    @sujith reddy komma ,

    I tested the process in my lab and it works for me.

    Policy Created using the PS Cmdlet:

        Set-AzureADPolicy -Definition @('{"TokenLifetimePolicy":{"Version":1,"AccessTokenLifetime":"23:00:00"}}') -Id "b477b9f2-3f7d-4ccf-a702-1af7224a8016" -IsOrganizationDefault $false -Type "TokenLifetimePolicy"  
    PS C:\windows\system32> $policyID = "b477b9f2-3f7d-4ccf-a702-1af7224a8016"  
    PS C:\windows\system32> $sp = Get-AzureADServicePrincipal -SearchString "Access"  
    PS C:\windows\system32> Add-AzureADServicePrincipalPolicy -Id $sp.ObjectId -RefObjectId $policyID  
    PS C:\windows\system32> Get-AzureADServicePrincipalPolicy -Id $sp.ObjectId  
    Id                                   DisplayName                       Type                IsOrganizationDefault  
    --                                   -----------                       ----                ---------------------  
    b477b9f2-3f7d-4ccf-a702-1af7224a8016 ExtendedAccessTokenLifetimePolicy TokenLifetimePolicy False  

    After that I tried getting an Access Token from Azure AD using the Authorization Code Grant Flow of OAuth2.0 protocol and got the token with the following lifetime mentioned:

    alt text

    Note: Inorder for this AzureADPolicy to work and provide you desired access token's lifetime, you need to keep in mind that when you make a request for the token by reaching the token endpoint of AzureAD, in the request body, for the resource parameter, you need to specify the "App ID" on whose corresponding Service Principal you have attached this Azure AD Policy.

    Note: This custom lifetime for Access Tokens, cant be set for first party resources like Graph API etc.

    Hope this helps.

    I assume you followed this guidance?
    Below is the code snippets to create a policy. Just validate that it is created.

    $policy = New-AzureADPolicy -Definition @('{"TokenLifetimePolicy":{"Version":1,"AccessTokenLifetime":"02:00:00","MaxAgeSessionSingleFactor":"02:00:00"}}') -DisplayName "WebPolicyScenario" -IsOrganizationDefault $false -Type "TokenLifetimePolicy"  
    Get-AzureADPolicy -Id $policy.Id  
    # Get ID of the service principal  
    $sp = Get-AzureADServicePrincipal -Filter "DisplayName eq ''"  
    # Assign policy to a service principal  
    Add-AzureADServicePrincipalPolicy -Id $sp.ObjectId -RefObjectId $policy.Id

    @soumi-MSFT @theodorbrander

    Thanks for the above

    I just want to increase the Access token lifetime of the APP that i created in Azure Active Directory

    the policy has bee created.i can verify that

    but when i run Get-AzureADServicePrincipal or Get-AzureADApplication neither this app or its object ID is visible in it. Is ti mandatory to create it at the Service Principal? How can i find my Servie Principal associated to this app? This policy has to be only assicated to one App registration which i created in the Azure Active DIrectory? is it posssible ?

    How can i create it?

    Hi Soumi,

    I tried with the object ID i have to get the Service Principal like below

    Get-AzureADServicePrincipal -ObjectId

    But i am not able to fetch it

    I have created my app in the portal and got the object ID from it.

    Do i need to add any permissions ?
