Connecting Tenants
Connect additional Microsoft 365 tenants and troubleshoot connection issues.
You can connect multiple Microsoft 365 tenants to a single 1Security account — useful for MSPs, holding companies, and organisations with several tenants.
Adding a tenant
Open the tenant menu
Click the tenant switcher in the top-left of the dashboard, then Add tenant.
Authenticate
A new tab opens to Microsoft's OAuth consent flow. Sign in with a global admin of the tenant you want to add.
Grant permissions
Approve the same permissions you granted during the initial install.
Wait for the initial scan
The new tenant appears in your switcher immediately, but full data takes the duration of the initial scan to populate.
Troubleshooting
Tenant permissions
1Security requests read-only permissions by default. Write permissions (used by automations) are opt-in per workflow.
The exact Microsoft Graph permissions requested:
- User.Read.All
- Group.Read.All
- Files.Read.All
- Sites.Read.All
- Directory.Read.All
- AuditLog.Read.All
- Policy.Read.All
- SecurityEvents.Read.All
