𝐏𝐚𝐫𝐭𝐧𝐞𝐫 𝐯𝐬 𝐂𝐮𝐬𝐭𝐨𝐦𝐞𝐫:
👉 Social Federation (Apple ID) vs Workforce Federation (Okta).
👉 Different levels of compliance and security.
👉 Different business owners and processes - but maybe the same tools and applications.
👉 Different SLA.

It's about understanding your users, risk profile, and regulatory requirements to implement the RIGHT security measures for each context.
And you? Do you use similar authentication/authorization methods like on the screen?

What is the best tool to review public Entra ID Tenant data?

For me: AADInternals OSINT (site & PowerShell module)

We can get complete details about the tenant, including:
👉 Tenant ID
👉 Tenant Name (onmicrosoft domain)
👉 Domains (all domains connected with tenant)
👉 Brand name

Do you need to meet complicated password requirements?
Feel free to use a 60-character password.

I recommend a couple of components:
👉 Management API.
👉 User Flows & Customization.
👉 Entra ID as Code.
👉 Profile as a central place to manage user details.
👉 My demo application: Portal.

A friendly reminder ;)
👉 Use Fido2 keys
👉 Use software passkey with your password managers
👉 Verifiable Credentials can also be used as a passwordless method
🚀 Passwordless is easier to use than complex long password

🚀I stopped using Visio, and other tools for:

👉 Big Picture diagrams
👉 Sequence Diagrams

And moved to PlantUML, creating all diagrams as code.

And you?

🎉 pg_documentdb is open source

I created the initial version with Vinod Sridharan (an absolutely brilliant engineer) at Microsoft a few years ago and it's come a long way since.

It reimplements Mongo API with exact semantics in PostgreSQL. Already used by FerretDB!

Entra ID vs Entra External ID

👉Do you know that there are two different tenant types?
👉Do you know that there is a dedicated tenant for your customers? Were you fully separated from your organization?

Hello token friends, do you use the content of the access token as part of your application. Then be aware that Microsoft will switch to encrypted access token and this might break stuff.

Switch to id token. #EntraID

💡 With Verifiable Credentials

👉 a full authorization flow for payments (I created a Factorlabs Bank Demo to show you the Business Case 🪙

👉also authorize access (also physical access) as a security guard 🤵

Do you have any scenario with authentication and/or authorization scenarios?

My favourite 'Cost analysis' view is Group by resource with the Daily Granuariry:
- My workloads are 'stable' I don't have picks so monthly prediction can be based on a daily consumption
- Based on the diagram I can decide and move to another resource type to limit the cost of the solution

Verifiable Credentials (VC) facts and cases:
- passwordless for your Identity Provider (authentication)
- a framework used by EIDAS to authorize via National ID
- coupons, gift cards
- authorize physical access and person-people verification
- with national ID can be a captcha verification

Look at the blog post if you are thinking about the solution to speed up token enrichment with authorization data.

In my opinion many cases for 80% of calls the response is static (Pareto principal) and with a key-value store, we can deliver the response fast!

DOOM as captcha 😍

One of the methods to protect your CIAM system from synthetic (for example fake accounts with 10 min mailbox) is the captcha system.

The best one is not involving you as a user to prove you are human.

But look this one is amazing ;)
