To protect your wallet and account more securely, it is mandatory to enable Two-Factor Authentication (2FA).Please follow the steps below to set it up:

• 1. On OSL: Go to User icon → Settings → Security settings → Authentication (or click the "Setup 2FA")
• A QR code and secret key will be displayed.

• 2. On your phone: Download Google Authenticator from App Store / Play Store. (or any OTP-compatible app)
• On Google Authenticator: 

  • Tap “+” icon → select “Enter a setup key” and manually input the secret key from OSL.
  • Or select “Scan a QR code” and scan the QR code shown on OSL.
  • Once set up, a 6-digit OTP code will be generated (refreshes every 30 seconds).

• 3. On OSL: Enter the 6-digit OTP code from Google Authenticator, then click Confirm.

• Tip: Keep your app installed and do not delete it, as you will need it for future logins and transactions.

Optional: If you have a YubiKey physical device, you can use it to set up 2FA.

Steps:

1. Log in to your OSL account.
2. Go to the Settings tab → Security.
3. Under YubiKeys, click "ADD NEW".
4. On your computer, insert your YubiKey into a USB port and touch the YubiKey sensor pad. 

The system will automatically register your YubiKey and confirm activation.
