Source: https://altcatalog.com/alternatives/yubico-authenticator/ Category: Authenticator apps ## Overview - **Who it's for**: People and organizations who already use (or want to use) a YubiKey and want to move their 2FA/TOTP secrets off their phone or password manager onto dedicated hardware, for stronger protection against phishing and malware. - **What you get**: A free companion app for Windows, macOS, Linux, iOS, and Android that manages TOTP/HOTP accounts stored on a YubiKey rather than on the device itself. Credentials live in the YubiKey's secure element and can't be extracted, and the same key can be used across multiple computers or phones. Setup is via QR code scanning, and the app lets you view, add, rename, and delete accounts on the key. - **How it works**: You register an account by scanning its QR code, which writes the secret to the YubiKey (over USB or NFC) rather than to the app. To get a code, you connect or tap the YubiKey to your device and the app reads the current TOTP/HOTP code from it, so codes are only generated while the physical key is present. ## Profile - **License**: Apache-2.0 (verified 2026-07-11) - **Pricing model**: Free (verified 2026-07-11) - **Starts at**: ? - **Platforms**: iOS, Android, Windows, macOS, Linux - **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 | [Authy](https://altcatalog.com/alternatives/authy.md) | 55 | Proprietary | iOS, Android | | 6 | [Duo Mobile](https://altcatalog.com/alternatives/duo-mobile.md) | 55 | Proprietary | iOS, Android | | 7 | [FreeOTP](https://altcatalog.com/alternatives/freeotp.md) | 55 | Apache-2.0 | iOS, Android | | 8 | [Google Authenticator](https://altcatalog.com/alternatives/google-authenticator.md) | 55 | Proprietary | iOS, Android | | 9 | [Microsoft Authenticator](https://altcatalog.com/alternatives/microsoft-authenticator.md) | 45 | Proprietary | iOS, Android | Alt Score = Verified coverage (90%) + Visibility (10%).
