Hi @Mahavir Saroj ,
Thanks for reaching out.
Azure Bastion can be used to log in with Microsoft Entra ID authentication using Azure CLI and the native RDP client mstsc.
The native client feature allows you to connect to your target VMs via Bastion using Azure CLI, and expands your sign-in options to include local SSH key pair and Microsoft Entra ID.
Please note - Microsoft Entra Guest Accounts can't connect to Azure VMs or Azure Bastion enabled VMs via Microsoft Entra authentication.
Hope this will help.
Thanks,
Shweta
