Stackfield 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
Stackfield is a collaboration platform for teams, made and hosted in Germany, where work happens in shared rooms. Its two-factor authentication (2FA) adds a short-lived code from an authenticator app to your password. That's the only second factor Stackfield's help describes, with no text-message option (Stackfield).
Before you start, know this: Stackfield treats its backup codes as your only way back in if your authenticator stops working. Your organization's admin may also make 2FA mandatory (more below). This guide uses Authenticator App - Novaz on iPhone, but any authenticator app works the same way.
How we checked this guide: the Stackfield steps come from Stackfield's own help pages, linked below, which we read on October 22, 2026. We haven't tested them on a Stackfield 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
Stackfield's help places the setting in your user account settings, in the browser or the desktop app (Stackfield):
- Open the settings of your user account and go to the Profile tab.
- Click the slider next to Two-Factor Authentification (that's how the help spells it) and enter your login password. Stackfield opens a page with your personal setup instructions.
- Stackfield shows a QR code on that page. In Novaz, tap +, then Scan QR code, and point the camera at it. If the code is on your iPhone's own screen, take a screenshot, tap +, then Choose a photo. See scanning a QR code on the same iPhone.
- Novaz shows a 6-digit code for Stackfield. Type it into the field on the Stackfield page and click Verify and Activate.
- Stackfield then shows your backup codes. Save them outside Stackfield before you leave the page.
The help article walks through scanning only. It doesn't mention a text key you could type instead. If Stackfield's page does offer one, you can add it in Novaz with + > Enter key manually, filling in Service and Setup key. See What is a 2FA setup key?
Your backup codes matter more than usual
Stackfield's help says the backup codes from setup are the only way to reach your account if you lose your phone or your codes stop working. It recommends saving or printing them more than once and never sending them unencrypted (Stackfield).
A Novaz backup (iCloud backup or a backup file) doesn't replace them: if the phone is gone and you have no backup, or it's older than your Stackfield entry, these codes are how you get in. Keep them on paper or in a password manager, not in a Stackfield room.
- To see them again: in your user profile settings, on the Profile tab, find the Login section and click Show your backup codes.
- To get new ones: Stackfield has no regenerate button. You turn 2FA off and set it up again, and Stackfield creates a fresh set. See 2FA backup codes.
Signing in
You sign in with your email address and password as before. A second screen then asks for the authentication code, and you type the current 6-digit code from Novaz (Stackfield). Stackfield's help doesn't say whether it asks for the code on every sign-in or remembers devices. It does recommend the desktop app so you don't have to sign in every time, and it emails you when an unfamiliar device signs in (Stackfield).
If Stackfield rejects your code
Stackfield's help puts this down to the phone's clock. Its first fix is to set your phone's time automatically: on iPhone, Settings > General > Date & Time > Set Automatically. Novaz also warns you when the clock is 15 seconds or more off.
If you still can't get a working code, Stackfield says to sign in with a backup code, then turn 2FA off and set it up again (Stackfield). Other causes are in Authenticator code not working?
New phone or lost phone
Stackfield handles both the same way (Stackfield):
- Get into Stackfield. If the browser or desktop app on your computer is still signed in, use that. If not, sign in with one of your backup codes, which works just like an app code.
- Turn 2FA off on the Profile tab.
- Turn it on again and scan the new QR code with the new phone.
For a new phone, you can skip these steps if you have a Novaz iCloud backup or backup file: restore your accounts on the new iPhone and the Stackfield codes stay the same. Without one, do the steps before you wipe the old phone. See How to transfer your authenticator app to a new iPhone.
Without a signed-in computer or backup codes, the help describes no other route. It only points to Stackfield support, at support@stackfield.com or through the contact page, for further problems. It doesn't say what proof support would ask for. See also Lost the phone with your authenticator app?
When your organization requires 2FA
On the Business plan, each user decides for themselves, and 2FA starts out off. From the Premium plan, an organization admin can make it mandatory: in the organization settings, open the Permissions tab and turn on the slider under Organization Access. After that, members can only reach the organization's content with 2FA turned on. Stackfield adds that its support has to enable this option first (Stackfield).
Turning 2FA off
Use the same slider on the Profile tab of your user account settings, in the browser or desktop app. Turning it off and on again is also how you switch apps (Stackfield). If your organization requires 2FA, keep in mind that Stackfield then only lets users with 2FA into the organization's content.
