. Scroll to System and select Date & Time.

3. Ensure that Set time automatically and Set time zone automatically are enabled.

For iPhone:

1. Go to Settings.

2. Go to General and select Date & Time.

3. Enable the Set automatically toggle.

3

Clear browser cache and cookies

Sometimes, cached data can interfere with the 2FA process.

For Google Chrome:

1. Click the three dots in the upper-right corner and select Settings.

2. Go to Privacy and security and click Clear browsing data.

3. Choose Cookies and other site data and Cached images and files, then click Clear data.

For Mozilla Firefox:

1. Click the three lines in the upper-right corner and select Settings.

2. Go to Privacy & Security and scroll to Cookies and site data.

3. Click Clear data, select both options, and confirm.

4

Use Incognito/Private browsing mode

This mode disables extensions and uses default settings, which can help identify browser-related issues.

For Google Chrome:

• Press Ctrl + Shift + N to open an incognito window.

For Mozilla Firefox:

• Press Ctrl + Shift + P to open a private browsing window.

5

Check the Internet connection

A stable internet connection is important for 2FA processes.

1. Ensure you're connected to a reliable network.

2. Avoid using VPNs or proxies during the authentication process, as they can cause synchronization issues.

6

Remove and re-add the account in Google Authenticator

If none of the above worked, try deleting and re-adding your account in Google Authenticator.

1. If you can access your profile settings in B2BINPAY, disable the 2FA temporarily.

2. Open Google Authenticator and delete the existing 2FA entry for your account.

3. Re-enable 2FA on your account and scan the new QR code to add it back to Google Authenticator.

4. Test logging in with the new code.

If the problem persists, contact the Support Team for further assistance.
