Authenticating users in tools or desktop appsIf your plan is to develop a tool or desktop app instead of a server-side application, the benefits of application default credentials are less obvious and reusing the user’s personal gcloud credentials instead might seem attractive. But there are some pitfalls. Continue »
Application default credentials vs your personal gcloud credentialsgcloud manages two sets of credentials, your personal credentials and application default credentials. Having two separate credentials might seem redundant and can cause surprises the first time you use one of the Google Cloud client libraries. But the two credentials serve different purposes.

Installing Remote Desktop Connection Manager as limited userInstalling the Remote Desktop Connection Manager requires administrator privileges. That can be a problem in a corporate environment where you might not have local administrator rights. Fortunately, there is an easy way to overcome this limitation by performing an administrative installation. Continue »
Dealing with credentials when using the Google Cloud client libraries (.NET edition)Google APIs use OAuth 2.0 for authentication and authorization. To call an API, you first have to obtain an access token for the right scope and then pass it to the respective API by using the Authorization HTTP header.
But the trouble with access tokens is that they are short-lived, and you somehow have to deal with expiring tokens…

Impact of GCP session length on OAuth clientsOnce you’ve signed in on google.com, the Cloud Console, or any other Google site, your browser session remains valid for multiple days. Not being prompted to sign in over and over again is convenient and at least in typical consumer scenarios, the risk that comes along with keeping the session is limited.
Things can look different in a corporate scenario where users might have access to sensitive data. Keeping sessions alive for 14 days (which is the default) might seem a little risky and might not be in line with an enterprise’s idea of security. G Suite Business and Cloud Identity Premium therefore allow you to change the default session length to a different period such as 8 hours. This setting applies to all Google services, not only GCP.
Recently, Google introduced another way to control session lifetime by allowing you to control the session length for Cloud Console and gcloud sessions.

New version of the Cloud IAP plugin for Remote Desktop releasedA few days ago, I released version 1.1.22 of the Cloud IAP plugin for Remote Desktop on Github.
The three main new features in this release are:
Integrating with Cloud IAPIn the last post, we discussed that each request that Cloud IAP passes to a backend appliation contains a X-Goog-Iap-Jwt-Assertion header. This header contains an IAP JWT assertion that looks a bit like an IdToken, but is not an IdToken.

Cloud IAP architectureConceptually, you can think of Cloud IAP as a reverse proxy that is deployed in front of your corporate application that intercepts all requests to perform authentication and authorization. Continue »
Cloud IAP and its role in zero-trustAt Google Cloud, we run a series of Cloud Summits each year. A Cloud Summit is essentially a mini-version of Cloud NEXT – it lasts one day, features multiple tracks of technical sessions, and is usually held in a location where there is plenty of space for booths where customers can ask questions.
One question that we frequently get at the Ask an Architect or Ask the Expert booth is about Cloud Identity-Aware Proxy - what is it for, how does it work, and how to use it?
In this series of blog posts, I am going to address these questions, one at a time:
