Obsidian Elegant OTP Authenticator Alternatives

Best for: Mobile 2FA app with encrypted backup and sync

Authy is a mobile 2FA app from Twilio for generating login codes with encrypted backups and multi-device sync. It is useful for users who want recovery options beyond a single phone, but it is no longer a desktop authenticator: Twilio says the Windows, macOS, and Linux desktop apps reached end of life on March 19, 2024.

Pricing: Authy mobile is marketed as free; desktop apps are no longer supported.

Best for: Simple TOTP/HOTP code generator with optional Google sync

Google Authenticator is a mainstream mobile authenticator for generating one-time verification codes. It works offline after setup, supports QR-code enrollment, and can optionally sync codes with a Google Account. It suits users who want a simple app and are comfortable with Google account-based recovery.

Pricing: No paid authenticator subscription was found on the official app listings.

Best for: Open-source HOTP/TOTP authenticator for mobile

FreeOTP is an open-source two-factor authentication app associated with Red Hat. It supports systems using one-time password protocols and lets users add tokens by scanning QR codes. It is a practical choice for users who prefer a small, standards-based authenticator for Android or iOS.

Pricing: Free app; no subscription pricing found on official listings.

Best for: Legacy open-source Android OTP app

andOTP was an open-source Android authenticator with TOTP/HOTP support, but the project is archived and marked unmaintained. Existing users may still need migration information, yet new users should choose an actively maintained authenticator such as Aegis, 2FAS, Ente Auth, Proton Authenticator, or Bitwarden Authenticator.

Pricing: Free/open-source historical app; not a current maintained recommendation.

Best for: Portable desktop authenticator for Windows

WinAuth is a portable open-source Windows authenticator for RFC 6238 time-based or counter-based codes, including Google Authenticator-style tokens and several older game/service authenticators. It can fit desktop-only workflows, but editors should review maintenance age and download source before recommending it as a primary choice.

Pricing: Free/open-source Windows utility.

Best for: Historical MFA/passwordless product entry

UNLOQ appears to have been a passwordless or MFA product and plugin ecosystem, but current public results mostly point to old plugin pages or an unrelated UNLOQ business site. Treat this entry as stale until an official active authenticator or MFA product page is verified.

Pricing: Current pricing could not be verified.

Best for: Hardware-backed MFA with optional authenticator codes

YubiKey is a hardware security key family from Yubico rather than a pure software authenticator. With Yubico Authenticator, TOTP credentials can be stored on a YubiKey and accessed across desktop and mobile apps. It is relevant for users who want hardware-backed MFA and are willing to buy a physical key.

Pricing: Requires buying a compatible YubiKey; app availability is separate from hardware cost.

Best for: Mobile authenticator for LastPass and TOTP services

LastPass Authenticator provides TOTP codes and push approval for LastPass and other TOTP-compatible services, with secure cloud backup. It is most relevant for users already in the LastPass ecosystem or teams that want a mobile authenticator aligned with LastPass account security.

Pricing: Authenticator app is available free; LastPass vault plans are separate.

Best for: Enterprise MFA app with push approvals and passcodes

Duo Mobile is built around Cisco Duo's managed MFA service, while also generating passcodes for other compatible services. It is strongest for organizations that need push approvals, device-health checks, restore workflows, and administrator policy control rather than just a personal code generator.

Pricing: Mobile app is free; Duo service plans are commercial for organizations.

Best for: Open-source OTP app with optional self-hosted sync

Open Authenticator is an open-source cross-platform OTP project that emphasizes transparency, interoperability, and optional self-hosted sync. Because it is less established than major authenticator apps, verify release activity, mobile store links, and support expectations before publishing it as a mainstream recommendation.

Pricing: Open-source project; current hosted or app-store pricing needs review.

Best for: Windows TOTP manager for business and Exact Online workflows

Invantive Authenticator is a Windows TOTP tool aimed at users who manage many two-step verification accounts, especially around Invantive and Exact Online workflows. Its documentation highlights RFC 6238 support plus export/import options, but the page should disclose its niche Windows focus.

Pricing: Official manual describes the software as a free download.

Best for: Discontinued password manager and authenticator

Myki was an offline password manager and authenticator, but it was discontinued after JumpCloud acquired Myki Security. Do not present it as a live alternative to Obsidian Elegant OTP Authenticator; keep it only as a historical entry or mark it for removal and replacement.

Pricing: No current pricing; product was discontinued in 2022.

Best for: Ambiguous authenticator listing requiring vendor mapping

This item is too generic to verify safely. There are many unrelated apps called Authenticator or Authenticator App across app stores and browser stores. Before updating the listing, map it to the exact provider, app-store ID, official website, privacy policy, and current pricing model.

Pricing: Unknown until the exact app/provider is identified.

Best for: Legacy multi-device authenticator with sync

Authenticator Plus offered synchronized 2FA codes across Android, iOS, tablets, and wearable devices, but current evidence points to an old or possibly abandoned app. Treat it as a legacy entry; users should verify store availability, export options, and backup reliability before relying on it.

Pricing: Legacy product; current pricing and store availability need review.

Best for: Microsoft-focused MFA app with TOTP and passwordless sign-in

Microsoft Authenticator is a mainstream mobile MFA app for Microsoft personal, work, and school accounts as well as other TOTP services. It supports passwordless sign-in, push approvals, and offline one-time codes, but Microsoft notes that the app is designed for iOS and Android rather than PC or Mac.

Pricing: Free mobile app; enterprise identity features may depend on Microsoft plans.

Best for: Free 2FA app with mobile and browser-extension workflow

2FAS is a free, privacy-oriented authenticator for two-factor authentication codes, with mobile apps and a browser extension workflow for easier sign-ins. It is a strong replacement candidate for users who want an actively maintained app, simple migration, and less account lock-in than older authenticators.

Pricing: Official site and store listings present the authenticator as free.

Best for: Open-source Android authenticator with encrypted backups

Aegis Authenticator is a free, open-source Android app for managing 2FA tokens. It supports HOTP and TOTP, focuses on local vault security, and is a good fit for Android users who want an actively maintained open-source replacement for archived projects like andOTP.

Pricing: Free/open-source Android app.

Best for: Cross-platform 2FA app with E2EE sync

Ente Auth is an open-source authenticator with end-to-end encrypted backups and cross-platform sync. It is useful for users who want the convenience of cloud recovery without leaving OTP secrets readable to the provider, plus access across mobile, desktop, and web.

Pricing: Authenticator is presented as free; verify any future plan changes on the official site.

Best for: Standalone TOTP app from Bitwarden

Bitwarden Authenticator is a standalone mobile app for generating TOTP verification codes. It can be used without a Bitwarden Password Manager account, while users who also use Bitwarden can evaluate optional code synchronization with their vault workflow.

Pricing: Standalone Bitwarden Authenticator is free; Bitwarden Password Manager premium TOTP is separate.

Best for: Free cross-platform authenticator with encrypted sync

Proton Authenticator is a free, open-source 2FA app with end-to-end encrypted sync, encrypted backups, offline access, import/export options, and desktop plus mobile apps. It is a good replacement candidate for users who want cross-platform access without ads or tracking.

Pricing: Proton says the authenticator is free to use on desktop and mobile.
