Enabling 2FA will prohibit multi-point sign-in on a single device, allowing only single sign-in across dual devices.

Examples of restricted multi-point login on a single device are as follows:
1. Allowed: Users can log in on the same browser with different tabs (e.g., multiple pages in the same web browser). This counts as a single-point login, and users can maintain their login across different tabs.

2. Prohibited: Users logging in simultaneously on different browsers will be considered multiple-point logins. In this case, the user will be automatically logged out from the previous session.
