Introduction

Microsoft Entra ID, formerly known as Azure Active Directory, has introduced a significant enhancement to its authentication toolkit by enabling Temporary Access Passes (TAPs) for internal guest users. This marks a notable development in the realm of identity and access management, specifically improving secure, temporary credential issuance to internal guests within organizations.

Background on Microsoft Entra ID and Temporary Access Passes

Microsoft Entra ID is a unified cloud identity solution designed to manage and secure access to enterprise resources. It supports advanced authentication mechanisms including passwordless authentication to strengthen security and streamline user experience.

Temporary Access Passes are time-limited, one-time codes used to securely onboard or recover accounts without requiring passwords. Previously, TAPs were primarily available to full members within an organization; extending this functionality to internal guests now allows organizations to securely grant temporary, controlled access to users who are not full members but require access to sensitive resources.

What’s New: TAPs for Internal Guests

The new capability specifically targets internal guest users — such as contractors, temporary workers, or partners — who access enterprise systems but do not hold permanent full member credentials. With the introduction of TAP support for these users, IT administrators can now:

  • Issue Temporary Access Passes that provide ephemeral access aligned to organizational policies.
  • Enhance security posture by reducing dependency on persistent passwords or long-term access tokens that could be vulnerable if compromised.
  • Simplify the user experience by enabling quick onboarding or recovery without exposing permanent credentials.

Technical Details

  • Scope: TAPs can be provisioned for internal guest accounts within the Entra ID tenant.
  • Duration: The passes are valid for a configurable timespan, ensuring access automatically expires.
  • Use Cases: Ideal for onboarding, password resets, or emergency access scenarios without compromising security.
  • Integration: TAPs work seamlessly with Microsoft Authenticator and other multi-factor authentication mechanisms, supporting passwordless strategies.

Implications and Impact

This update reflects a broader shift towards zero trust security principles where access is granted dynamically based on verified identity and least privilege.

  1. Enhanced Security: By limiting access duration and scope, organizations minimize risk exposure from long-lived credentials.
  2. Operational Efficiency: IT teams can reduce support calls for password resets and streamline guest user onboarding.
  3. Passwordless Momentum: TAPs fit directly into Microsoft’s push for passwordless environments, reducing reliance on traditional password management.

Organizations leveraging Microsoft Entra ID will find this feature particularly valuable for maintaining a fine-grained, auditable access control regime.

Broader Context

This feature complements other recent Microsoft security advancements, such as device-bound passkeys via Microsoft Authenticator and risk-based Conditional Access policies, which collectively strengthen defense against phishing and credential theft. For example, government agencies have used TAPs combined with device-bound passkeys to bolster the security of privileged accounts, achieving both speed and phishing resistance in authentication workflows.

Conclusion

Microsoft Entra ID’s support for Temporary Access Passes for internal guests is a strategically important update that enhances secure, flexible authentication options. It empowers IT administrators to manage guest access securely while aligning with modern passwordless and zero trust security frameworks. As organizations increasingly rely on guest and partner collaboration, this capability will help bridge usability and security effectively.
