Koofr is a European cloud storage service for your files, on the web, desktop and phone. Two-factor authentication (2FA) on Koofr is optional, and it has one rule you should know before you switch it on. If you lose your second factor and your recovery codes, Koofr's support team can't let you back in, and the account is gone for good (Koofr).

For the second factor, Koofr accepts a time-based code from an authenticator app or a passkey, and you can add more than one (Koofr). This guide uses Authenticator App - Novaz on iPhone, but any authenticator app works the same way.

How we checked this guide: the Koofr steps come from Koofr's own help pages, linked below, which we read on October 22, 2026. We haven't tested them on a Koofr 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

Koofr's help describes these steps in the Koofr web app (Koofr):

  1. Open the Koofr web app and click Preferences.
  2. In the menu on the left, choose 2-Factor Authentication.
  3. Click Add Authentication app.
  4. Type your password in the Password field and click Continue.
  5. Give the app a name in Koofr, then scan the barcode Koofr shows. In Novaz, tap +, then Scan QR code, and point the camera at it. If you're doing this on the same iPhone, take a screenshot, tap +, then Choose a photo. See scanning a QR code on the same iPhone.
  6. Type the 6-digit code from Novaz and click Continue.
  7. Save the recovery codes Koofr shows, then click Add.

Koofr's help only mentions scanning the barcode and doesn't say whether a text key is offered, so scan it if you can. If you do find a key, see What is a 2FA setup key?

Add a second factor as a spare

Koofr lets you keep several second factors on one account, for example Novaz plus a passkey on your computer or a security key (Koofr). Koofr suggests this as a way to avoid a lockout if you lose your phone and your recovery codes (Koofr). Unless you've made a Novaz backup (iCloud backup or a backup file), its keys exist only on your iPhone, so a second factor is worth the extra minute.

Your recovery codes

Koofr gives you recovery codes when you turn on 2FA. Its help mentions 10 of them (Koofr). Each one works once, and Koofr asks you to keep them for emergencies rather than use them as your everyday second factor (Koofr).

You can see them again later: in the web app, open Preferences, choose 2-Factor Authentication, then click View Two-factor recovery codes (Koofr). Keep a copy away from your phone, on paper or in a password manager. More in 2FA backup codes.

Signing in

Once 2FA is on, Koofr asks for your password and then for your second factor when you sign in (Koofr). Its help doesn't describe trusted devices or how often the code is asked for after that.

If Koofr rejects your code

Koofr's help names two causes (Koofr):

  • The phone's clock is wrong. On iPhone, go to Settings > General > Date & Time and turn on Set Automatically. Novaz warns you when the clock is 15 seconds or more off.
  • You're using an old entry. If you turned 2FA off and on again, the old Koofr entry in your app no longer works. Koofr's fix is to turn 2FA off with a recovery code, delete every old Koofr entry from your authenticator app, and set 2FA up again. In Novaz, open the old entry and tap Remove account.

Changing phones

Koofr's help doesn't describe a phone move as such. Because it allows several second factors and lets you remove any one of them, you can add the new phone before dropping the old one (Koofr, Koofr). Set up Novaz on the new iPhone with Add Authentication app, then remove the old app's entry from Koofr. With a Novaz iCloud backup or backup file, you can restore your accounts on the new iPhone instead. Without one, do this while you still have the old phone. See How to transfer your authenticator app to a new iPhone.

If you lose your authenticator

What you can do depends on what else you set up (Koofr):

  • You have another second factor, such as a passkey: sign in with it and remove the lost app from your account.
  • The app was your only factor: sign in with your password, and on the 2FA screen click the link No longer have access to your second factor? Click here to use a recovery code. Then type one of your codes (Koofr).
  • No app and no recovery codes: Koofr says its support team can't restore access, for security reasons, and you lose the account permanently (Koofr).

Removing the authenticator app

In the web app, open Preferences from the account menu and choose 2-Factor Authentication. Your connected apps and passkeys are listed there. Click the (-) button next to the one to remove, type your password, click Continue, and then confirm with a code or a passkey (Koofr). Koofr's help doesn't say whether removing your last second factor turns 2FA off completely.
