Hey all! Passkeys are quickly becoming the future of authentication in M365. Outside of general security, they can help a ton with securing AI workloads and the more sophisticated attacks we are seeing with AI today. I put together a full course you can check out in the classroom: Full Course - Passkeys · Tminus365 In this classroom section, I also include a full troubleshooting guide for helpdesk along with end-user self-service guides depending on the passkey types you want to support. How many of you are rolling out passkeys today?

Hey all, I recently published a new video outlining the recent CW breach where I recreated the attack chain live in a tenant. The big takeaway is that this could happen with any app you've granted access to in your M365 environment so don't think this doesn't apply to you if you don't leverage CW/Skykick. I made some resources you all can leverage to: 1. Protectively protect you tenant from these attacks 2. An IR plan you can activate if this every happens with a vendor you have in tenants in the future. You can find the resources here: CW Breach Resources - Secure Application Management · Tminus365 Any of you impacted by this event?
