**Location:** ETH Zürich, near Polyterrasse (Universitätstrasse 6, Building CNB, Room F100.9) **Event Topic:** One of OpenClaw's great strengths is its direct command-line access to user space—this flexibility enables rapid development of automation workflows without the friction of rigid APIs or sandboxed environments. But by default, this means the agent has plaintext access to all connected service credentials, whether Gmail, Calendar, WhatsApp, or others. This creates a broad attack surface and limits our ability to enforce fine-grained access policies. In this meetup, we'll explore a practical architecture for credential isolation using macOS user spaces. We'll walk through how to deploy separate service proxies, each running in its own user context, to isolate credentials per service. These proxies act as gateways between the OpenClaw agent and your accounts, enabling you to implement arbitrary access policies—rate limiting, scope restrictions, audit logging, or whatever your threat model requires. The good news: this architecture is simple enough to vibecode. You don't need deep systems expertise to get started—we'll show you how to scaffold the setup quickly and iterate from there. Whether you're running OpenClaw for personal automation or exploring agent deployments in more sensitive contexts, this session will give you hands-on techniques for tightening your security posture without sacrificing the rapid iteration that makes OpenClaw powerful.

I'm really excited to announce our next Meet Up event. It will take place at Core studio in Rennweg Rennweg 12, 8001 Zurich. The is dedicated to everyone who likes the idea of exercising with the music, dancing and learning a bit of ballet. Find out how to set up the a great posture, learn about body conditioning as well as mind & body connection. Unlike at most general adult ballet classes we will show you how exercise with the precision and focus, getting great results. A great class for those that are just starting with ballet, or those who are conscious about using their body precisely and targeting correct muscle groups in order to achieve greater results. The class is structured as a unique combination of ballet exercises, Pilates, stretching and motivation. Open to all levels. You will need to bring a smile, some water and wear comfortable exercise cloths. The class will be 60 minutes which should be more than enough to get those muscles warmed up and you posturised ready for the next session. There's a small cost to cover the venue and facilities - CHF 40.- For more details about the training provider please see: https://www.balletbodysculpture.com/ballet-body-sculpture-classes-in-zurich
