Account & Security

Two-Factor Authentication

Two-factor authentication (2FA) adds an extra layer of security to your Crypto Barter account. When enabled, you'll need both your password and a verification code from your phone to log in. This protects your account even if your password is compromised.

Why Use Two-Factor Authentication?

Enhanced Security:Even if someone obtains your password, they can't access your account without your phone.
Protect Transactions:Since Crypto Barter deals with cryptocurrency, 2FA helps protect your wallet addresses and transaction history.
Prevent Unauthorized Access:Get alerts when someone tries to log in to your account.
Industry Standard:2FA is recommended for all accounts involving financial transactions or cryptocurrency.

What You'll Need

Before setting up 2FA, you'll need an authenticator app on your smartphone. Popular options include:

Google Authenticator - Available on iOS and Android
Authy - Available on iOS, Android, and desktop
Microsoft Authenticator - Available on iOS and Android
1Password - Built-in authenticator if you use 1Password

Download one of these apps from your device's app store before proceeding.

Setting Up Two-Factor Authentication

Follow these steps to enable 2FA on your account:

Go to your Settings page
Find the "Security" or "Two-Factor Authentication" section
Click "Enable 2FA" to begin setup
Open your authenticator app on your phone
Scan the QR code displayed on screen (or enter the manual code)
Your authenticator app will now display a 6-digit code that changes every 30 seconds
Enter the current 6-digit code in the verification field
Click "Verify" to complete setup

Save Your Backup Codes

When you enable 2FA, you'll receive backup codes. These are critical for account recovery:

Save them securely: Store backup codes in a safe place separate from your phone
Each code works once: Use a backup code if you can't access your authenticator app
Don't share them: Treat backup codes like passwords - never share them
Generate new codes: If you use all backup codes, generate new ones from your settings

Logging In with 2FA Enabled

Once 2FA is enabled, here's what your login process looks like:

Enter your email/username and password as usual
You'll be prompted to enter a verification code
Open your authenticator app and find the code for Crypto Barter
Enter the 6-digit code (codes change every 30 seconds)
Click "Verify" to log in

Disabling Two-Factor Authentication

If you need to disable 2FA (not recommended):

Go to your Settings page
Navigate to the "Two-Factor Authentication" section
Click "Disable 2FA"
Enter a verification code from your authenticator app to confirm
Confirm that you want to disable 2FA

We strongly recommend keeping 2FA enabled for maximum account security.

Troubleshooting

Code not working:Make sure the time on your phone is accurate. Authenticator apps rely on precise timing.
Lost phone:Use one of your backup codes to log in, then set up 2FA with a new device.
No backup codes:Contact our support team for account recovery assistance.
Switching phones:Set up 2FA on your new phone before resetting your old one, or use backup codes.
