unable to login to azure portal via az login command

Hello @SHANTANU TALUKDER

The Azure CLI's default authentication method for logins uses a web browser and access token to sign in. As suggested by Babafemi You need to specify the tenantid, in your current session you just have to do it once and from then on it won't require that.

az login --tenant <TenantID>

If you have already done that and the issue remains same, you can follow the link to another similar question that has a few more suggestions which worked for other users with the same error you have encountered here

Hello SHANTANU TALUKDER,

Thank you for posting your query in the Microsoft Q&A Community.

I understand that you are experiencing issue authenticating with your user account via CLI

Based on your screenshots, one reason why you might be experiencing this is trying to authenticate to a different tenant other that the tenant where the subscription is.

To resolve this, kindly force the authentication by adding your tenant id

az login --tenant 00000000-0000-0000-0000-000000000000

If you are in the tenant and you still not able to access, you can set the subscription using this

az account set --subscription "<subscription ID or name>"

Let me know if further assistance is needed.

I have a similar issue.

az login and az login --tenant <TenantID> does not work.

In my case it's because I run powershell or terminal as administrator (it was working with previous versions of azure cli).

So there is a bug if you login into azure cli from powershell or terminal opened as administrator.
