SSO and Microsoft Login
AB Projects uses Microsoft Single Sign-On (SSO) for secure, password-free access. You sign in with your existing Microsoft 365 account — on the web app and inside Microsoft Teams — with no separate AB Projects account or password to create.
How it works
- You sign in with your Microsoft 365 work or school account.
- There are no separate AB Projects passwords or credentials.
- Authentication is handled by the Microsoft Identity Platform (Microsoft Entra ID).
- Inside Teams, sign-in is automatic from your Teams session; on the web you authenticate with the same Microsoft account.
Access and membership
- Signing in establishes who you are. What you can see is your project membership, which follows the connected Teams channel — you're added automatically when the roster syncs (see Becoming a Project Member in AB Projects).
- There is no separate Microsoft 365 license to assign for AB Projects; access isn't gated on a per-user add-on license (see Managing Subscriptions & Billing for how plans work).
Benefits of Microsoft SSO
- Security: uses Microsoft's trusted authentication and identity controls (including your organization's MFA and conditional-access policies).
- Convenience: no extra accounts or passwords to manage.
- Onboarding: people already in the Teams channel get access without separate invites — the project roster syncs from the channel.
If sign-in fails
- Make sure you're using the Microsoft 365 account in the correct organization (tenant).
- If you can sign in but don't see a project, you may not be in the linked Teams channel yet, or the channel roster hasn't synced — have any channel member open the AB Projects tab to trigger a sync, then refresh (see Becoming a Project Member in AB Projects).
- Try signing in again, or clear your browser cache / reload the Teams tab.
- Your organization's conditional-access or consent policies may need an administrator to approve the app.
If problems persist, contact your Microsoft 365 administrator or our support team.
