Quidax 2FA: how to set up an authenticator app
By the Novaz team · Updated October 29, 2026
Novaz steps checked against version 1.0.5
On this page
Quidax is a crypto exchange, used mostly in Nigeria to buy, sell and withdraw crypto and naira. Its app and website now live at quidax.io. In the security settings, the authenticator option is labeled Google Authenticator, but the setup only gives you a key to paste into an app, so any authenticator app works (Quidax). This guide uses Authenticator App - Novaz on iPhone.
You can't really skip it if you trade. Quidax says 2FA is required to create a funds password, and the funds password is what you enter for actions such as trades and withdrawals (Quidax).
How we checked this guide: the Quidax steps come from Quidax's own help center, linked below, which we read on October 24, 2026. The help pages block automated visits, so we read the same articles through the help center's public article feed on support.quidax.io. We haven't tested the steps on a Quidax account, so a label may differ slightly. The Novaz steps are checked against the app, version 1.0.5.
Turn on 2FA with an authenticator app
Quidax's setup article describes the Quidax mobile app (Quidax):
- On the home page, tap the avatar (human-head) icon at the top left.
- Tap security centre.
- Google Authenticator shows Not linked. Tap it.
- Quidax shows a setup key. Tap copy. (The same screen has a download button if you still need an authenticator app.)
- In Novaz, tap +, then Enter key manually. Type Quidax as the Service, add your email in Account if you like, and paste the key into Setup key. See What is a 2FA setup key?
- Back in Quidax, enter your login password.
- Enter the 6-digit code Novaz now shows. Quidax offers a paste button for this field.
- Tap next. The security centre should now show Google Authenticator as enabled.
Quidax's current article mentions only the key, not a QR code, and doesn't say how long the key is or how often the codes change. Novaz makes 6-digit codes every 30 seconds from a typed key. If Novaz turns the key down as too short, or Quidax rejects correct-looking codes, check whether a QR code is shown anywhere on the setup screen and scan that instead.
A newer Quidax article calls the same place Profile > Security > Google Authenticator, so your app's labels may differ (Quidax).
Save the key, because there are no backup codes
Quidax's help center doesn't mention backup or recovery codes. Its recovery advice assumes you use Google Authenticator signed in to a Google account, so the codes come back on a new phone (Quidax). Novaz doesn't work that way: its keys stay on your iPhone unless you turn on iCloud backup (PRO) or export a backup file under Settings > Backup.
So before you finish step 5, keep a copy of the key Quidax gave you somewhere safe, such as a password manager. With it, you can add Quidax to another phone yourself. Without the key or an up-to-date Novaz backup, a lost phone means going through support (below).
When Quidax asks for a code
Quidax's help mentions the authenticator code at these points:
- signing in, after your password (Quidax);
- resetting your password, together with an email code. After a reset you can't withdraw coins for 48 hours (Quidax);
- crypto withdrawals, together with an SMS or email code (Quidax). Withdrawals to addresses on your Withdrawal Whitelist skip both checks (Quidax);
- creating or resetting a funds password (Quidax).
If Quidax rejects your code
Quidax names a wrong phone clock as the most common cause. On iPhone, open Settings > General > Date & Time and turn on Set Automatically (Quidax). Novaz also warns you when the clock is 15 seconds or more off. If the clock is fine and codes still fail, Quidax's next step is to have support turn 2FA off, as described below. More causes are in Authenticator code not working?
Changing phones
Quidax's own route is to switch Google Authenticator off under Profile > Security while you still have the old phone, then set it up again on the new one. Changing this setting pauses withdrawals for 24 hours, so withdraw first if you need to. Quidax also says to keep the old phone until you can sign in on the new one (Quidax).
With Novaz you have a third option: if you keep an iCloud backup or a backup file, restore it on the new iPhone and Quidax comes across with your other accounts. Otherwise, use Quidax's off-and-on route, or add the saved key to Novaz on the new phone. See How to transfer your authenticator app to a new iPhone.
If you lose your authenticator
If you saved the key, add it to Novaz again and sign in. If not, email support@quidax.com and ask for a 2FA reset. Quidax asks for (Quidax):
- a selfie holding your government-issued ID and a sheet of paper with "Quidax", today's date and the action you need (reset 2FA);
- a close photo of the ID on its own;
- the amount of your last crypto or naira deposit.
Send one email, not several. Quidax says repeat emails slow things down, and that it aims to reply within 30 minutes. It also warns that it never asks for your password or 2FA code and won't contact you first on WhatsApp or Telegram (Quidax). More in Lost the phone with your authenticator app?
