Expert Tip
Adaptive authentication represents the next evolutionary step beyond traditional MFA. With this approach, authentication factors are dynamically required based on the risk context of a login – such as location, time of day, device used, or user behavior patterns. Higher risks trigger stricter authentication requirements, while lower-risk scenarios enable simplified authentication. This intelligent balance between security and user-friendliness leads to significantly higher acceptance and satisfaction among users. Start with a solid risk assessment of your various applications and user groups to develop a tiered MFA concept that provides optimal protection with minimal user burden.

Our approach to MFA projects is based on proven methods and best practices that we adapt to your specific requirements and circumstances. We combine security expertise with a focus on user-friendliness to develop a solution that provides both optimal protection and high acceptance.
Our Approach:
Phase 1: Requirements Analysis and Inventory - Determination of security requirements and compliance specifications, analysis of existing authentication mechanisms, identification of applications and resources requiring protection, capture of user groups and their requirements, assessment of IT infrastructure and existing IAM components, definition of success criteria and KPIs
Phase 2: Strategy Development and Solution Design - Development of an MFA strategy and roadmap, selection of suitable MFA methods and technologies, design of a risk-based authentication architecture, conception of exception processes and fallback mechanisms, definition of roles and responsibilities, creation of an implementation plan
Phase 3: Implementation and Integration - Setup of MFA infrastructure, integration into existing identity providers and directory services, configuration of authentication policies and rules, connection of relevant applications and resources, implementation of monitoring and reporting, execution of security tests
Phase 4: Rollout and Adoption - Development of a communication and training strategy, execution of pilot projects with selected user groups, collection and integration of feedback, phased expansion to additional user groups, provision of support and help materials, accompanying change management
Phase 5: Operations and Continuous Improvement - Handover to regular operations, establishment of support and maintenance processes, regular review and adjustment of authentication policies, monitoring of MFA usage and effectiveness, integration of new authentication methods, continuous improvement based on user feedback
"In our MFA projects, we consistently observe that success depends significantly on user acceptance. Even the most secure solution will fail if users perceive it as too cumbersome. Therefore, we recommend involving all relevant stakeholders early and considering different user groups. Careful planning of the rollout with targeted communication and training measures is crucial. A phased approach has proven particularly effective: Start with less critical applications, gather experience and feedback, and then gradually expand MFA usage to more critical systems. This allows you to continuously optimize the process and increase acceptance."

Frequently Asked Questions about Multi-Factor Authentication (MFA)
What is Multi-Factor Authentication (MFA) and how does it work?
Multi-Factor Authentication (MFA) is a security mechanism that requires users to verify their identity through multiple independent factors before gaining access to a system or application. It combines at least two of the following authentication factors:
•
**Knowledge factor
** (something you know): Password, PIN, security question
•
**Possession factor
** (something you have): Smartphone, hardware token, smart card
•
**Inherence factor
** (something you are): Fingerprint, facial recognition, iris scanThe process works as follows: After entering the first factor (typically a password), the user must provide a second factor – for example, a one-time code from an authenticator app or a biometric scan. Only when both factors are successfully verified is access granted. This significantly increases security, as an attacker would need to compromise multiple independent factors to gain unauthorized access.
What benefits does MFA offer for companies?
Multi-Factor Authentication provides companies with numerous security and business benefits:**Security benefits:**
•
**Protection against password theft**: Even if passwords are compromised, access remains blocked without the second factor
•
**Phishing defense**: MFA methods like FIDO 2 are resistant to phishing attacks
•
**Reduced risk of data breaches**: Significantly lower probability of unauthorized access to sensitive data
•
**Protection of privileged accounts**: Particularly important for administrator and system accounts**Compliance and business benefits:**
•
**Regulatory compliance**: Fulfillment of requirements from GDPR, PCI DSS, ISO 27001, NIST 800‑63, NIS2• **Cyber insurance**: Many insurers require MFA as a prerequisite for coverage
•
**Customer trust**: Demonstrable commitment to data protection and security
•
**Cost reduction**: Fewer security incidents and associated costs
•
**Flexibility**: Support for remote work and BYOD strategies without compromising securityStudies show that MFA can prevent over 99% of automated attacks on user accounts.
What are the main MFA methods and their respective advantages and disadvantages?
There are various MFA methods, each with specific characteristics:**1. Authenticator Apps (TOTP/HOTP)**
•
Advantages: No additional hardware required, works offline, high security
•
Disadvantages: Requires smartphone, initial setup necessary

What role does MFA play in the context of Zero-Trust security?
Multi-Factor Authentication is a fundamental pillar of the Zero-Trust security model:**Core Principle of Zero-Trust:**"Never trust, always verify" – No user or device is automatically trusted, regardless of whether they are inside or outside the network perimeter.**MFA as a Zero-Trust Component:****1. Strong Identity Verification**
•
MFA ensures that users are who they claim to be
•
Goes beyond simple password verification
•
Foundation for all subsequent access decisions**2. Continuous Authentication**
•
In Zero-Trust, authentication is not a one-time event
•
MFA can be combined with risk-based authentication
•
Re-authentication required for sensitive actions**3. Least Privilege Access**
•
MFA enables granular access controls
•
Different MFA requirements for different security levels
•
Privileged access requires stronger authentication**4. Integration with Other Zero-Trust Elements:**
•
**Device Trust**: MFA combined with device compliance checks
•
**Context-Based Access**: Consideration of location, time, risk score
•
**Micro-Segmentation**: MFA for access to individual network segments
•
**Continuous Monitoring**: MFA events as part of security monitoring**Practical Implementation:**
•
Adaptive MFA: Stronger authentication required for unusual access patterns
•
Passwordless authentication: Combination of biometrics and FIDO2• Integration with Identity and Access Management (IAM) platforms
•
Automated policy enforcement based on risk assessmentWithout robust MFA, a Zero-Trust architecture cannot be effectively implemented, as identity verification is the foundation for all access decisions.
What is adaptive authentication and how does it work?
Adaptive authentication, also known as risk-based authentication, is an intelligent MFA approach that dynamically adjusts authentication requirements based on the risk level of an access attempt:**How it works:****1. Risk Assessment**The system analyzes various factors in real-time:
•
**User behavior**: Typical login times, usual locations, device usage
•
**Context information**: IP address, geolocation, network type
•
**Device characteristics**: Known/unknown device, security status, compliance
•
**Access patterns**: Accessed resources, unusual activities
•
**Threat intelligence**: Known malicious IP addresses, current attack patterns**2. Dynamic Authentication Decision**
•
**Low risk**: Simple authentication (e.g., password only)
•
**Medium risk**: Standard MFA (password + authenticator app)
•
**High risk**: Strong MFA (password + hardware key) or access denial
•
**Very high risk**: Additional verification steps or temporary blocking**3. Continuous Evaluation**
•
Risk assessment not only at login but throughout the session
•
Step-up authentication for sensitive actions
•
Automatic logout upon significant risk changes**Practical Examples:**
•
Login from the usual office location with a known device → Password only
•
Login from a new location → Additional MFA required
•
Login from a foreign country at unusual times → Strong MFA + additional verification
•
Access to particularly sensitive data → Always requires MFA, regardless of context**Benefits:**
•
Balance between security and user-friendliness
•
Reduction of "MFA fatigue" for routine accesses
•
Automatic response to anomalies
•
Compliance with regulatory requirements for risk-based access controlsModern IAM platforms like Microsoft Entra ID (Azure AD), Okta, and Ping Identity offer built-in adaptive authentication capabilities.

Improves user experience and reduces password fatigue**Multi-Factor Authentication (MFA):**
•
Requires multiple factors to verify user identity
•
Significantly increases security
•
Protects against password compromise**2. How MFA and SSO Work Together****Optimal User Flow:**1. User accesses application2. Redirected to SSO portal (IdP)3. Enters username and password (Factor 1)4. Prompted for MFA (Factor 2: app, biometric, key)5. Upon successful MFA: SSO session established6. Access granted to all authorized applications7. No additional authentication needed during session**Benefits:**
•
Security: Strong authentication at entry point
•
Convenience: Authenticate once, access many applications
•
Reduced MFA fatigue: MFA only at SSO level

Automatic logout on inactivity**MFA Re-Authentication:**
•
Remember device: 30‑90 days for trusted devices
•
Step-up authentication: MFA for sensitive actions
•
Risk-based: Re-authenticate on risk change**6. Conditional Access Policies****Context-Based Requirements:**
•
Inside corporate network: SSO only
•
Outside network: SSO + MFA
•
Privileged users: Always require MFA
•
Sensitive applications: Always require MFA
•
Non-compliant devices: Limited access or blocked**7. Security Considerations****SSO as Single Point:**
•
Risk: Compromised SSO = access to all applications
•
Mitigation: Strong MFA at SSO level, continuous monitoring, anomaly detection**Defense in Depth:**
•
MFA at SSO level (primary)
•
Additional MFA for critical applications (secondary)
•
Network segmentation
•
Least privilege access**8. User Experience Optimization****Reducing MFA Prompts:**
•
Trusted devices: Remember MFA for known devices
•
SSO session: Single MFA for multiple apps
•
Adaptive authentication: MFA only when risk increases**Seamless Authentication:**
•
Windows Hello for Business: Biometric SSO + MFA
•
FIDO 2 security keys: Passwordless SSO + MFA
