Poloniex 2FA: how to set up an authenticator app
By the Novaz team · Updated October 29, 2026
Novaz steps checked against version 1.0.5

Poloniex is a cryptocurrency exchange, so your account can hold coins and move them out. Its two-factor authentication (2FA) adds a 6-digit code from an authenticator app to every sign-in. The most useful thing to know before you start: the "recovery key" Poloniex asks you to save isn't a separate backup code. It's the same 16-character key that sets up your authenticator app, so whoever has it can make your codes, and with it you can rebuild your 2FA on a new phone without contacting support (Poloniex, archived).
The steps below use Authenticator App - Novaz on iPhone. Any authenticator app works the same way.
How we checked this guide: Poloniex's help center now opens on poloniex.com and only shows its articles in a full web browser, so our automated reader couldn't load them. On October 21, 2026 we read the same articles as archived copies on web.archive.org, saved between September 2023 and February 2026, plus one live poloniex.com page. We haven't tested the steps on a Poloniex account, and labels may have changed since the copies were saved. The Novaz steps are checked against the app, version 1.0.5.
Which methods Poloniex offers
Poloniex's setup article says an authenticator app is the method, and that Poloniex doesn't use SMS for 2FA (Poloniex, archived). A newer live page on poloniex.com mentions both Google Authenticator and SMS under Settings > Security (Poloniex), so you may see an SMS option too. The authenticator app is the one Poloniex labels as recommended.
Turn on 2FA with an authenticator app
These steps follow the February 2026 copy of Poloniex's setup article and its screenshots (Poloniex, archived):
- Sign in to Poloniex on the website. Open the person icon at the top right and choose Security. (The live site calls this area Settings > Security.)
- Under Two-Factor Authentication (2FA), find Google Authenticator (Recommended) and click Enable. Any authenticator app works here, not only Google's.
- Poloniex shows a QR code and a 16-character key. In Novaz, tap +, then Scan QR code, and point the camera at the screen. If the QR code is on the same iPhone, take a screenshot and use Choose a photo instead. See scanning a QR code on the same iPhone.
- To type the key instead, tap +, then Enter key manually. Fill in Service, optionally Account, and paste the 16-character key as the Setup key. Poloniex's codes are 6 digits and change every 30 seconds, which matches what manual entry makes. See What is a 2FA setup key?
- Save the key and QR code somewhere safe before you go on (more below).
- Click Continue. A Security Verification box opens. Click Send Code, then enter the code Poloniex emails you.
- Enter the 6-digit code from Novaz and click Submit.
Keep the recovery key safe
Poloniex calls the 16-character key your recovery key and asks you to store it, together with the QR code, away from your phone (Poloniex, archived). Its pages don't mention any other backup codes.
Treat the key like a password, since anyone who finds it can produce your codes. A password manager or a printed copy in a safe place both work. Novaz can keep a copy too, through iCloud backup or a backup file, but this saved key works even without one.
Signing in afterwards
Once 2FA is on, Poloniex asks for your email address and password, then the current 6-digit code from your app, every time you sign in (Poloniex, archived).
If Poloniex rejects your code
Poloniex says the most common cause of an Incorrect Code error is a phone clock that's out of sync. On iPhone, its fix is the system setting, not anything in the authenticator app: Settings > General > Date & Time > Set Automatically. If it's already on, Poloniex suggests turning it off, waiting a few seconds, and turning it back on (Poloniex, archived). Novaz also warns you when the clock is 15 seconds or more off. More causes are in Authenticator code not working?
Changing phones
Poloniex's way is to add the account again on the new device from your saved recovery key or QR code: scan the saved QR code, or type the 16-character key (Poloniex, archived). If you back up Novaz, you can restore your accounts on the new iPhone instead; without a backup, this saved key is how you carry Poloniex over. See How to transfer your authenticator app to a new iPhone.
If you lose your authenticator
- Check the clock first, as above. Poloniex asks you to try that before contacting it (Poloniex, archived).
- Use your saved recovery key or QR code to set up Novaz again, as described under Changing phones.
- Without the key, open a support ticket and ask for a manual 2FA reset. Poloniex says more account detail gets a faster reset, and lists your recent deposits, trades, balances and account activity as helpful proof (Poloniex, archived). It warns this manual route "can be a lengthy process" but gives no timeframe (Poloniex, archived).

Turning 2FA off
The pages we read don't describe a switch to turn 2FA off yourself. The only documented route is the manual disabling through a support ticket, above.
