terruahmad 

To mask the Azure App Insights connection string in Azure DevOps:

Use Secret Variable: Add it as a secret variable in your pipeline settings (APP_INSIGHTS_CONN_STRING). It will be masked in logs.

- script: |
    export APP_INSIGHTS_CONN_STRING=$(APP_INSIGHTS_CONN_STRING)
  displayName: "Setup App Insights Connection String"

Use Azure Key Vault: Store it in Azure Key Vault, then retrieve it in your pipeline with the Azure Key Vault task. The secret will stay masked.
- task: AzureKeyVault@1
  inputs:
    azureSubscription: '<Your Service Connection>'
    keyVaultName: '<Your Key Vault Name>'
    secretsFilter: 'APP_INSIGHTS_CONN_STRING'

Both methods will securely mask the connection string in pipeline logs
