[Two factor authentication](https://en.wikipedia.org/wiki/Multi-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](https://en.wikipedia.org/wiki/Time-based_One-time_Password_algorithm) (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** 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).

> [!NOTE]
> In the case of loss of two-factor authentication, send an email to *contact[at]alwaysdata.com* to deactivate it. [A verification will be carried out](/en/docs/admin-billing/profile/admin-access-loss#blockage-related-to-two-factor-authenticationhahahugoshortcode-s0-hbhb).
