Protectimus SMART review
A free iOS and Android authenticator with broad OTP support and mobile-focused coverage.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Protectimus SMART is a free mobile two-factor authentication app for individuals and organizations using Protectimus MFA services or websites that support compatible authentication methods. It generates HOTP, TOTP and OCRA one-time passwords, supports both 6-digit and 8-digit OTPs, and can approve supported sign-ins through push notifications. The app is available for iOS and Android, making it a focused choice for users who want core authenticator functions on a phone rather than a broader cross-platform setup.
Its main strength is the combination of authentication coverage and migration tools. The Free plan includes encrypted cloud backup, token transfer to a new phone and Google Authenticator token import. PIN and biometric protection add local access controls, while token folders and customization with emojis and descriptions help organize multiple accounts. These features make the app a practical fit for users moving from Google Authenticator or managing several tokens on a mobile device.
The main consideration is ecosystem fit. Protectimus SMART is limited to iOS and Android, and the published positioning does not verify multi-device synchronization. Push approvals are described as part of the Protectimus authentication solution and may require Protectimus MFA service backend support, so they are not equivalent to a universally available approval flow for every account. Choose Protectimus SMART if free mobile OTP generation, encrypted backup, token transfer and optional push approvals match your requirements. Choose an alternative if you need broader platform coverage or verified synchronization across multiple devices.
