az login still logged in successfully with wrong password in v2.5

[NTHieu95]

Describe the bug

I was expecting an error when I tried to do these steps:

• use azure cli v2.52
• run az login --service-principal --username <usrname> --password <pwd> --tenant <tenantname>
• run the above command again but with a wrong password

Expected: cannot log in

Actual: still be able to login with the wrong password

After finding around, i found out that in v2.52, it saves your logged in account in this az account show command. After run this command:
az account clear
And then run the login command with the wrong password, then it would meet my expectation. (I used to use az cli v2.3 and this never happened back then)

My main question is: is this considered a bug? And what other option for login do I have to use to make it fail at the second time logging in?
