The Token2 miniOTP card is a hardware alternative to Google Authenticator or other OATH-compliant software tokens. It works with authentication systems that support TOTP tokens: Google, Facebook, Fortnite, Coinbase, GDAX, Dropbox, GitHub, Kickstarter, Microsoft, TeamViewer, Stripe, Azure, etc. Program the card using your NFC-enabled Android/iOS phone by scanning a QR barcode. How to set up the token: 1. If you have an NFC-enabled phone running Android or iOS, just download and run the Token2 app from your app store. 2. Initiate the token setup on the website/system where you require enhanced security. 3. Save the secret key in a SAFE place so that you can easily restore the security token. 4.Scan the secret key using the Token2 app, or input it manually. We recommend the automatic method. 5.Activate the OTP token and place it near your phones NFC antenna. While holding it near the NFC antenna, tap "Burn the seed" and wait for a message confirming that the 2FA token was programmed successfully. The miniOTP-2-i features unrestricted time sync to allow the internal clock to be kept up to date. This can eliminate issue with drift accumulating over several years where the clock drifts outside the synchronization window.
