Best passwordless authentication solutions for 2026
The uncomfortable truth is this: Passwords are still the weakest link in identity security, even when layered with traditional MFA.
This is why organizations are actively replacing passwords with passwordless authentication solutions.
Passwordless authentication solutions aim to reduce reliance on passwords by using device-bound and cryptographic factors to verify user identity.
But not all passwordless solutions offer the same level of protection. Choosing the right one depends on how its authentication works under the hood and adapts to real-world risk.
Top passwordless authentication solutions in 2026
ADSelfService Plus
Strengths
Diverse authenticator support
ADSelfService Plus supports multiple passwordless methods, including FIDO2 authentication, passkeys, biometrics, push notifications, and one-time passwords, enabling organizations to eliminate passwords without enforcing a single model.
Passwordless SSO for enterprise applications
Enables password-free access to 100+ pre-integrated enterprise and custom applications, allowing users to authenticate securely without entering passwords all while maintaining compatibility with existing infrastructure.
Adaptive MFA
Adaptive MFA ensures passwordless access remains secure across varying risk scenarios without relying on static, one-size-fits-all policies.
Comprehensive passwordless multi-factor authentication with ecosystem integrations
Supports a wide range of authenticators, making it easier to align authentication strength with user roles, security requirements, and operational constraints. It also integrates with ITSM, SIEM, and IAM tools such as ServiceDesk Plus, Splunk, and AD360, extending passwordless access, MFA, and SSO across broader IT and security workflows.
Self-service enrollment
Self-service enrollment simplifies passwordless adoption at scale by reducing IT dependency while maintaining control over approved authenticators. With support for a wide range of authenticators, users can enroll devices and methods that suit their needs, reducing IT overhead while ensuring passwordless access is securely integrated across the organization.
Scalable across workforce and enterprise use cases
ADSelfService Plus supports passwordless MFA across a wide range of workforce scenarios, including enterprise applications, Outlook on the web access, and self-service portals. This makes it suitable for organizations with diverse user groups, roles, and access requirements to scale password-free authentication consistently across the entire enterprise.
Visibility and reporting
ADSelfService Plus provides detailed reports on authenticator enrollment and usage, enabling administrators to analyze how different passwordless methods are adopted across the organization. These insights help teams fine-tune authentication policies, phase rollouts, and strengthen security based on real-world usage patterns rather than assumptions.

Best practices for configuring passwordless authentication flows
Use phishing-resistant methods for high-impact roles
Protect admins, executives, and privileged users with passkeys or FIDO2 security keys that can’t be phished or replayed.
Apply adaptive authentication
Let authentication strength change dynamically based on device trust, location, behavior, and access context.
Keep fallback methods controlled and auditable
Fallback options should exist for recovery, but they must be tightly governed, monitored, and never a default path.
Don’t layer passwordless on top of passwords
Passwordless authentication should replace passwords, not remain as a cosmetic step following weak credentials.
Monitor authentication patterns continuously
Track failures, unusual logins, and risky behavior to spot gaps before attackers exploit them.
How organizations use passwordless authentication today
In practice, most organizations use a mix of methods:
Passkeys for daily workforce access
Biometrics for frictionless logins
Hardware keys for privileged users
Push verifications or TOTPs for controlled fallback options
This layered approach balances usability and risk.
