Philips Hue 2FA: how to set up an authenticator app for your Hue account

A Hue account is what ties your Philips Hue lights, Bridges and Homes to you. It's what lets you control the lights while you're away, add more Bridges, and decide who else in the household gets access, including who can arm a Hue Secure system or watch its camera feeds (Philips Hue). That makes the account worth protecting, even though Hue doesn't make two-factor authentication (2FA) mandatory. It only recommends it (Philips Hue).
When you turn it on, Hue offers two ways to get the code: your phone number or an authenticator app (Philips Hue). This guide covers the app route with Authenticator App - Novaz on iPhone. Any authenticator app works the same way.
How we checked this guide: the Philips Hue steps come from Philips Hue's own support and account pages, linked below, which we read on October 21, 2026. We haven't tested them on a Hue account, so a label may differ slightly. The Novaz steps are checked against the app, version 1.0.5.
What Hue documents, and what it doesn't
Hue's help on 2FA is short: where the setting is, and that Hue then asks for a code when you sign in. It doesn't mention backup codes, a text key, code settings, changing phones or recovery, so check the setup screens for those yourself.
Turn on 2FA with an authenticator app
Hue's FAQ gives these steps (Philips Hue):
- Sign in to your Hue account.
- Go to Settings & preferences.
- In the Login & security section, select Enable under Two-factor authentication.
- Follow the on-screen instructions, and choose the authenticator app when Hue asks which method you want.
The FAQ doesn't say whether this happens in the Hue app or on the web. The same page sends you to www.account.philips-hue.com for other account tasks, such as signing up or resetting a password, so that site is a sensible place to look if you can't find the setting in the app.
When Hue shows a QR code, add it to Novaz:
- In Novaz, tap +, then Scan QR code, and point the camera at the code. If the code is on the iPhone you're holding, take a screenshot, tap +, then Choose a photo. See scanning a QR code on the same iPhone.
- If Hue gives you a key to type instead, tap +, then Enter key manually, and fill in Service (for example, Philips Hue), Account if you like, and the key as the Setup key. See What is a 2FA setup key?
- Type the code Novaz shows into Hue to finish.
Hue doesn't say whether its setup screen offers a key or what code settings it uses. Scanning the QR code is the safer choice, because the code carries those settings to the app. A key typed by hand always gives 6-digit codes that change every 30 seconds.
Phone number or app
An app makes its codes on your iPhone, so they can't be redirected by someone who takes over your phone number. The trade-off is that the keys live on your device, unless you back them up (in Novaz, with iCloud backup or a backup file). See Authenticator app vs SMS.
Signing in with Google or Apple
Hue lets you create an account with Google or Apple instead of an email and password, and you can't switch an account like that to a password later (Philips Hue). Hue's pages don't say whether its own 2FA setting applies to those accounts, so turn on 2FA for the Google or Apple account itself.
If Hue rejects your code
Hue's help has no advice on rejected codes. The usual cause is the iPhone's clock. Open Settings > General > Date & Time and turn on Set Automatically. Novaz also warns you when your clock is 15 seconds or more off. Other causes are in Authenticator code not working?
Before you change phones
With Novaz's iCloud backup or a backup file, you can restore your accounts on a new iPhone and keep your Hue codes. Without one, a new iPhone means adding Hue again. Hue doesn't describe how to swap the authenticator on its side. The safe order is to sign in on your old phone while it still works, look under Login & security for a way to turn off or change two-factor authentication, and set it up again with the new phone. Then remove the old entry in Novaz by opening it and tapping Remove account. See How to transfer your authenticator app to a new iPhone.
If you lose your authenticator
Hue's pages don't describe a recovery process for a lost authenticator, and they don't mention backup codes. If Hue gives you any recovery option while you set up 2FA, such as backup codes or a phone number as a second method, save it then: it's your way back in if the phone is gone and you have no Novaz backup.
If you're locked out, contact Philips Hue support. Its support FAQ page has a Contact us section with social channels, WhatsApp messaging and phone support (Philips Hue). Hue doesn't say what proof it asks for or how long it takes. Two things are worth knowing first: you can't change the email address on a Hue account, and a deleted account can't be recovered (Philips Hue). So don't delete the account and start over unless you're sure you have to.
