[bug\_fix] AADSTS700082: The refresh token has expired due to inactivity \(Azure AD\)

Run \`az login\` again to obtain a new refresh token. The root cause is that Azure AD refresh tokens have a default maximum inactive lifetime of 90 days \(configurable by tenant admin\). If the user does not actively use the token to get new access tokens within that window, the refresh token is purged.

Journey Context:
A developer uses Azure CLI for occasional resource management. They haven't run \`az\` commands for months. They run \`az group list\` and get "AADSTS700082: The refresh token has expired due to inactivity". They check \`~/.azure/\`, see \`msal\_token\_cache.json\` with tokens having \`exp\` claims in the past. They try \`az account show\`, which reads local config, but any API call fails. They realize they need to re-authenticate. They run \`az login\`, complete the device flow, and the error is resolved. They later switch to \`az login --service-principal\` with client secret for automation to avoid interactive token expiry, or set up a cron job to run \`az account show\` periodically to keep the token active.

environment: Azure CLI 2.x on Linux/macOS/Windows, interactive user login \(not service principal\). · tags: azure azure-cli aadsts700082 refresh-token expired entra-id msal · source: swarm · provenance: https://learn.microsoft.com/en-us/entra/identity-platform/refresh-tokens\#refresh-token-lifetime and https://learn.microsoft.com/en-us/cli/azure/authenticate-azure-cli\#refresh-tokens
