Source: https://altcatalog.com/alternatives/authy/ Category: Authenticator apps ## Where Authy stands out - **Push-based approvals** — 3 of 7 apps with a verified answer have this - **Multi-device sync** — 4 of 10 apps with a verified answer have this ## Overview - **Who it's for**: Individuals who want stronger login security than passwords alone, especially anyone juggling 2FA codes across many online accounts and multiple phones or tablets. - **What you get**: A free authenticator app that generates time-based one-time passcodes (TOTP) for two-factor authentication. Codes are backed up to an encrypted cloud backup and synced across devices, so losing a phone doesn't mean losing access to your accounts. Desktop apps were discontinued by Twilio in 2024; only the iOS and Android mobile apps remain actively supported. - **How it works**: You add an account by scanning a QR code or entering a setup key from the service you're securing, and Authy generates a rotating 2FA code you enter alongside your password at login. The encrypted backup keeps those accounts synced if you install Authy on a new or additional device. ## Profile - **License**: Proprietary (verified 2026-07-11) - **Pricing model**: Free (verified 2026-07-11) - **Starts at**: ? - **Platforms**: iOS, Android - **Status**: active (verified 2026-07-11) ## Ranked alternatives | # | App | Alt Score | Licence | Platforms | |---|-----|-----------|---------|-----------| | 1 | [2FAS](https://altcatalog.com/alternatives/2fas.md) | 85 | GPL-3.0 | iOS, Android, Browser extension | | 2 | [Stratum](https://altcatalog.com/alternatives/stratum.md) | 75 | GPL-3.0 | Android | | 3 | [Ente Auth](https://altcatalog.com/alternatives/ente-auth.md) | 70 | AGPL-3.0 | iOS, Android, Windows, macOS | | 4 | [Aegis Authenticator](https://altcatalog.com/alternatives/aegis-authenticator.md) | 60 | GPL-3.0 | Android | | 5 | [Duo Mobile](https://altcatalog.com/alternatives/duo-mobile.md) | 55 | Proprietary | iOS, Android | | 6 | [FreeOTP](https://altcatalog.com/alternatives/freeotp.md) | 55 | Apache-2.0 | iOS, Android | | 7 | [Google Authenticator](https://altcatalog.com/alternatives/google-authenticator.md) | 55 | Proprietary | iOS, Android | | 8 | [Microsoft Authenticator](https://altcatalog.com/alternatives/microsoft-authenticator.md) | 45 | Proprietary | iOS, Android | | 9 | [Yubico Authenticator](https://altcatalog.com/alternatives/yubico-authenticator.md) | 40 | Apache-2.0 | iOS, Android, Windows, macOS | Alt Score = Verified coverage (90%) + Visibility (10%).
