Guide to 2FA (Two-Factor Authentication)

Guide to 2FA (Two-Factor Authentication)

What is 2FA?

Two-Factor Authentication (2FA) adds an extra layer of security by requiring a six-digit code from an authenticator app, in addition to your email and password.

The code is time-sensitive and will expire shortly after it is generated.

Why is 2FA important?

Your email and password alone may be vulnerable to third-party attacks. By enabling 2FA, you add a second layer of protection, making it significantly harder for malicious actors to gain access to your account and assets.

Setting up 2FA on Coinhako

Before you begin, download an authenticator app such as Google Authenticator, Authy, or Duo on your mobile device.

On Web (Browser)

  1. Log in to your Coinhako account.

  2. Click the profile icon (top right), then select Account Information.

  3. On the Account Information page, go to 2-Factor Authentication.

  4. Toggle the button beside “2FA is disabled”.

  5. Open your authenticator app and add your Coinhako token by either:

    • Scanning the QR code, or

    • Copying and pasting the key into your authenticator app.

  6. Enter the six-digit verification code from your authenticator app, then click Next.

  7. 2FA is now enabled on your Coinhako account.

On Mobile (Coinhako App)

  1. Log in to the Coinhako app.

  2. Go to Hub > Profile & Settings > 2-Factor Authentication.

  3. Tap Setup 2FA.

  4. We recommend Google Authenticator, but you may also use Authy or Duo. Tap Next once your app is installed.

  5. Add your Coinhako token to the authenticator app by either:

    • Scanning the QR code, or

    • Copying and pasting the key into your authenticator app.

  6. Enter the six-digit verification code from your authenticator app, then tap Next.

  7. 2FA is now enabled on your Coinhako account.

Using 2FA on Coinhako

Once enabled, you will be prompted to enter a six-digit code each time you log in.

  1. Launch your authenticator app.

  2. Locate the six-digit code under Coinhako.

  3. Enter the code on Coinhako and click Authenticate.

Resetting Your 2FA

⚠️ Note: If you reset your email, password, or 2FA, withdrawals will be disabled for 24 hours.

You can disable 2FA in two ways:

1. Disable via Account Information

If you still have access to your authenticator app:

  • Log in to your Coinhako account.

  • Go to Profile icon > Account Information > 2-Factor Authentication.

  • Toggle off 2FA is enabled.

  • Enter the six-digit code from your authenticator app, then click Confirm.

2FA will now be disabled.

2. Disable with a Selfie (if you lost access to your app)

If you cannot access your authenticator app:

  • Log in to Coinhako and click I want to reset 2FA when prompted.

  • Prepare a selfie with:

    • Your ID document or passport (the same one used for account verification).

    • A handwritten note stating: “Coinhako Reset 2FA – [Submission date]”.

    • Your face clearly visible in the picture.

  • Upload the selfie under Choose File and select Request 2FA Reset.

  • Once verified, your 2FA will be disabled.

After that, you can re-enable 2FA by following the setup steps above.

Common Issues

I lost access to my authenticator app

If you change, reset, or lose your phone, you may lose access to your 2FA. Please reset your 2FA immediately using the steps above.

Where do I get my 2FA code?

All 2FA codes are generated by your authenticator app (Google Authenticator, Authy, Duo, etc.).

My 2FA code is invalid

This usually happens when your device’s time is not synced.

For Android devices

  • Open the Authenticator app

  • Tap the menu button (top right)

  • Go to Settings > Time correction for codes > Sync now

For iOS devices

  • Go to Settings > General > Date & Time

  • Enable Set Automatically (if already enabled, toggle it off, wait a few seconds, then turn it back on)

If the issue persists, repeat the steps or reset your 2FA.
