# Setup Multi-Factor Authentication

As an open-appsec Premium Edition subscriber multi-factor authentication (MFA) is available for strong user authentication of your open-appsec web UI tenant.

## How to activate MFA / 2FA

In order to activate 2FA for your tenant, please send us an email to <info@openappsec.io> and request activation, providing also your tenant ID or alternatively open a support request directly from your tenant.

In the future you will also be able to activate this directly from the open-appsec web UI.

Once 2FA was activated for a tenant, when any tenant user logs in who didn't use 2FA so far, he will be shown the QR code for registering the open-appsec 2FA authentication in his authenticator app (you can use e.g. the Google Authenticator or Microsoft Authenticator app for this) and be asked to confirm the correct registration in his authenticator app by entering a correct one time code from his authenticator app.

From now on that user will be required to provide his one-time-code in addition to the regular sign-in, see screenshots below.
