Getting Started

Sign up, set up your organization, and invite your team.

Signing up

Arca uses passwordless authentication. There are no passwords to create or remember.

  1. Go to the Arca login page and enter your email address.
  2. Check your inbox for an email from Arca with the subject “Sign in to Arca.”
  3. Click the Sign in button in the email. The link is valid for one hour.
  4. You'll be signed in and taken to the app.

Every time you sign in, you'll follow the same flow—enter your email, click the magic link. No password needed.

Completing your profile

The first time you sign in, Arca will ask you to complete your profile. Fill in:

  • First name and last name — Shown to your team in comments, assignments, and activity feeds.
  • Organization name — The name of your team or company. You can change this later in settings.

Once you complete your profile, Arca creates your organization and you're ready to start working.

Roles

Every organization member has one of three roles:

  • Owner — Full control over the organization. The person who creates the organization is automatically the owner. Owners cannot be removed.
  • Admin — Can invite and manage team members, update organization settings, and edit any request.
  • Member — Can create and manage their own requests, use libraries and playbooks, and view organization-visible content.

Inviting your team

Owners and admins can invite new members from the team settings page.

  1. Go to Settings → Members.
  2. Click Invite members.
  3. Enter the person's email address. You can optionally include their first and last name.
  4. Choose a role—Member or Admin.
  5. Click Send invite.

The invitee receives an email with the subject “You've been invited to join [your organization name].” The invitation link expires after 7 days.

Accepting an invitation

What happens when someone clicks an invitation link depends on whether they already have an Arca account:

New to Arca

  1. Click the invitation link in the email.
  2. Enter your first and last name on the acceptance page.
  3. Arca sends a magic link to verify your email.
  4. Click the magic link to create your account and join the organization.

Already have an account

  1. Click the invitation link in the email.
  2. If you're already signed in with the matching email, you'll be added to the organization automatically.
  3. If you're not signed in, you'll be prompted to sign in first, then join the organization.

Managing your team

Owners and admins can manage team members from Settings → Members:

  • Change roles — Click a member's row to update their role between Member and Admin.
  • Remove members — Remove someone from the organization. They will lose access to all organization resources.
  • View pending invites — See invitations that haven't been accepted yet, along with their expiration status.
  • Revoke invites — Cancel a pending invitation if it was sent in error.

Regular members can view the team list but cannot invite or manage other members.

Organization settings

Owners and admins can update the organization from the settings page:

  • Organization name — Change your team's display name (up to 21 characters).
  • Description — Add a description for your organization.
