Google Authenticator works fine on an iPhone right up until you add a second Apple device. Buy an iPad, get a Mac, or upgrade your phone, and the awkward truth shows: Google's app was never built for the Apple ecosystem. Your codes sync through a Google account instead of iCloud, there is no Mac app, and every login on your computer means reaching for your phone.
This guide looks at five alternatives specifically for people on iPhone, iPad, and Mac. If you want the platform-agnostic picture, read our full comparison of the best authenticator apps. This post is for people who live in Apple's world and want their 2FA setup to fit it.
Why iPhone users outgrow Google Authenticator
Let's be fair first: as a plain offline code generator, Google Authenticator does its job. The codes are standard TOTP, generated on your device, and the app is free. The problems show up at the edges:
- Sync is tied to a Google account, not iCloud. Since 2023 the app can back up your codes to your Google account. If you live on Apple hardware, that means the keys to every account you own depend on a Google login you may barely use. When the sync feature launched, security researchers also criticized it for not end-to-end encrypting the synced secrets.
- No Mac app. Your codes exist only on your phone. There is no way to see them on the machine where you actually type most of your logins.
- No integration with Apple's autofill. Codes stored in iCloud Keychain fill in automatically in Safari. Google Authenticator sits outside that system, so you switch apps and copy codes by hand.
- Migration is manual. Moving to a new iPhone means the "Transfer accounts" QR-code ritual between two phones, with no safety net if the old phone is lost or broken.
None of these are fatal. All of them are solved by apps built with Apple hardware in mind. Here are five worth considering.
The five best alternatives for Apple users
1. Authenticator by Vidus6: encrypted sync across iPhone, iPad, and Mac
This is our own app, so judge the entry accordingly, but it was built precisely for the gap this article describes. Authenticator by Vidus6 is free on iPhone, iPad, and Mac (Android too), generates standard TOTP codes entirely on-device, and works completely offline. Sync between your devices is end-to-end encrypted, and the encryption key never leaves your hardware. A new device only joins your vault after an existing trusted device approves it, so a stolen password alone can never expose your codes.
It imports a full Google Authenticator vault on-device using Google's own QR export, locks behind Face ID or Touch ID, needs no account to start, and comes with setup guides for over 2,000 services. The honest caveat: it is a newer app from a small studio, without the years of public track record that 2FAS or Microsoft can point to.
Best for: Apple users who want codes on every device without handing the keys to a cloud provider.
2. 2FAS: the free, open-source crowd favorite
2FAS is free, open source, and genuinely pleasant on iOS. On iPhone it can back up your tokens to your own iCloud, with an optional password to encrypt the backup, and its browser extension lets you approve logins from your phone instead of typing codes.
The trade-off for Apple users: there is no desktop app, so your Mac depends on the browser extension, and the codes themselves still live only on your phone. Within those limits, it is an excellent choice.
Best for: people who want open-source software and a simple iCloud backup without adopting a new sync service.
3. Ente Auth: open source with encrypted sync everywhere
Ente Auth, from the team behind the Ente photo service, is free, open source, and syncs with end-to-end encryption through an Ente account. It has apps for iOS, Android, desktop, and even the web, which makes it the most portable option on this list.
The trade-offs: sync requires creating an Ente account, and the desktop app is functional rather than Mac-native in feel. If you use Apple hardware today but are not sure you always will, this is a strong pick.
Best for: open-source purists who want encrypted sync on every platform, including outside Apple's ecosystem.
4. Microsoft Authenticator: the work-account choice
If your job runs on Microsoft 365, this app earns its place: push approvals for Microsoft sign-ins are faster than typing codes, and it stores standard TOTP entries for other services too.
As an Apple-ecosystem citizen, though, it is weak. Backups are tied to a personal Microsoft account, an iOS backup cannot be restored on Android (or the other way around), and there is no Mac app. Pick it because your workplace requires it, not for Apple fit.
Best for: people whose work identity lives in Microsoft's ecosystem.
5. Apple Passwords: the built-in option most people forget
Apple's own Passwords app (a dedicated app since iOS 18 and macOS Sequoia; the same feature lived in Settings since iOS 15) can store TOTP verification codes alongside your passwords. Codes sync through iCloud Keychain with end-to-end encryption and autofill automatically in Safari on iPhone, iPad, and Mac. It is free and already on your devices.
Two real trade-offs. First, it puts your password and your second factor in the same vault, so anyone who gets into your Passwords app has both. Second, there is no bulk import from Google Authenticator; you re-add each account by scanning its QR code again. It is also Apple-only, which matters the day you need a code on anything else.
Best for: people who want zero extra apps and accept keeping both factors in one place.

How to switch without locking yourself out
Good news: switching authenticator apps does not touch your online accounts at all. TOTP is an open standard, so once the secret moves to a new app, the codes it produces are identical.
- In Google Authenticator, use its transfer feature to export your accounts as QR codes.
- Import them into your new app. Our step-by-step import guide walks through the whole process. Apple Passwords is the exception: it has no bulk import, so re-add accounts there one at a time.
- Open both apps side by side and confirm every account produces matching codes before you delete anything.
- If you are doing this as part of a phone upgrade, read our guide to moving your authenticator to a new phone first; the order of operations matters.
FAQ
Is Google Authenticator actually insecure?
No. On-device TOTP generation is sound, and used fully offline with recovery codes stored safely, it is a reasonable tool. The criticisms are about its sync model and its poor fit with Apple devices, not the codes themselves. You are trading convenience, not baseline security, by staying.
Can Apple's Passwords app be my only 2FA app?
For many people, yes, and it is far better than SMS codes. Just understand the model: your password and second factor sit in one vault, and the whole setup assumes you stay on Apple hardware. If either bothers you, use a dedicated app.
Do websites care which authenticator app I use?
Not at all. The service only checks that your six-digit code matches its own calculation. Any standard TOTP app works with any service that supports authenticator apps.
Any app on this list beats Google Authenticator for life inside Apple's ecosystem; which one is right depends on whether you value open source, work integration, or zero extra apps most. If end-to-end encrypted sync across iPhone, iPad, and Mac is what you are after, download Authenticator by Vidus6 free and import your Google Authenticator vault in a couple of minutes.
