The scariest moment with two-factor authentication is not a hacker. It is a cracked screen, a new phone, and the slow realization that all your login codes lived only on the device that just died.
Picking an authenticator app with backup built in is the difference between a five-minute phone upgrade and a weekend locked out of your accounts. The codes themselves are easy; the part that matters is what happens when the phone is gone. These nine apps all offer some form of multi-device sync or cloud backup, and here we compare them on how you actually recover, rather than how they generate a code.
Quick Take
- The feature that matters most is recovery: how you get your codes back when your phone is lost or replaced.
- Prefer apps with end-to-end encrypted backups, so the provider cannot read your codes even if their servers are breached.
- Whatever app you pick, also save each account’s own one-time recovery codes offline as a final safety net.

How We Chose These
We looked for apps that keep your codes recoverable when a phone is lost, through multi-device sync or a restorable backup, rather than trapping them on one device. We gave extra weight to end-to-end encryption, since a backup the provider can read is a backup an attacker might reach. And we spread the picks across free and paid, open-source and mainstream, so there is a fit whether you live in one company’s ecosystem or want full control of your data.
1. Ente Auth
A strong all-round choice: Ente Auth is free, open-source, and stores end-to-end encrypted backups, so your codes sync across iOS, Android, desktop, and the web while staying unreadable to Ente itself. Recovery on a new phone is a simple sign-in. The main caveat is that it is newer than the big names, so it has a smaller track record, though its open code and encryption model are reassuring.
2. Authy
Authy has long been the go-to for painless recovery, with multi-device sync and opt-in encrypted backups that make restoring on a new phone straightforward. It remains capable and popular. Two honest caveats, though: Authy suffered a 2024 breach that exposed millions of phone numbers, and it has discontinued its desktop apps, so it is now a mobile-first option.
3. 2FAS
Open-source and refreshingly simple, 2FAS needs no account to use and offers optional encrypted backup to your own iCloud or Google Drive, plus a handy browser extension. It is a privacy-minded pick that keeps you in control. The trade-off is that the backup is something you must switch on and manage yourself, so recovery is only as good as the backup you remembered to set up.
4. Microsoft Authenticator
For anyone living in Microsoft accounts, Microsoft Authenticator offers cloud backup, passwordless sign-in, and smooth restore tied to your Microsoft account. It is polished and widely supported. The rough edge is that restoring across platforms, iPhone to Android or back, can be fiddly, and the backup leans on a Microsoft account you must keep accessible.
5. Google Authenticator
Once famous for stranding people on a lost phone, Google Authenticator now syncs your codes to your Google account, so a new device just signs in. It works with Google and non-Google accounts alike and is everywhere. The catch worth knowing is that its cloud sync is not end-to-end encrypted by default, meaning Google can technically access the synced data, which matters if that is a concern for you.
6. Bitwarden
Bitwarden folds one-time codes into its open-source password manager, so your passwords and authenticator codes sync together in one encrypted vault across every device. Recovery comes with your Bitwarden login. The thing to weigh is that keeping passwords and codes in the same place is convenient but concentrates risk, so a strong master password and its own two-factor protection are essential.
7. 1Password
1Password does the same trick with more polish, storing your codes alongside your logins and syncing them everywhere, with a well-designed recovery kit for getting back in. It is a favorite for households and teams. The downsides are that it is a paid subscription and, as with any manager, your codes and passwords share one vault, so that account becomes the thing you must guard hardest.
8. Proton Authenticator
From the maker of Proton Mail, the Proton Authenticator offers free, end-to-end encrypted sync across platforms with the privacy focus Proton is known for. Recovery is a simple encrypted restore. Being newer, it has a shorter history than the incumbents, and it makes the most sense if you already use or trust the wider Proton ecosystem.
9. Apple Passwords
If you are all-in on Apple, the built-in Passwords app on iPhone, iPad, and Mac generates verification codes and syncs them through iCloud Keychain, so a new Apple device restores them automatically. There is nothing extra to install. The limit is the ecosystem: it shines on Apple hardware and is awkward or limited on Windows and Android, so it fits best if your devices are all Apple.
The Takeaways
- Judge an authenticator app by its recovery path rather than its codes, since that is what saves you on a new phone.
- Ente Auth and Proton Authenticator lead on free, end-to-end encrypted backup; Authy is easy but carries a 2024 breach.
- Password managers like Bitwarden and 1Password sync codes with logins, trading one vault’s convenience for concentrated risk.
- Whichever you choose, store each account’s own recovery codes offline as a final backstop.
Frequently Asked Questions
What is the easiest authenticator app to recover on a new phone?
Apps with cloud sync make it easiest, since a new phone just signs in. Ente Auth, Proton Authenticator, and Authy all restore quickly, and password managers like Bitwarden or 1Password bring your codes back with your login. The key is choosing one with backup turned on before you lose the old device.
Are cloud-backed authenticator apps safe?
They can be, and the deciding factor is encryption. An app with end-to-end encrypted backup, such as Ente or Proton, keeps your codes unreadable to the provider, so a server breach does not expose them. Backups that are not end-to-end encrypted are more convenient but place more trust in the company holding them.
Should I use an authenticator app or a password manager for 2FA codes?
Both work. A dedicated authenticator keeps codes separate from passwords, which some prefer for security. A password manager like 1Password or Bitwarden is more convenient because codes and logins sync together. If you use a manager, protect it with a strong master password and its own second factor, since it holds everything.
What happens if I lose my phone with no backup?
Without a backup or synced app, you fall back on each account’s one-time recovery codes, which is why saving those offline matters. If you have none, you face each service’s account recovery process, which can be slow. Set up backup now, and store recovery codes somewhere safe, to avoid that situation entirely.
Is Aegis Authenticator a good option?
Aegis is a well-regarded open-source app for Android with strong local encryption, favored by privacy-focused users. Its backups are encrypted files you export and store yourself rather than automatic cloud sync, so recovery depends on keeping those exports safe. It is excellent for control, less so if you want hands-off restore.
Back Up the Codes, and the Recovery Codes Too
The best authenticator app is the one you can walk away from when your phone breaks. Pick one with a recovery path you trust, lean toward end-to-end encrypted backup like Ente or Proton, and turn that backup on today rather than after something goes wrong. Then save each account’s own recovery codes offline, so even a total loss has a way back. For more on the tools that keep your accounts safe, browse Wayodd’s Software section.
