Microsoft Teams: Admin setting for simpler meeting passcodes (numeric‑only)

Microsoft Teams will offer an admin setting to enable simpler 8-digit numeric-only meeting passcodes, off by default and requiring admin opt-in. This reduces passcode complexity but lowers cryptographic strength. The rollout begins March 2026, affecting only new meetings, with existing security controls unchanged.

[Introduction]

Microsoft Teams is introducing simplified meeting passcodes to reduce friction when joining meetings, especially when participants must manually enter a passcode. This feature is off by default and must be explicitly enabled by a tenant administrator.

This message is associated with Microsoft 365 Roadmap ID 555858.

[When this will happen]

• Targeted Release: We will begin rolling out in early March 2026 and expect to complete by mid-March 2026.
• General Availability
  • Worldwide & GCC: We will begin rolling out in mid-March 2026 and expect to complete by late March 2026.
  • GCCH & DoD: We will begin rolling out in early April 2026 and expect to complete by mid-April 2026.

[How this affects your organization]

Who is affected:

Tenant administrators who manage meeting security settings in Microsoft Teams.

What will happen:

• A new admin setting allows simplified 8‑digit numeric‑only meeting passcodes.
• The feature is off by default; admins must opt in.
• The setting can be applied to:
  • Specific users
  • Groups
  • The entire tenant
• Only newly scheduled meetings use numeric‑only passcodes.
• Existing meetings are not changed.
• If the feature remains off, Teams continues to use the default, more complex passcodes.

Security considerations:

• Numeric‑only passcodes reduce cryptographic strength relative to the default setting.
• The simplified passcode applies whether users join via meeting ID or by clicking a meeting link.
• Admins will see a security warning when enabling the setting.
• All other Teams meeting security controls remain unchanged, including:
  • Lobby and admission controls
  • Organizer and participant policies
  • Tenant authentication and access controls

[What you can do to prepare]

• Review your organization's meeting security requirements.
• Decide whether simplified passcodes meet your policies.
• If enabling, determine appropriate scope (users, groups, or tenant‑wide).
• If maintaining current behavior, no action is required.
• Consider updating internal documentation and informing helpdesk staff if you enable the feature.
