I watched one misconfigured service take down an entire platform because everything shared the same resource pools. Here is the bulkhead pattern that prevents it, with a working .NET 8 demo you can run locally in minutes.
A passkey registered on bank.com will not activate on bank-secure-login.com. The cryptography enforces the boundary without asking the user to spot the fake.
