Two-factor authentication (2FA) adds a second layer of security to your G2G account. Even if someone learns your password, they cannot sign in without the verification code from your device. This article explains how to enable, use, and recover 2FA.
Before you start
Buyers and sellers alike: 2FA is strongly recommended for any account that stores funds or completes trades. Sellers who hold a wallet balance should treat it as mandatory.
Make sure you have one of the following ready:
- An authenticator app (such as Google Authenticator or Authy).
- A phone number that can receive SMS codes.
- A safe place to store your backup recovery codes.
Enabling 2FA
- Open security settings: Go to Account Center > Security > Two-Factor Authentication.
- Choose a method: Select either an authenticator app or SMS verification.
- Scan or verify: Scan the QR code with your authenticator app, or enter the code sent to your phone.
- Save backup codes: Store the recovery codes shown on screen somewhere safe and offline.
Verification methods compared
| Method | Security | Works offline |
|---|---|---|
| Authenticator app | High | Yes |
| SMS code | Medium | No |
| Backup codes | High | Yes (one-time use) |
Important: If you lose access to your device, use a backup recovery code to sign in, then reconfigure 2FA immediately. If you have no backup codes, submit a support ticket for identity verification. G2G Support cannot bypass 2FA without verifying account ownership.
Need more help? You can submit a ticket through the Account Center at any time and our support team will assist you as soon as possible.
