                                    can use authentik in an existing environment
                                    to add support for new protocols, implement
                                    sign-up/recovery/etc. in your application so
                                    you don't have to deal with it, and many other
                                    things.

                                    You can adopt authentik to your environment,
                                    regardless of your requirements. Need an Active-Directory
                                    integrated SSO Provider? Do you want
                                    to implement a custom enrollment process for your
                                    customers? Are you developing an application and
                                    don't want to deal with User verification and recovery?
                                    authentik can do all of that, and more!
