The handoff problem
A team may depend on a single employee to read an authenticator code whenever someone signs in. That person becomes a bottleneck, especially across time zones or during leave. Copying a setup secret into a chat solves the immediate problem but leaves a permanent copy that is difficult to track.
A shared group
Team2FA organizes authenticator entries inside an organization. An owner can place one entry in several code groups and give specific people or user groups Viewer, Editor or Admin access. A member requests the current code when needed, and the application records code issuance without writing the code itself to the audit event.
The boundary
Sharing a TOTP seed means anyone who previously copied it may still generate codes outside the product after access is removed. Rotate the seed at the external service when somebody leaves a sensitive role. Require MFA for the underlying service and review its active sessions separately.
