There are more than 50 alternatives to Authy for a variety of platforms, including iPhone, Android, iPad, Android Tablet and Mac apps. The best Authy alternative is Aegis Authenticator, which is both free and Open Source. Other great apps like Authy are Ente Auth, Proton Authenticator, Bitwarden Authenticator and andOTP.

Aegis Authenticator is a free, secure and open source app to manage your 2-step verification tokens for your online services.
Leaving a negative comment, not because Aegis is bad, but because it's still not a good competitor/alternative to everything Authy offers in terms of convenience (iOS app, and desktop/Windows app). With these two, Aegis would NO DOUBT be the best out there.
I chose it because it is private, open, simpler and versatile, in my opinion
Almost everyone thinks Aegis Authenticator is a great Authy alternative.
Aegis Authenticator is the most popular Android alternative to Authy.
Aegis Authenticator is the most popular Open Source & free alternative to Authy.
ente's Authenticator app helps you generate and store 2 step verification (2FA) tokens on your mobile devices.
Ente is miles better than most 2fa services atm and is completely open source and ad free
Not to mention it now has proper cross device support with its own desktop application, following authys own 2fa being discontinued
Really happy with this dev team imo the best 2fa service you can get atm
FOSS alternative to Authy with mobile and website token sync. Can also import/export keys. Only question is how long Ente will keep the service free.
Open source, desktop app & mobile app
Almost everyone thinks Ente Auth is a great Authy alternative.
Ente Auth is the most popular Web-based, Windows, Mac, iPhone, Linux, iPad & Android Tablet alternative to Authy.

Open-source and kept up to date!
Does not require an account. Open-source.
andOTP is fantastic, but it's not cross-platform like Authy.
Almost everyone thinks andOTP is a great Authy alternative.
Manage unique passwords and sensitive information with platform support for Mac, Windows, iOS, Android, and more. Features include auto-fill, security alerts, and cross-device synchronization.
It has a great built in 2FA system.
we're talking about 2FA apps, not password keeper
This alternative is disputed. 1Password is a legitimate Authy alternative, but it might have issues that some users think are important.
1Password is the most popular commercial alternative to Authy.
2FAS Authenticator is a simple and free application for Two Factor Authentication (2FA Authentication) which generates Time-based One-time Passwords (TOTP) and PUSH authentication*.
Simple & pretty interface, does the job with no bullshit. Option to cloud sync with Google account, not mandatory.
The multi-protocol security key offers the highest assurance, protecting devices with passwordless workflows and strong 2FA against phishing. It plugs into computers, tablets, and mobile devices, integrates PIN or biometric for identity verification, and reduces helpdesk costs.
Because it is the best Authenticator program out.
Almost everyone thinks YubiKey is a great Authy alternative.
Google Authenticator generates 2-Step Verification codes on your phone.
Authy is much better than Google Authenticator. Although local 2FA is more secure in general the security of the app itself is horrible. No cloud sync, only way to transfer 2FA is with the two devices next to each other and QR codes which is better than other solutions but much worse than Authy.
You really must not use Google Authenticator. The security on this app is awful. It requires no authentication to access beyond the phone login, which places is apart from every 2FA app on this list - and not in a good way. Moreover, it has no backup or restore function.
I have no idea why Google has left this in the dark ages, only that they have.
Some users think Google Authenticator is a great Authy alternative, some don't.
FreeOTP is a two-factor authentication application for systems utilizing one-time password protocols with support for Android (6 or later) and iOS (11 or later). Tokens can be added easily by scanning a QR-code or by manually entering in the token configuration.
A free open-source two factor authentication app for Android. It features encrypted backups, icons, categories and a high level of customisation. It also has a Wear OS companion app.
Authenticator generates two-factor authentication (2FA) codes in your browser. Use it to add an extra layer of security to your online accounts.
It is one of the best 2FA alternatives that can be used on a PC. Authy is doing this on mobile because it does not have mobile support. On the PC, the Authenticator is the best option. Cloud support, encrypted backup, and a clipboard have features such as copying. There is also an automatic filling option for 2FA fields, but in some cases, it fills information on other fields.
