 The User Manager is a tool that allows you to manage user accounts in Sitecore. You can use it to create, edit, delete, enable, disable, and unlock users. To unlock a user account, you need to open the User Manager, select the user, and click Unlock in the Users group on the navigation ribbon. This will reset the user’s failed login attempts and allow them to log in again. You cannot unlock a user account by changing their password, editing their settings, or updating their access rights. References: 1

 Sitecore headless development is based on a decoupled architecture where the rendering host is a separate application that handles the presentation logic and the Content Delivery role is a Sitecore instance that handles the content management and delivery. The rendering host communicates with the Content Delivery role using Sitecore headless services, which are APIs that expose Sitecore content and layout data in a JSON format. The rendering host translates a visitor request to a content item in the Sitecore instance. The Sitecore instance using Sitecore headless services returns the content item and the associated presentation details, and so on, to the rendering host. The rendering host renders the content item for the visitor. This way, the rendering host can use any technology or framework that supports HTTP requests and JSON parsing, such as ASP.NET Core, React, Angular, Vue, etc. References:

Field editor buttons are custom experience editor buttons that allow content authors to edit multiple fields of an item in a pop-up window. This is useful for complex fields that are not easily editable in the experience editor, such as multilist fields, checkbox fields, or image fields. Field editor buttons can also be configured to edit the fields of the data source item of a rendering, rather than the page item. Field editor buttons can improve the content authoring experience by providing a convenient and consistent way to edit fields in the experience editor. References:

 The field source is a property that you can set for some field types in a data template, such as Droplink, Droptree, Multilist, Image, File, and so on. The field source specifies the location of the items or media that the user can select from when editing the field. For example, if you have a Droplink field that allows the user to choose a category for an item, you can set the field source to point to a folder that contains the category items.This way, the user will only see the relevant items in the drop-down list. The field source can be a path, a GUID, or a Sitecore query that returns a single item or a list of items. The field source helps you to control the data source and the user interface for the field. References:
