In this article, you will find everything you need regarding security within Umbraco.

    The Umbraco Trust Center

    On our main website, we have a dedicated security section which provides all the details you need to know about security within the Umbraco CMS. This includes how to report a vulnerability.


    We highly encourage the use of HTTPS on Umbraco websites, especially in production environments. By using HTTPS you greatly improve the security of your website.

    In the "Use HTTPS" article you can learn more about how to use HTTPS and how to set it up.

    Backoffice users and website members (Available from Umbraco version 9.3.0)

    Authentication for backoffice users and website members in Umbraco uses ASP.NET Core Identity which is a flexible and extendable framework for authentication.

    Out of the box Umbraco ships with a custom ASP.NET Core Identity implementation which uses Umbraco's database data. Normally this is fine for most Umbraco developers, but in some cases the authentication process needs to be customized.

    External login providers

    The Umbraco users and members supports external login providers (OAuth) for performing authentication of your users/members. This could be any OpenIDConnect provider such as Azure Active Directory, Identity Server, Google or Facebook.

    Two-factor authentication (Available from Umbraco version 9.3.0)

    The Umbraco members supports a two-factor authentication (2FA) abstraction for implementing a 2FA provider of your choice. This could be any Time-based One-time Password (TOTP) Algorithm, including Microsoft and Google Authenticator Apps

    BackOfficeUserManager and Notifications

    The BackOfficeUserManager is the ASP.NET Core Identity UserManager implementation in Umbraco. It exposes APIs for working with Umbraco Users via the ASP.NET Core Identity including password handling.

    Custom password check

    In most cases External login providers (OAuth) will meet the needs of most users when needing to authenticate with external resources but in some cases you may need to only change how the username and password credentials are checked.

    This is typically a legacy approach to validating credentials with external resources but it is possible.

    You are able to check the username and password against your own credentials store by implementing a IBackOfficeUserPasswordChecker.

    Sensitive data on members

    Marking fields as sensitive will hide the data in those fields for backoffice users that do not have permission to view personal data of members.

    Learn more about this in the Sensitive Data article.
