How to Get Started with Microsoft Entra ID for Passwordless Login

This is a practical, up-to-date guide to Started — what it is, why it matters in 2026, and how to apply it in real projects. It is written for developers and founders who want clear answers and proven best practices, not filler.

Whether you're just starting out or leveling up, treat this as a working reference you can return to. Every section is built to be skimmed, applied, and shared.

Ransomware and the shift to double extortion

Ransomware has evolved from opportunistic file encryption into a professionalized criminal industry built around ransomware-as-a-service, where operators lease their malware and infrastructure to affiliates for a cut of the proceeds. The dominant tactic is now double extortion: attackers exfiltrate sensitive data before encrypting systems, then threaten to leak it publicly if the victim restores from backups instead of paying. Initial access frequently comes through phishing, stolen or purchased credentials, and unpatched internet-facing services, after which attackers escalate privilege and move laterally to reach the most valuable systems. Defenses that actually change outcomes include phishing-resistant MFA, aggressive patching of exposed services, network segmentation to blunt lateral movement, and above all immutable, offline backups whose restoration has been tested. Law enforcement takedowns of groups have disrupted the ecosystem periodically, but affiliates tend to regroup under new brands.

Threat intelligence and the MITRE ATT&CK framework

Threat intelligence is the practice of collecting, analyzing, and operationalizing information about adversaries, their infrastructure, and their techniques so defenders can anticipate and detect attacks. It spans strategic intelligence about which threat actors target your sector, operational intelligence about active campaigns, and tactical indicators of compromise like malicious domains and file hashes. The MITRE ATT&CK framework has become the common language for describing adversary behavior, cataloging tactics and techniques observed in the wild so that detections and red-team exercises can be mapped to the same taxonomy. Structured formats such as STIX and TAXII let organizations share intelligence machine-to-machine, and Information Sharing and Analysis Centers coordinate this within industries. The practical payoff is moving detection up the pyramid of pain, from brittle indicators toward the tactics, techniques, and procedures that are expensive for an adversary to change.

Supply-chain security and the software bill of materials

Software supply-chain security addresses the risk that your software is only as trustworthy as the third-party components, build systems, and update channels it depends on. The SolarWinds attack, in which adversaries compromised a build pipeline to distribute a backdoored update, and the Log4Shell vulnerability in the ubiquitous Log4j library, showed how a single upstream compromise cascades to thousands of victims. A core defensive practice is producing a software bill of materials, a machine-readable inventory of every component and version in a product, using formats like SPDX or CycloneDX so that when a new vulnerability lands, teams can instantly answer whether they are affected. Frameworks such as SLSA define levels of build integrity, and tools like Sigstore enable signing and verification of artifacts so consumers can confirm provenance. On the operational side, dependency scanning, pinning versions, and vetting the maintainers of critical open-source packages reduce the chance of pulling in a poisoned dependency.

Identity and access management as the control plane

In a zero trust world, identity becomes the primary control plane, and identity and access management is the discipline that governs it. IAM covers authentication, authorization, single sign-on, lifecycle provisioning, and increasingly the governance of who has access to what and why. Platforms such as Microsoft Entra ID, Okta, Ping Identity, and open-source options like Keycloak centralize authentication and issue tokens using protocols like SAML, OAuth 2.0, and OpenID Connect. A closely related discipline, privileged access management, wraps extra controls around high-value admin accounts, while identity governance and administration handles access reviews and certification. The hardest and most valuable work is often reducing standing privilege through just-in-time and just-enough access, so that powerful entitlements exist only for the moments they are actually needed.

Passwordless authentication and why passwords fail

Passwords are the root cause of a large fraction of breaches because they are reused, phishable, and harvestable at scale from breach dumps. Passwordless authentication removes the shared secret entirely, replacing it with something the user possesses (a device with a private key) combined with a local biometric or PIN that never leaves that device. The dominant standard here is FIDO2, and the most visible consumer manifestation is the passkey. Because the authentication is based on public-key cryptography and is bound to the specific website origin, there is no reusable secret for an attacker to steal, and credential-stuffing and phishing attacks that plague password systems simply do not work. Enterprises typically roll this out alongside identity providers like Microsoft Entra ID, Okta, or Google Workspace, which now support passwordless sign-in flows natively.

SASE: converging networking and security in the cloud

Secure Access Service Edge, a term coined by Gartner in 2019, describes the convergence of wide-area networking and network security functions into a single cloud-delivered service. A SASE platform typically bundles SD-WAN with security service edge components including a secure web gateway, cloud access security broker, firewall-as-a-service, and zero trust network access. The value proposition is that a remote or branch user connects to the nearest cloud point of presence, where policy is applied once, instead of backhauling all traffic to a datacenter firewall. Vendors such as Zscaler, Palo Alto Networks with Prisma Access, Cloudflare, Netskope, and Cato Networks compete in this space. Many organizations are consolidating previously separate point products onto a single-vendor SASE fabric to reduce complexity and close the seams between networking and security policy.

Started: Key Facts and Data

According to recent industry research and the official documentation linked below:

• Analyst firms such as Gartner have projected that a large share of new SASE and zero trust network access purchases are consolidating onto single-vendor SASE platforms rather than assembling point products.
• Supply-chain attacks such as SolarWinds (2020) and the Log4Shell vulnerability in Apache Log4j (2021) demonstrated how a single compromised dependency or build system can cascade to tens of thousands of downstream organizations.
• CISA and NIST guidance increasingly treats a software bill of materials (SBOM) as a baseline expectation, and US federal procurement rules have pushed SBOM generation into mainstream enterprise software delivery.

How to Get Started with Started

A simple path that works:

1. Learn the fundamentals of Started from primary sources, not just tutorials.
2. Build one small, real project end to end.
3. Get feedback, refactor, and add tests.
4. Ship it publicly and document what you learned.
5. Repeat with a slightly harder project each time.
