Two factor authentication is used to secure access to a portal by checking the identity of the person connecting by linking two methods.
The technology chosen by alwaysdata is a Time-based One Time Password (TOTP) algorithm: sharing an individual and single use secret code between our database and the client secure authentication applications.
To use it, go to Profile > Security to activate Two factor authentication.
This will allow you access to your personal secret code and QR code.
Then you can configure your TOTP application that will send you a single use security code to be specified the next times you connect to your administration interface. This security code is renewed every 30 seconds (using a calculation based on the time or a meter).
