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. Enabling 2FA is one of the easiest and most effective ways to protect your assets.

For safety reasons, 2FA confirmation is mandatory for:

• Withdrawals;
• Managing the list of allowed and blocked IP addresses.

Apart from this, you can enable 2FA for:

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

What apps can be used for 2FA?

You can use any 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 Pass);
• Telegram Messenger.

Some 2FA methods can be used alongside others — for example, you can use Telegram alongside other authentication apps.

Important details about 2FA

• 2FA is required to confirm withdrawals, so you will need to enable 2FA the first time you withdraw (if you haven't already);
• 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 use 2FA verification as an alternative to biometrics: to sign in to your wallet and confirm transactions, but you must enable 2FA first;
• We highly recommend that you save your 2FA setup key. If you lose, change, or reset your current device/phone, you can use this setup key to re-enable 2FA on another device or import it to use with another authenticator on this device.
