How to enable 2FA

How to Enable Two-Factor Authentication (2FA) on Your CatFee Account

To further protect your CatFee account and funds, we strongly recommend enabling Two-Factor Authentication (2FA).

Once 2FA is enabled, you will need to enter a 6-digit verification code generated by your authenticator app when logging in or performing important account operations. This adds an extra layer of security to your account.

1. Download an Authenticator App

We recommend using one of the following authenticator apps:

Google Authenticator

Official download and setup guide: https://support.google.com/accounts/answer/1066447

Microsoft Authenticator

Official download page: https://support.microsoft.com/account-billing/download-microsoft-authenticator-351498fc-850a-45da-b7b6-27e523b8702a

We recommend downloading the app through the official website, Apple App Store, or Google Play. Avoid installing authenticator apps from unknown sources.

2. Open CatFee Security Settings

1. Log in to CatFee.io

2. Go to Account Settings

3. Open Security

4. Find Two-Factor Authentication (2FA)

5. Click Enable

3. Connect Your Authenticator App

After enabling 2FA, CatFee will display a QR Code and a corresponding 2FA Secret Key.

Open Google Authenticator or Microsoft Authenticator:

Tap “+” → Scan the QR Code displayed on CatFee

If you are unable to scan the QR code, you can manually enter the Secret Key shown on the page.

Once successfully added, CatFee will appear in your authenticator app and generate a 6-digit verification code that refreshes automatically.

4. Complete 2FA Verification

Return to CatFee and enter the current 6-digit verification code displayed in your authenticator app.

Click Confirm.

Once verification is successful, 2FA will be enabled on your CatFee account.

5. Back Up Your 2FA Secret Key

This step is very important.

When enabling 2FA, please securely save your Secret Key / Backup Key.

If you lose your phone, replace your device, or accidentally delete the authenticator app, you can use this key to restore access to your CatFee 2FA.

We recommend keeping your backup key in a secure offline location.

Never share your:

• CatFee account password

• 2FA verification code

• 2FA Secret Key / Backup Key

with anyone.

CatFee staff will never ask you for your password, 2FA verification code, or 2FA Secret Key.

6. What If You Lose Access to Your 2FA?

If you:

• Lose or replace your phone

• Accidentally delete your authenticator app

• Lose your 2FA backup key

• Cannot access your 2FA verification codes

please contact CatFee using the email address registered with your CatFee account and request a 2FA reset or recovery.

To protect your account and funds, we may require additional verification to confirm account ownership before resetting your 2FA.

Security Recommendation

For better account security, we recommend using:

2FA + a strong, unique password + securely stored backup key

Even if your account password is compromised, 2FA provides an additional layer of protection for your CatFee account and funds.
