About this story

Priority: High
Story Points: Fibonacci Sequence: 5
Risk: High

Description:
Create additional 3rd party accounts for the application. Creating a 3rd party account will be possible directly from the admin dashboard. A menu will appear prompting the user to choose what type of account to create. Then, a form will appear to add information about the new user (all his info: email, etc). From there, a new user will be created to the database, and this email will be added to the 3rd-party user's list.

Exit Criteria
What should we expect once the task is complete:
-admin should be able to add 3rd party users to the application
-email should be sent to added 3rd party users prompting the user to choose his own password and activate his account.

Sub-Tasks/Steps

• Create a button to create in the admin dashboard.
• Create UI Form (to fill all missing info)
• Add the users to the right authenticated list (for permission)
• Add Form Validation (frontend-side/backend-side)
• Send an Email Invite to the new user to activate his account and create a pswd.
