The First TOTP Tokens with Time Synchronization Protectimus Slim NFC Are Going on Sale on May 1
Protectimus Solutions LLP is announcing the sale of its reflashable TOTP tokens featuring time synchronization.
By: Protectimus Solutions LLP
The programmable Protectimus Slim NFC hardware tokens are designed to replace software tokens (one-time password generator apps, like Google Authenticator, Protectimus Smart OTP, etc). If a site offers a two-factor authentication feature for account protection but doesn't support hardware tokens itself, users can simply connect the Protectimus Slim NFC TOTP token instead of an app.
The only disadvantage of this token to date was the possibility of time drift. This problem is inherent to all TOTP tokens, without exception. TOTP tokens contain an on-board clock. Inevitably, the clock gradually gets ahead of or falls behind the actual time. Per RFC 6238, the time difference between the token and server should be monitored by the server software.
But users often don't have access to the authentication server, so Protectimus figured out a way of correcting the token's clock instead. The time will be resynchronized when a secret key is flashed to the token.
The token can be reflashed using the Protectimus TOTP Burner application. Currently, the app is available for Android only. The app scans a QR code containing the secret key, and then transmits that secret key to the Protectimus Slim NFC token. As it does so, it sets the correct time. An Android smartphone used for this purpose must support NFC.
Here are some of our clients who are already using Protectimus Slim NFC OTP tokens: Middle Tennessee State University, the George Washington University, the College of Central Florida, the University of Guelph, the University of Groningen, the London Science Museum, and many other companies. These tokens are often purchased for personal use with Google, Office 365, Azure MFA, Facebook, Dropbox, Github, payment systems, and cryptocurrency exchanges.
