Between certain staff (e.g., accountant -> CFO), it may make sense to share a secret passphrase to authenticate each other. If you want to get fancy, share a TOTP seed to reduce the risk further.

After a few months of catching up on AI - I have condensed some thoughts on LLMs into a presentation called "Demystifying LLMS and Threats" : youtube.com/watch?v=q_gDtO… and I hate just video material so I also turned it into a VERY long post here: medium.com/csima/demystif…

At @RobinhoodApp we believe the best way to help keep our customers safe is to combine security with a great user experience. That is why we are proud to be one of the first to support Apple's Passkey feature - a step towards a passwordless world.

Something unique and thought provoking but also extreme with no grey. That way it generates debate and discussion with no practical outcome

This is the best security tool released in probably 10 years. Maybe longer. It’s Nessus—except transparent and automatable—and for AppSec as well.
