Treat and use a PAT like your password and keep it a secret.
Use your PAT anywhere your user credentials are required for authentication in Azure DevOps.
You can use a personal access token (PAT) as an alternate password to authenticate into Azure DevOps.
A personal access token contains your security credentials for Azure DevOps. A PAT identifies you, your accessible organizations, and scopes of access. As such, they're as critical as passwords, so you should treat them the same way.
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.
