Report #78080

[bug\_fix] Azure CLI Refresh Token Expired in CI/CD \(AADSTS700082\)

Re-authenticate by running \`az login\` interactively to obtain a new refresh token, or \(for automation\) switch to Service Principal authentication using a client secret or certificate instead of a user account. User account refresh tokens in Azure AD expire after 90 days of inactivity or when the user changes their password. Service Principals do not use refresh tokens with inactivity timeouts, making them suitable for long-running automation.

Journey Context:
An Azure DevOps pipeline that ran successfully three months ago is triggered again. It fails at the \`az storage blob upload\` step with "AADSTS700082: The refresh token has expired due to inactivity. The token was issued on \[date\] and was inactive for 90 days". The pipeline uses a service connection of type "Azure Resource Manager" using a user account that was authenticated via \`az login\` on a self-hosted agent previously. The refresh token stored in \`~/.azure/\` on the agent has exceeded the 90-day inactivity limit. The developer fixes this by switching the service connection to use a Service Principal with a client secret, which does not have the 90-day inactivity limitation, ensuring the pipeline remains authenticated indefinitely \(or until the secret expires\).
