@Manish Arvind V, Thanks for posting in Q&A. Based as I know, the auto-logout behavior is by design for Microsoft 365, Azure, and Intune services. These services use cookies to remember who you are and to automatically sign you in. The sign-out process forces the session cookies to expire,
Unfortunately, there is no way to permanently stay signed in to these services. The auto-logout behavior is a security feature to protect your account.
Thanks for your understanding.
