This guide walks an organisation administrator through the complete setup process from creating a SemaFore organisation to having the first team member exchange encrypted messages.

Before you begin

You will need:

  • A mobile phone number capable of receiving SMS
  • A modern browser
  • At least one colleague to invite for the test

SemaFore is a business messaging platform. Organisation administrators manage the team from the web portal, while end users communicate via the iOS or Android app.


Step 1 — Create your organisation

Go to portal.semafore.io/signup.

Enter your phone number. SemaFore uses phone-number authentication only. There is no username or password.

Enter the six-character SMS OTP when it arrives.

Enter your organisation name and display name, then click Create organisation.

Information
The free tier supports up to 5 approved members. The portal Billing section also lets you start a 30-day Professional trial when you are ready to evaluate paid plan features.

Step 2 — Understand the portal

After sign-in you land on the portal dashboard. The main admin areas are:

SectionWhat it does
MembersInvite members, approve or deny devices, change roles, remove members
GroupsCreate, rename, archive, and manage group membership
BroadcastsSend one-way announcements to all approved members
Audit LogReview organisation activity events
BillingManage free-tier limits, trial status, and paid-plan billing
SettingsConfigure organisation-level options such as retention

Go to Members and click Invite member.

Enter the person’s phone number. The portal creates an invitation link using the universal-link format https://app.semafore.io/join/{token}.

Share that link with the invited person. If they already have the SemaFore app installed, opening the link takes them straight into the invitation flow. If they are signed out, the invitation is preserved through sign-in and resumed after OTP verification.

Information
SemaFore end-user accounts are identified by phone number. There is no email-based member login.

Step 4 — Wait for device registration

When the invited member signs in on the mobile app, their device registers automatically. You will see them appear in the Members list with status Registered or Pending approval.

At this point they still cannot send or receive messages.


Step 5 — Approve or deny the device

Review the registration and confirm with the person directly that they initiated it.

  • Click Approve to activate the device.
  • Click Deny if the registration is unexpected or should not proceed.
Warning
Approval is a deliberate security step. Do not approve a device registration you did not expect.

Step 6 — Exchange a first message

Once the member is approved, they can sign into the mobile app under the active organisation and start:

  • one-to-one conversations
  • group conversations
  • broadcast reads if you send organisation-wide announcements

The portal does not show message content. Message content is encrypted on-device before transmission, and the server stores ciphertext only.
