Hi Fuzie,
In Microsoft Entra Identity, users with Global Reader permissions do not have access to view the "last sign in time" for users directly in the All Users blade. This information is typically visible only to roles with more access, like Global Administrators.
While Entra's Usage and Insights reports and Microsoft Graph can provide some sign-in data, they may not present it in the exact format seen in the All Users blade for Global Administrators.
However, if you want to be able to view these information, there are roles other than Global Administrator that typically have the ability to view detailed sign-in data, such as "last sign in time," include:
Security Administrator: This role has extensive permissions to manage security-related features, including sign-in logs and reports.
Reports Reader: Specifically designed to view various reports within the environment, including sign-in and usage reports.
These roles have more access to detailed sign-in information compared to Global Readers, while not providing the full range of permissions granted to a Global Administrator. Assigning one of these roles would allow a user to view the last sign-in times for users within the organization.
