Authy is described as 'Manage and secure two-factor authentication easily across Gmail, Dropbox, and more. Sync devices, secure backups, and enjoy offline access' and is a very popular Authenticator in the security & privacy category. 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 1Password.
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.
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
Generates and stores two-factor authentication tokens with device encryption, offers secure cloud backup, multi-device synchronization, offline mode, and import/export through QR, file, or manual input. Migration and restore tools reduce risk of token loss.
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
Protect your accounts with Proton Authenticator, a private and secure cross-device two-factor authentication (2FA) that works offline. Created by Proton, the creators of Proton Mail, Proton VPN, Proton Drive, and Proton Pass.
Bitwarden Authenticator generates verification codes for two-factor authentication, ensuring your identity is verified when you log into accounts.
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
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.
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.
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.
Sign in is easy, convenient, and secure when you use Microsoft Authenticator. Use your phone, not your password, to log into your Microsoft account. You simply have to enter your username, then approve the notification sent to your phone.
The only competitor to Authy. Try both and see what fits best for you.
It's an excellent replacement for the now dated Google Authenticator, it comes with enhanced security and backup/restore. You can use it across platform - but only in so much as it requires your phone to authenticate the code. It can not be duplicated yet into a cross platform cross browser version
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.
