Collaboration in Fusion Hubs
Fusion Hubs: Invite Users
How to invite users to a Fusion Hub.
Users that are Tenancy Manager in a Fusion Hub are able to send invites:
Individual invites to Fusion Hubs
- Login to DekkoCORE
- In the top of the dashboard select the Hub you want to invite user(s) to
- In the left navigation panel select Invite users
- Fill out the email of the person you would like to add and click Invite


Fusion Hubs does not have user types, instead a user can be added to a sharing group after being invited to the Hub.
Create a user account (without sending an invite)
Tenancy Managers can create a DekkoCORE account directly, instead of inviting someone by email. This is useful when a person needs access but should not be identified by an email address, or when you want to set up their access yourself before handing it over.
A created account works as soon as you save it. DekkoCORE does not send the person any email, so you are responsible for passing on their sign-in details.
How created users differ from invited users
When you invite someone, or when a user with invite permission invites them, the person registers with their email address and receives email notifications about activity on their account. A created user is different in two ways.
Their User ID cannot be an email address. It is a name you choose, such as john or john.v, and they sign in with exactly that ID.
If you need to create an account that uses an email address as its User ID, contact your DekkoSecure account manager to request an exception.
Created users do not receive email notifications about activity associated with their DekkoCORE account, such as files shared with them or Hub updates. Let the person know they will need to sign in to DekkoCORE to see new activity.
Create the user
- In the Tenancy Manager, select Users under Tenancy Admin in the left menu.
- Select Create user. The Create user window opens, showing the name of your tenancy.
- Enter a User ID. This is the name the person will sign in with. It cannot be an email address.
- Enter the person's Full name. This is how they appear to other users.
- Enter a Password, then enter it again in Confirm password. Select the eye icon if you want to check what you have typed.
- Under Hubs, choose which Hubs the person should belong to. Use Filter hubs to find a Hub by name, and use the All Hubs, Member and Not a member tabs to switch between views. For each Hub you add, select the person's role from the dropdown next to the Hub name (for example, External).
- Even if you don’t select any Hubs, the user will be added as an individual in the Fusion users section (they won’t be added to any sharing configurations).
- Select Create.

Fusion Hub access
A created user is given your tenancy's Fusion key when the account is made. This means files in Fusion Hubs can be shared with them straight away, without waiting for them to sign in first.
Sharing the sign-in details
You need to give the person their User ID and password yourself. Use a secure method, and where possible send the User ID and the password through separate channels (for example, the User ID by email and the password by phone or in person). Avoid sending both in the same message.
Two-factor authentication and passkeys
Created users follow the same security policies as everyone else in your tenancy. If your tenancy enforces two-factor authentication or passkeys, the created user must meet those requirements to access their account, just as an invited user would. Let the person know to expect this setup step when they first sign in.
Create user groups
Access in a Fusion Hub is given to groups and individuals. These parties are created and managed in the Tenancy Manager, and the same group can be used in any Fusion Hub in the tenancy.
Select User groups in the Tenancy Manager. The list shows each group with its number of members. Entries marked Individual are groups of one person, which DekkoCORE creates when someone is invited from the file management interface.

Create or edit a group
- Select Create group, or select the ... menu on an existing group and choose to edit it.
- Enter a Name.
- In Add member, type a name or an email address. An email address invites the person, and they can be outside your tenancy.
- To add many people at once, select Import from CSV.
- To remove someone, select the cross beside their name in the Members list.
- Select Save group.

What happens when membership changes
When you add someone to a group, they get access to everything that group can access in every Hub where the group is active. This includes files uploaded before they were added, and the access takes effect almost immediately.
When you remove someone from a group, their access ends straight away, unless they belong to another group that is active in the same Hub.
Share files with an unregistered user
Need to share with someone who doesn’t have a DekkoSecure account! The share-and-invite feature makes this easy - no separate invites required.
- Upload the files, select them, and click Share
- Add the email addresses of the users that need access
Users that are new to DekkoSecure (and new to the Hub) will be marked with (Invited when you save)
- Set the appropriate access permission and then press Save Changes. Your invitee will be able to access shared files after they create an account using their invite.
Invite delivery troubleshooting
If your invitees can’t find your invite(s):
First - double-check if the invitee’s email address has been entered correctly. To remove any doubt, the best method is to copy and paste the address from your mail client.
Invitees should check their spam/junk folder or the “Other” inbox in Outlook.
If the invite cannot be found then your invitee will need to check if the DekkoSecure system notification address are being blocked by their IT administrator. If this is the case and it has been rectified you will need to re-send your invite.
If any issues persist please create a support ticket - our support team will be able to investigate whether your invites are being blocked.
