Hi, @Priya Jha Thanks for posting your question on the Microsoft Q&A platform.
As I understand from the question, you want to know if there is possible to login into Azure SQL DB via Personal Access Token.
Azure AD supports token-based authentication for applications connecting to SQL Database and SQL Managed Instance.
If you're working within Microsoft tools, then your Microsoft account (MSA) or Azure Active Directory (Azure AD) is an acceptable and well-supported approach. But, if you're working with third-party tools that don't support Microsoft or Azure AD accounts – or you don't want to provide your primary credentials to the tool – use PATs to limit your risk.
Please refer to this document here
Please provide more information on your use case so I can provide additional details.
Regards
Geetha
