What Does Two-Factor-Authentication (2fa) Mean and How to Activate it for Leondrino Wallet?


To authenticate, as the name two-factor-authentication implies, customers need two factors to confirm their own identity. With Internet payments, from now on it is no longer sufficient to enter only the information about the means of payment. The identity of the customer must be additionally checked for most transactions, for example by a transaction number (TAN) and a password. This process is called two-factor authentication (2FA). There are three categories, from which such a factor can originate. If you want to make a payment, you must identify at least two factors from different categories. If this does not happen, payments can be rejected by the bank accordingly.

The categories read as follows:

  • Knowledge → PIN, access data, etc.
  • Ownership → TAN generator, smartphones with banking app or authenticator app, etc.
  • Inherence → Fingerprint, facial features or iris, etc.

You are requested to activate two-factor authentication for your Leondrino Wallet.

  1. Download an authenticator app on your mobile device. We recommend the following apps:
    – Google Authenticator
    – FreeOTP
  2. Then open this authenticator app and scan the barcode to be found in menu item “Authenticator” in profile view of your Leondrino Wallet.
  3. The authenticator app on your mobile device will show now that it is connected to your Leondrino Wallet. You should see a six-digit code (one-time code) and next to it Leondrino and your username enclosed in brackets.
  4. Now enter this six-digit one-time code from the authenticator app on your mobile device into the input field for the one-time code to complete the activation of the two-factor authentication in your Leondrino Wallet.

Once you have successfully completed steps 1 through 4, two-factor authentication is enabled for your Leondrino Wallet and you can use it to sign in and authorize transactions in your Leondrino Wallet.
