by This project source can be found on my github here.
This project is a single webpage to calculate time based tokens for two factor authentication, just like Google Authenticator or Authy does on your phone. There is no network connection necessary, so it can be used offline and you can be sure that I am not stealing your codes.
The project can be used live here.
The project uses the TOTP function from Bill St. Clair’s two factor authenticator. Additionally, QR codes can be uploaded to the site and parsed to get the two factor secret. I used the LazarSoft QR Reader library for that functionality.
