Convenience and security

The Protectimus Slim NFC hardware TOTP token is easy to configure, convenient, and reliable.


The programmable TOTP token Protectimus Slim NFC doesn't connect to the internet or to a GSM network, eliminating the possibility of a one-time password being intercepted when delivered in an SMS, or being read by malware on a smartphone. With this OTP token, unlike standard hardware tokens, only you will know your secret key, thanks to the setup over NFC.


The Protectimus Slim NFC was developed as a hardware alternative for the Google Authenticator and other OATH-compliant software OTP tokens. It's suitable for authentication systems that support TOTP tokens: Google, Facebook, VKontakte, Dropbox, GitHub, Kickstarter, Microsoft, TeamViewer, etc. If you're not sure whether this 2FA token is right for you, just ask us!


The Protectimus Slim NFC TOTP token can be programmed over NFC an unlimited number of times. This is convenient for businesses, as it allows the same token to be reassigned multiple times for use with different services, unlike non-programmable OTP tokens. It's convenient for clients, too, since the secret key can be changed if necessary.

Protectimus Slim NFC

Protectimus Slim NFC programmable hardware TOTP tokens are a more reliable alternative to applications for generating one-time passwords (Google Authenticator, FreeOTP, Duo Mobile, Authy, etc.) and SMS authentication. The OTP token's self-sufficiency provides comprehensive protection against the interception of one-time passwords and against their theft from a user's device that has become infected by malware.

The OTP tokens can be reprogrammed using the Protectimus TOTP Burner application for Android phones with NFC support. The user can assign a new seed (secret key) an unlimited number of times and can select the desired lifetime for generated OTPs: 30 or 60 seconds. The programmable Protectimus Slim NFC token is the most reliable, practical, and convenient solution for two-factor authentication (2FA).

Stylish design and reliability

The OTP token's IP68 protection rating guarantees that it is completely dust- and water-resistant; and thanks to its small form factor, your security token can always be with you.

Moisture and dust protection

The Protectimus Slim NFC OATH token is completely protected against dust and water getting inside. Its performance will not suffer even if immersed in water to a depth of up to 1 m. Despite this, we recommend handling the 2FA token with care to avoid diminishing its battery life or voiding the warranty.

The perfect size

The 2FA token Protectimus Slim NFC was developed with a convenient, stylish mini-card form factor and measures 64 mm x 38 mm x 0.9 mm. It fits comfortably in a purse or business card holder. Despite its small size, the Protectimus Slim NFC is a full-fledged two-factor authentication token.

Simple setup

All you need to configure our OTP token is an Android smartphone with NFC support and the Protectimus TOTP Burner application. Thanks to the app's intuitive, user-friendly interface, you can easily and quickly assign a secret key to the OTP token and select the required OTP lifetime (30 or 60 seconds).
