What is two-factor authentication (2FA) and how is it used in NC Wallet?

Two-factor authentication (2FA) is an additional layer of NC Wallet security. For safety reasons, 2FA confirmation is mandatory for

• Withdrawals;
• Managing the Allowed and Blocked IP List.

Apart from this, you can enable 2FA for

• Signing in to your wallet;
• Confirming exchanges;
• Setting limits for withdrawal and exchange.

Two-factor authenticators:

You can use different types of authenticators depending on your device and preferences:

• Google Authenticator;
• Apple Passwords;
• Other two-factor authentication applications installed on your device (for example, Microsoft Authenticator, Samsung Authenticator);
• Telegram Messenger.

Also, it’s possible to enable 2FA using different authenticators and use them in parallel.

Important notes on 2FA:

• You need to activate two-factor authentication during your first withdrawal if you have not already done so;
• For security reasons, we don't recommend synchronising your Google Authenticator with the Google account that you use to sign in to your NC Wallet;
• You can also switch to biometrics to sign in and confirm transactions, but you need to enable 2FA first;
• We highly recommend that you back up your 2FA security key. If you lose, change, or reset your current device/phone, you can use this security key to re-enable 2FA on another device; or import it to use with another authenticator on this device.
