There is no AB Projects password. You sign in with the Microsoft 365 work or school account you already use for Teams, and Microsoft — not AB — verifies who you are. AB never sees or stores a password.
AADSTS50020. Use the account your company gave you — the one that belongs to your organization's tenant (your company's own space in Microsoft's cloud).How sign-in works
AB Projects uses single sign-on (SSO) — one Microsoft sign-in shared across your Microsoft 365 apps — handled by Microsoft Entra ID (Microsoft's cloud identity service, formerly Azure Active Directory). Because Microsoft does the authenticating, your organization's security rules — multi-factor authentication, conditional access — apply to AB automatically.
Any organization's Microsoft 365 tenant can sign in — your company doesn't need to be registered with us first. The only requirement is a work or school account.
Where you sign in
| Where you open AB Projects | What happens |
|---|---|
| Inside Microsoft Teams (desktop, browser, or mobile) | Sign-in is automatic from your Teams session — usually no prompt at all. |
| Your web browser | Open blz.actionbridge.io and sign in with the same Microsoft account. See Supported Platforms. |
| First use in your organization | Your Microsoft 365 administrator may be asked to approve the app's permissions once — see Why AB Projects Requires Microsoft Graph Permissions. |
Signing in is not the same as seeing projects
Sign-in establishes who you are. What you can see is decided by project membership, which follows the connected Teams channel — see Adding or Removing Members. And what you can edit can depend on licensing: the first 10 users are free, paid seats are $3/user/month on the Basic plan, and a member without a seat can sign in and view but is read-only — see Managing Subscriptions and Billing.
If sign-in fails
- Check the account. It must be a work or school account in the right organization. Error
AADSTS50020means you're signed in with a personal account or the wrong tenant — sign out of Microsoft, then sign back in with your company account. - Reload. Close and reopen the Teams tab, or clear your browser cache and sign in again at blz.actionbridge.io. For a tab that stays blank, see Microsoft Teams App Doesn't Load.
- You're in, but a project is missing? That's membership, not sign-in — you may not be in the linked Teams channel yet, or the roster hasn't synced. Have any channel member open the AB Projects tab to trigger a sync (see Adding or Removing Members).
- Ask your administrator. Your organization's conditional-access or consent policies may require an admin to approve the app once.
If problems persist, contact your Microsoft 365 administrator or our support team. In short: your Microsoft account is your AB account — there's nothing extra to create, remember, or reset.
