Ente Auth
The only mainstream 2FA app that is open source, end-to-end encrypted, and a real app on every platform you own — not just your phone.
For most people, Ente Auth is the authenticator app to switch to, and the reason comes down to a question almost nobody asks until they lose a phone: who can actually read your codes, and on what can you get to them. Ente Auth is fully open source, its clients and server have been externally audited (Cure53, Symbolic Software, Fallible), and the cloud backup that syncs your codes across devices is end-to-end encrypted — Ente itself cannot decrypt it, which is a meaningfully stronger guarantee than the two biggest names in the category currently offer. It is also genuinely cross-platform: native apps for iOS, Android, macOS, Windows and Linux, plus a web app, so a lost or replaced phone is a login-and-restore rather than a re-enrollment project with every site you use. Setup asks one thing most people skip: write down the recovery key it gives you at signup. Lose that key and lose every device at once, and even Ente cannot get your codes back for you — that is the direct cost of encryption nobody else can bypass, not a bug. If that trade feels like too much, the mainstream defaults are legitimate second choices. Google Authenticator now syncs automatically once you are signed into a Google account, which is convenient and free, but that sync is encrypted only in transit and at rest, not end-to-end, so Google can technically access the underlying codes — security researchers flagged this in 2023 and it is still the case. Microsoft Authenticator is the right call if your employer already requires it for a Microsoft or Entra work account. 2FAS is a strong free, open-source alternative to Ente Auth with one real gap: no native desktop app, mobile and a browser extension only.
What we like
- Fully open source, with the code and cryptography independently audited
- Cloud backup is end-to-end encrypted — Ente cannot read your codes even if compelled to
- Real native apps on iOS, Android, macOS, Windows and Linux, plus a web app
- Straightforward encrypted export if you ever want to move your codes elsewhere
- Free, with no account required to start using it locally
Trade-offs
- The recovery key is entirely on you — lose it and support cannot restore your codes
- Smaller company than Google or Microsoft, so long-term backing is a judgment call
- No browser autofill polish; you copy the code across rather than it filling in for you

If you care about something specific
Edge cases the winner doesn’t handle as well.
| App | Score | Best for | Why | Pricing |
|---|---|---|---|---|
| 2FAS | 9.0 | people who want a free, open-source app and don't need a native desktop client | Open source, free, and built around a genuinely simple setup: scan a code, done, with an optional encrypted backup to your own Google Drive or iCloud rather than a server 2FAS runs. It doesn't require an account to use locally. The one real gap next to Ente Auth is platform coverage — 2FAS ships mobile apps and a browser extension, but no native Windows, macOS or Linux app. | Free |
| Google Authenticator | 8.2 | people already living in a Google account who don't want to install anything else | Free, and since 2023 it backs codes up automatically the moment you sign into a Google account on the app, so a new phone just works. The trade-off is the backup itself: it is encrypted in transit and at rest but not end-to-end, meaning Google can technically access the underlying secrets it stores for you — a gap researchers pointed out in 2023 that has not changed. Fine for low-stakes accounts, not the pick if you want the provider locked out of your codes. | Free |
| Microsoft Authenticator | 8.1 | Microsoft, Entra work/school, and Xbox accounts | Free, with an encrypted backup tied to your Microsoft account and a passwordless push sign-in option for Microsoft accounts specifically. Many employers require it for work logins, which makes the decision for you. It is mobile-only — there is no desktop app — and it is less useful once you look past Microsoft's own ecosystem. | Free |
| Aegis Authenticator | 8.8 | Android users who want a fully local vault and no cloud at all | Open source, Android-only, and deliberately offline: codes live in an encrypted vault on your device with biometric unlock, and there is no automatic cloud sync to trust or distrust. Backup is a manual, encrypted export file you store yourself, and it will import from most other authenticator apps if you're switching. No iOS version, and moving to a new phone is on you, not the app. | Free |
| Apple Passwords | 8.5 | Apple-only households who want the code sitting next to the password it belongs to | Built into iOS 18, iPadOS 18 and macOS Sequoia and later, the Passwords app can generate and store verification codes alongside the login they belong to, then autofill both at sign-in. It syncs through iCloud Keychain like everything else on the device. It only exists inside Apple's ecosystem, and keeping the password and the second factor in the same vault is worth thinking through — see the FAQ below. | Free (built in) |
| Authy | 6.0 | people who already have it set up and haven't had a reason to move | Authy was the app that made multi-device 2FA backup mainstream, and if it's already working for you there's no fire drill required. But it has had a rough couple of years: Twilio shut down the desktop apps for Windows, macOS and Linux in 2024, making it mobile-only, and an unsecured API exposed phone numbers tied to a large number of Authy accounts the same year. Neither issue exposed the 2FA secrets themselves, but it's not where we'd point someone starting fresh in 2026. | Free |

Frequently asked questions
What is the best authenticator app for most people in 2026?
Ente Auth. It's open source, its backup is end-to-end encrypted so even Ente can't read your codes, and it has real native apps on every platform — phone, laptop, and browser — rather than mobile only. Google Authenticator and Microsoft Authenticator are perfectly reasonable if you're already deep in one of those ecosystems and want one less app; just know their cloud backups aren't end-to-end encrypted the way Ente Auth's or 2FAS's are.
Is Google Authenticator safe to use?
The codes themselves are generated the same way as in every other TOTP app — that part is a public, standardized algorithm and doesn't depend on which app you use. The weaker point is the cloud backup: it's encrypted in transit and at rest, but not end-to-end, so Google can technically access the synced secrets. It's still far better than having no second factor at all, or relying on text-message codes.
What happens if I lose my phone?
It depends entirely on the app's backup model, which is the single most important thing to check before you commit to one. Ente Auth and 2FAS both back up to the cloud, encrypted, so signing into a new device restores everything. Aegis has no automatic cloud backup by design, so you need an encrypted export file saved somewhere safe beforehand. Whichever app you use, also save the one-time backup codes most services hand you during 2FA setup — they work even if the app itself is gone.
Should I store 2FA codes in my password manager instead of a separate app?
1Password and Bitwarden can both generate and autofill TOTP codes, and it's genuinely convenient. Plenty of security people avoid it on principle, though: two-factor authentication is meant to combine two separate things, something you know and something you have, and putting both in the same vault turns them back into one thing if that vault is ever compromised. A dedicated authenticator app costs you a few extra taps and keeps the second factor actually separate.
Can I move my codes if I switch authenticator apps?
Usually, but not always cleanly. Aegis can import directly from most competitors, including Google Authenticator and Authy exports. Ente Auth and 2FAS support standard encrypted export/import. Google Authenticator's own transfer flow is built for moving between devices, not necessarily into a different app, so budget time to re-scan a few QR codes by hand if a service doesn't offer a clean export.
Is text-message (SMS) 2FA good enough?
It's better than no second factor, but it's the weakest widely available option — a SIM-swap attack can redirect your codes to someone else's phone without touching your device at all. Use an authenticator app wherever a site offers one, and treat SMS codes as a fallback rather than the plan.
What about hardware security keys instead of an app?
A hardware key (the kind that plugs in or taps over NFC) is a stronger category than any app on this list, because it's phishing-resistant in a way a six-digit code typed into the wrong site isn't. It costs money and can be physically lost, which is why most people start with a free authenticator app and add a hardware key later for their most important accounts — email and the password manager itself.
