If you are having trouble completing Two-Factor Authentication (2FA) when signing in to your GunBroker account, there are several common issues that may prevent you from receiving or entering your verification code. Review the troubleshooting information below to identify the issue you are experiencing and the steps you can take to resolve it.
Why am I not receiving my verification code?
Verification codes are sent to the phone number(s) on your account.
- Cell phones receive the code by SMS text message.
- Landlines receive the code by automated voice call.
If you are not receiving your code, review the questions below.
Is the phone number on my account correct?
An incorrect or outdated phone number is the most common reason codes are not received. If your number has changed, contact us to update it at Customer Support. Please provide the new number when contacting support.
Is your phone blocking the message?
Some devices or carriers may block automated text messages or calls as spam. Check your spam or blocked message settings and try requesting a new code.
Does your phone use call screening or an automated answering service?
Features such as call screening, spam call filtering, or automated answering services may prevent you from receiving voice verification calls.
- You may want to add our number to your Contact List to ensure it will not get caught in your Spam Filtering.
- If your phone is a landline and uses an answering service, you may provide an alternate number for the code to be sent to.
Is your mobile device able to receive text messages?
If you're using a cell phone, confirm that:
- You have cellular service.
- SMS messaging is working.
- Your inbox is not full.
Why do automated verification calls show my landline as busy when other calls work?
If you're able to receive normal phone calls but automated verification calls report your landline as busy, the issue is typically related to your phone service or carrier—not the verification system.
Common causes include:
- Older landline equipment that does not respond well to automated dialing systems.
- Line voltage or wiring issues that make the line appear busy.
- Carrier routing or signaling problems between your telephone provider and the automated calling service.
- Call-blocking, privacy, or Caller ID features that automatically reject certain automated calls.
If this issue persists, we recommend contacting your telephone service provider to have your line tested and to verify that it can receive automated calls. You may also consider updating your account with a mobile phone number if one is available.
Have you requested multiple codes?
If you've requested several codes in a short period, use the most recent code. Earlier codes become invalid.
Did the code expire?
Verification codes expire after a short time. If your code has expired, request a new one.
Password Managers or Autofill Interfering with the 2FA Code Field
If you receive your 2FA code but have difficulty entering it, a password manager, password vault, or browser autofill feature may be interfering with the verification code field.
Some password managers and browsers may incorrectly recognize the 2FA field as a password or other saved-information field. This may cause saved information to be automatically entered, replace the code you type, display an autofill prompt over the field, or prevent the code from being entered correctly.
Try the following:
- Type the 2FA code manually instead of using autofill.
- Dismiss any password or autofill suggestion that appears over the 2FA code field.
- Temporarily disable your password manager or browser autofill and try signing in again.
- If you use both a password manager and your browser's built-in password-saving feature, temporarily disable one to determine whether they are conflicting.
- Try signing in using a private/incognito browser window. Depending on your browser settings, this may prevent extensions from interfering with the 2FA field.
- Try a different browser or device.
Important: If your password manager asks you to save or update your GunBroker password after entering a 2FA verification code, do not save the verification code as your password. The 2FA code is temporary and does not replace your GunBroker account password.
If you are able to enter the 2FA code after disabling or bypassing autofill, review the settings for your password manager or browser. Instructions vary depending on the program you use.
Important notes for the best 2FA experience:
- Please be patient as authentication text or call may take up to 5 minutes to appear/be received
- Clicking "Request another code" generates a new code and invalidates the previously sent code which may further delay authentication until the new code is received
- Each code is valid for 20 minutes
- Accounts will be locked-out after 3 consecutive unsuccessful attempts
