BtcTurk is a Turkish cryptocurrency exchange whose main platform is BtcTurk | Kripto. Two-step verification isn't optional there: every sign-in asks for a second code after your email or ID number and password. Out of the box, that code is a 6-digit SMS sent to the phone number on your account. BtcTurk recommends switching to an authenticator app after your first SMS sign-in, which removes the risk of someone copying your phone number to get in (BtcTurk). This guide makes that switch with Authenticator App - Novaz on iPhone. Any authenticator app works the same way.

How we checked this guide: the BtcTurk steps come from BtcTurk's own help centers, linked below. They turned away our automated reader, so on October 21, 2026 we read the pages as archived copies on web.archive.org, saved in April and July 2024. The articles show no date of their own. We haven't tested them on a BtcTurk account, so a label may differ slightly. The Novaz steps are checked against the app, version 1.0.5.

Before you start

  • Use the website. BtcTurk's help asks you to sign in on its website to scan the QR code, not in the mobile app (BtcTurk).
  • Turkish citizens and other users differ. BtcTurk's English help says Turkish citizens can switch between SMS and an authenticator app themselves (BtcTurk). Recovery is much harder for everyone else (below).

Switch from SMS to an authenticator app

BtcTurk | Kripto's help gives the place: Security > Security Center > Two-Step Verification, or in Turkish Güvenlik > Güvenlik Merkezi > İki Aşamalı Doğrulama (BtcTurk). The full walk-through only survives in BtcTurk's older help center, whose menu is one level shorter, so expect small differences (BtcTurk):

  1. Sign in to BtcTurk on the website and open the two-step verification page from the security menu.
  2. Choose Authenticator Kullan (use authenticator).
  3. Enter the SMS code BtcTurk sends you. The Authenticator Aktivasyonu screen opens with a QR code and a manual entry code, which the help shows highlighted in yellow.
  4. In Novaz, tap +, then Scan QR code, and point the camera at the code. If the page is on your iPhone, take a screenshot and use Choose a photo instead (how that works).
  5. To type the key, tap +, then Enter key manually, and fill in Service and the Setup key. BtcTurk's codes are 6 digits and change every 30 seconds, which matches what manual entry makes. See What is a 2FA setup key?
  6. Type the 6-digit code from Novaz into the field to the right of the QR code and choose KODU DOĞRULA (verify code).

From then on, BtcTurk asks for a code from your app every time you sign in.

Write down the key

BtcTurk's help doesn't mention backup or recovery codes. Its fallback is the manual entry code itself: the older article asks you to keep a record of it, so you can set the authenticator up again on another device or after losing access. Without a Novaz backup (iCloud backup or a backup file), the key exists only on that iPhone, so copy it somewhere safe away from the phone, such as a password manager, before you leave the setup screen. Anyone who has the key can make your codes, so treat it like a password.

If BtcTurk rejects your code

The error BtcTurk shows is Authenticator kodunu yanlış girdiniz. (you entered the authenticator code wrong). Its help blames the app's time being out of sync, and for iPhone it points to the same fix Novaz uses: Settings > General > Date & Time > Set Automatically (BtcTurk). Novaz also warns you when the clock is 15 seconds or more off. Other causes are in Authenticator code not working?

Moving to a new iPhone

If you turned on Novaz's iCloud backup or exported a backup file, restore it on the new iPhone and BtcTurk's codes keep working. Otherwise, if you saved the manual entry code, add it to Novaz on the new phone and check that the codes work before you wipe the old one. If you didn't, the documented route is to go back to SMS on the two-step verification page and then set up the authenticator again (BtcTurk). More in How to transfer your authenticator app to a new iPhone.

If you lose your authenticator

If you kept the key or the QR code, set the app up again with it. Otherwise, what happens depends on who you are (BtcTurk):

  • Turkish citizens ask BtcTurk support to switch them back to SMS and prove their identity. You then sign in with SMS and can turn the authenticator back on.
  • Other users with a Level 2 account contact support about manual recovery.
  • Other users with a Level 1 account have no way to recover the authenticator, according to BtcTurk. Saving the key matters most for you.

BtcTurk's newer Turkish article spells out the proof: deposit any amount of Turkish lira into your BtcTurk | Kripto account from a bank account in your own name, and send photos of the front and back of your Turkish ID card (a Turkish driver's license or passport also works), by email to destek@btcturk.com or through Live Support. It says the change takes about an hour, with confirmation by email and SMS, and that a Level 2 account drops to Level 1 afterwards (BtcTurk). The English lost-device article instead mentions a 24-hour wait before SMS sign-in works, so timings may vary.

If your phone was stolen, write to support@btcturk.com right away, change your BtcTurk password, and end other sessions under Security > Device Management. See also Lost the phone with your authenticator app?

Turning it off

BtcTurk's help doesn't describe turning two-step verification off, since every sign-in needs a second code. What it covers is switching back to SMS on the same page. Once you've done that, open the BtcTurk entry in Novaz and tap Remove account.
