IO Zoom 2FA: how to set up an authenticator app

IO Zoom is a hosting company that sells Linux and Windows VPS plans, managed cloud servers and dedicated servers. You manage those servers, invoices and support tickets from its client portal, and that portal login is what two-factor authentication (2FA) protects. IO Zoom offers it as an optional, free extra: after your username and password, the portal asks for a 6-digit code from an authenticator app on your phone (IO Zoom). The documentation doesn't mention text-message or email codes for this login.

IO Zoom's reason for it is blunt: someone who gets into your portal account could, as the company puts it, end up "potentially wiping out your server" (IO Zoom). This guide uses Authenticator App - Novaz on iPhone. Any authenticator app works the same way.

How we checked this guide: the IO Zoom steps come from IO Zoom's own announcement and support pages, linked below, which we read on October 21, 2026. We haven't tested them on an IO Zoom account, so a label may differ slightly. The Novaz steps are checked against the app, version 1.0.5.

A heads-up about the documentation

IO Zoom's whole explanation of 2FA is one announcement in its client portal, dated September 19, 2016. Its knowledgebase has no article on two-factor authentication: we searched it and browsed the account and billing section, and found nothing. The portal has been redesigned since 2016, so treat the steps below as a general map rather than an exact script. If a label doesn't match, look for a security section under your account menu.

Turn on 2FA with an authenticator app

The announcement describes this route (IO Zoom):

1. Sign in to the IO Zoom client portal with your username and password.
2. In the navigation bar, click your name on the right side.
3. Click Security Settings.
4. Choose the option to enable two-factor authentication.
5. IO Zoom shows a QR code. In Novaz, tap +, then Scan QR code, and point the camera at the screen. If the portal is open on the same iPhone, take a screenshot, tap +, then Choose a photo. See scanning a QR code on the same iPhone.
6. If you can't scan it, IO Zoom also lets you type the key by hand. The announcement calls it a "code" rather than a key, so look for a string of letters and numbers near the QR code. In Novaz, tap +, then Enter key manually, fill in Service (for example, IO Zoom), optionally Account, and paste the string as the Setup key. More in What is a 2FA setup key?
7. Type the current code from Novaz into the portal and finish the on-screen instructions.

IO Zoom says its codes have 6 digits and change every 30 seconds, which is the standard setting, so typing the key by hand works as well as scanning.

Backup codes

The announcement doesn't mention backup or recovery codes. If the setup screen offers any, save them somewhere other than your phone, such as a password manager or a printed copy. If you lose the phone without a Novaz backup, or your last backup file predates IO Zoom, those codes would be your spare way in. See 2FA backup codes.

If IO Zoom rejects your code

IO Zoom's pages give no troubleshooting advice for codes. Because the codes are time-based, a wrong clock on your iPhone is the usual cause. Turn on Settings > General > Date & Time > Set Automatically. Novaz warns you when the clock is 15 seconds or more off. Also make sure you're reading the IO Zoom entry in Novaz and typing the code before it changes. More causes are in Authenticator code not working?

Changing phones

IO Zoom doesn't describe how to move 2FA to a new phone. Do it while the old phone still works: turn 2FA off (start in Security Settings), then set it up again with the new phone. If you keep a Novaz iCloud backup or backup file, restore it on the new iPhone instead; without one, each account needs a fresh setup. See How to transfer your authenticator app to a new iPhone.

If you lose your authenticator

IO Zoom doesn't document a recovery process, what proof it asks for, or how long a reset takes. Your route is its support team. The support page lists a 24/7 helpdesk where you submit a ticket, with a typical reply in under 20 minutes, and a live chat. The live chat asks for a support PIN. IO Zoom's contact page also lists sales and billing email addresses, and its ticket form is reachable from the portal's contact link.

Since IO Zoom doesn't say what it needs, it makes sense to write from the email address on your account and mention details only the account holder would know, such as an invoice number. More in Lost the phone with your authenticator app?

Turning 2FA off

The announcement only covers turning 2FA on and doesn't say how to turn it off. Start in Security Settings, where you turned it on, or ask support.
