Coinut is a Singapore platform for moving money between regular currencies, stablecoins and crypto (Coinut). Its two-factor authentication (2FA) works with an authenticator app, and Coinut's help names Google Authenticator and Authy as examples (Coinut). The help pages don't say 2FA is required. They don't describe backup codes either, and the self-service reset relies on the phone number on your account, so that number matters more here than on most sites. This guide uses Authenticator App - Novaz on iPhone. Any authenticator app works the same way.

How we checked this guide: the Coinut steps come from Coinut's own help center and website, linked below, which we read on October 24, 2026. The help center's web pages showed a bot check to our plain requests, so we read the same articles through the help center's public article feed on help.coinut.com and compared them with archived copies on web.archive.org. We haven't tested the steps on a Coinut account, so a label may differ slightly. The Novaz steps are checked against the app, version 1.0.5.

Before you start: check your phone number

Coinut asks new users to add a phone number right after they verify their account (Coinut). Coinut's reset page for a lost authenticator sends a text-message code to a phone number (more on that below). If the number on your account is old, update it before you rely on 2FA. Coinut's help doesn't describe how to change the number.

Turn on 2FA with an authenticator app

Coinut's setup article is short (Coinut):

  1. Sign in to Coinut on the web.
  2. Open your account Settings and find the Two-Factor Authentication section, which shows a barcode (a QR code).
  3. In Novaz, tap +, then Scan QR code, and point the camera at the code. If you're on the same iPhone, take a screenshot, tap +, then Choose a photo. See scanning a QR code on the same iPhone.
  4. Type the one-time passcode (OTP) from Novaz into Coinut to finish.

The article adds one warning for step 4: "make sure the domain is coinut.com." Check the address bar before you type a code, since a look-alike site could pass your code on.

Coinut's help doesn't mention a text key you can type instead of scanning. If you don't see one, scan the barcode. If Coinut does show one, in Novaz tap +, then Enter key manually, and type it as the Setup key (see What is a 2FA setup key?).

When Coinut asks for a code

Once 2FA is on, Coinut asks for a code from your app each time you sign in (Coinut). Withdrawals ask too: the crypto withdrawal form wants the 6-digit code from your app before you select Submit, and Coinut then emails you a link to confirm or cancel the withdrawal (Coinut).

Coinut also lets you sign up with a Google or Facebook account (Coinut). Its help doesn't say whether the Coinut code is still asked for when you sign in that way.

If Coinut rejects your code

Coinut's troubleshooting article blames the clock in most cases. It says your phone and your computer should both have the right time, and that a phone with automatic date and time turned off is the usual culprit (Coinut). The article is written for Google Authenticator, but the advice is the same for Novaz.

On iPhone, open Settings > General > Date & Time and turn on Set Automatically. Novaz warns you when the iPhone's clock is 15 seconds or more off. Also check your computer's clock. For other causes, see Authenticator code not working?

No backup codes

Coinut's help pages don't mention backup or recovery codes. Plan as if there are none: besides the code in Novaz, Coinut only documents the reset page and support email below. Unless you've turned on iCloud backup or kept a backup file, Novaz's keys exist only on that iPhone, and a lost or wiped phone means using the reset.

If you lose your authenticator

Coinut gives two routes (Coinut):

  • Reset it yourself at coinut.com/revoke-otp. The page, titled Revoke one-time password, asks for your Username or Email address, your Phone Number, an SMS Verification Code (sent when you select Get SMS Code) and a Captcha (Coinut).
  • Email support at support@coinut.com if you've lost your phone or can't use your 2FA. Send your Coinut username, your email address and your phone number.

Coinut's help doesn't say how long support takes. A separate article on frozen accounts says Coinut may ask for more information or documents to verify you (Coinut), so have details such as your last sign-in date ready. More in Lost the phone with your authenticator app?

Changing phones

Coinut doesn't describe moving 2FA to a new phone, and its help has no setting for turning 2FA off. In Novaz, iCloud backup or a backup file restores your accounts on the new iPhone, so the codes keep working. Without one, the documented way to clear the old setup is the Revoke one-time password page above, after which you can scan a new barcode in Settings. Keep the old phone until Coinut accepts a code from the new one. See How to transfer your authenticator app to a new iPhone.
