[id="mta-roles-personas-users-permissions_{context}"]
=== Roles, Personas, Users, and Permissions

{ProductShortName} makes use of three roles, each of which corresponds to a persona:

.Roles and personas
[cols="50%,50%", options="header"]
|====
|Role
|Persona

|`tackle-admin`
|Administrator

|`tackle-architect`
|Architect

|`tackle-migrator`
|Migrator
|====

The roles are already defined in your RHSSO instance. You do not need to create them.

If you are an {ProductShortName} administrator, you can create users in your RHSSO and assign each user one or more roles, one role per persona.

[id="mta-roles-personas-ui-views_{context}"]
==== Roles, personas, and access to {WebName} views

Although a user can have more than one role, each role corresponds to a specific persona:

* Administrator: An administrator has all the permissions that architects and migrators have, along with the ability to create some application-wide configuration parameters that other users can consume but cannot change or view. Examples: Git credentials, Maven `settings.xml` files.

* Architect: A technical lead for the migration project who can run assessments and can create and modify applications and information related to them. An architect cannot modify or delete sensitive information, but can consume it. Example: Associate an existing credential to the repository of a specific application.

* Migrator: A user who can analyze applications, but not create, modify, or delete them.

As described in xref:mta-ui-interface-views[User interface views], {ProductShortName} has two views, *Administration* and *Migration*.

Only administrators can access *Administration* view. Architects and migrators have no access to *Administration* view, they cannot even see it.

Administrators can perform all actions supported by *Migration* view. Architects and migrators can see all elements of *Migration* view, but their ability to perform actions in *Migration* view depends on the permissions granted to their role.

The ability of administrators, architects, and migrators to access the *Administration* and *Migration* views of the {ProductShortName} {WebName} is summarized in the table below:

In *Administration* view, you configure the instance environment, working with credentials, repositories, HTTP and HTTPS proxy definitions, custom migration targets, and issue management.

In *Migration* view, you perform application assessments and analyses, review reports, and add applications for assessment and analysis.
In *Migration* view, all authorized users can review reports, add applications for assessment and analysis. perform application assessments and analyses, create migration waves, view issues that could potentially impact migration, view the status of analysis and discovery tasks through Task Manager. The permissions of the different user roles -- administrators, architects, and migrators -- vary in this view.
