Project Users

To be able to work with KBC, each user needs the following:

  • Platform wide KBC account
  • Access to a specific project

Once users can access a project, they gain full administrative access to that project. Each user is, system-wide, identified by their email address. This means that you need to enter correct email addresses for existing users. Be especially careful about company aliases; from KBC’s point of view, they are different users.

All operations done by a user are technically done using the master token. This is important for tracing operations done by that user.

Inviting a User

If you want to add a new user to the project, go to Users & Settings in the project and click the Add new user button:

Enter the user’s email:

The user is added to the project:

New User

If the user does not yet have a platform wide KBC account, their user list names will be shown as Not activated yet and they will receive an invitation email:

When they follow the link, they will be taken to the activation form:

After that, the users will be taken to the login form. They can immediately login to KBC and see the project they have been invited to. In the User list, you will see their chosen screen name:

Existing User

If the added user already has a KBC account, you will immediately see their screen name in the user list:

Verify the screen name if you intend to invite an existing user. If you see Not activated yet instead of the screen name, it means that there is no KBC account associated with the email address. The user can then immediately enter the project, and they will also receive an email invitation:

The link will simply take them to the login form (or the project list if already logged in).

Registering Manually

It is also possible to create a KBC account manually by following the Sign Up link from the login page:

Then fill the registration form:

You will then receive a confirmation email with a link to activate the new KBC account.

If you have a Gmail account, go to the login page and then straight to Sign in with Google:

Once you authorize KBC in your Google account, a KBC account will be created for you automatically.

Important: If you register to KBC manually, you cannot actually do anything unless someone invites you to a project.

Removing a User

You may remove a user from a project by clicking the Remove button in the user list. The user will receive a notification email about being removed from the project. The removal is effective immediately. Any following operations will be unauthorized, regardless of whether the use was currently logged in or not. Removing a user from a project has no effect on the data in the project; everything that particular user did in the project stays untouched. You can also leave a project voluntarily by pressing the Leave button.

Important: However, you will not be able to re-join the project unless someone invites you again.


There are three options for authenticating a KBC account:

  • Google account
  • Combination of an email address and a chosen password
  • Combination of an email address and a chosen password with multi-factor authentication

The options are described in detail below.

Google Account

If you have a Google Account (Gmail), you can use it to authenticate to KBC. Simply click the respective button on the login page

and follow the Google instructions to authorize KBC. No configuration in KBC is necessary to enable Google Account login. Bear in mind, however, that the Google Account email must match the email you are using in KBC.

Multi-Factor Authentication

Enable multi-factor authentication (MFA) in your account settings. You can review the state of MFA for any user in the user list:

All users listed on the Users & Settings page are project administrators. This means they can do all operations within the project. If you need to limit authorization to certain operations or data, there are two options to choose from:

  1. Split the project into multiple projects, or
  2. Use Storage Tokens instead of full user accounts.
