The Future of Business Authentication

The reliance on long and complex passwords, combined with the common practice of reusing them across multiple services, exposes companies to critical risks, from phishing attacks to massive credential theft. Today, the business environment is moving toward an era without passwords. By adopting passkeys within the Microsoft ecosystem, companies have the opportunity to minimize the risks of cyberattacks and transform the way their employees access corporate resources.

Passwords have been the Achilles' heel of cybersecurity for decades. Companies face daily phishing attacks that compromise credentials, with Microsoft reporting more than 7,000 blocks per second in 2025. This creates not only costly data breaches, but also an operational burden: employees waste time resetting passwords and IT teams handle endless tickets.

‍

What Are Passkeys?

Passkeys are unique cryptographic credentials stored on the user's device, authenticated using biometrics such as fingerprint or facial recognition, without transmitting sensitive data to servers. Unlike passwords, passkeys are resistant to phishing because they can't be reused or intercepted; each one is unique to each account and device. Microsoft has positioned them as default for new accounts since 2025, with a cloud synchronization process that ensures multi-device access without security compromises.

Key Benefits for Companies

Adopting passkeys with Microsoft offers tangible benefits that go beyond basic security.

‍

Improved user experience: Logins are up to eight times faster and with a 98% success rate.

Compliance and Scalability: They facilitate compliance with regulations such as GDPR or NIST by eliminating common attack vectors, and they easily scale in hybrid environments with Entra ID for thousands of users.

Reinforced privacy: Biometry is processed locally on the device, never shared, protecting sensitive data in a world of BYOD and remote work.

The Phishing Attack That Almost Sinked a Fintech

In March 2025, a FinNova Tech employee received a phishing email disguised as an “Azure security update” — a spear phishing that mentioned company details obtained from LinkedIn. The email includes a link to a fake site that simulates the Microsoft portal, asking for credentials to “verify the account”. The employee, under pressure, enters their username and password, activating an infostealer (malware that steals credentials from browsers and apps).

Attackers instantly gain access to the employee's Entra ID account, who had administrative permissions.

The Solution: Combining Microsoft Services to Prevent Credential Attacks

To mitigate the risks of phishing, credential theft, and infostealers in business environments, we recommend a Zero Trust approach that integrates multiple Microsoft services. This multilayered strategy prevents initial theft, detects anomalies in real time, and strengthens human resilience.

‍

Passkeys as a basis for strong authentication.

Conditional Access for contextual control.

Detecting Risky Users

Privileged Identity Management (PIM)

Anti-phishing training with Microsoft tools (Attack simulation)

Holistic integration and continuous monitoring

‍

This combination of services creates a layered defense: passkeys prevent initial theft, Conditional Access and risky users detect/mitigate it, and training prevents recurrences.

Conclusion

Don't wait for a security breach to define the course of your company. Adopting passkeys doesn't just transform business authentication, it establishes a new line of defense for your data and reputation. In an environment where protection is key to competing and growing, Microsoft provides a solid ecosystem that allows organizations to anticipate risks and move towards a future without passwords, where security is an integral part of business strategy.
