How Europe’s Banks Are Ditching Passwords in 2025

The days of frantically typing "Password123!" into your banking app are numbered. As we move through 2025, European financial institutions are rapidly abandoning traditional password systems in favour of more secure, user-friendly alternatives. This shift isn't just about convenience; it's driven by regulatory pressure, security concerns, and changing customer expectations.

The European Banking Authority reported that password-related security incidents cost EU banks over €2.8 billion in 2024 alone. Meanwhile, passwordless authentication methods are showing remarkable success rates, with some banks reporting 40% fewer security breaches and 60% faster login times.

This transformation is reshaping how millions of Europeans access their financial services daily. From biometric authentication to hardware tokens, the future of banking security is already here—and it's surprisingly simple to use.

The End of Passwords: What FIDO Enables

The Fast Identity Online (FIDO) Alliance has become the backbone of passwordless banking across Europe. This open standard allows banks to implement authentication methods that are both more secure and more convenient than traditional passwords.

FIDO works by creating a unique cryptographic key pair for each user account. The private key stays securely on your device whether that's your smartphone, laptop, or a dedicated hardware token while the bank stores the public key. When you want to access your account, your device proves it has the private key without ever transmitting it.

How FIDO Changes Your Banking Experience

Instead of remembering complex passwords, you'll authenticate using:

• Biometrics: Your fingerprint, face, or voice becomes your password. Most modern smartphones already support these methods, making the transition seamless for customers.
• Hardware Tokens: Small USB devices or smart cards that generate unique codes. Popular in Germany and the Netherlands, these provide an extra layer of security for high-value transactions.
• Device-Based Authentication: Your smartphone or computer becomes a trusted authenticator, using built-in security features to verify your identity.

The beauty of FIDO lies in its flexibility. Banks can offer multiple authentication options, allowing customers to choose what works best for their lifestyle and security preferences.

European banks implementing FIDO have seen impressive results. 

ING reported a 45% reduction in customer support calls related to login issues, while Santander noted that 78% of their customers prefer biometric authentication over passwords.

Regulatory Mandates You Can't Ignore

European regulators are actively pushing banks towards passwordless systems. The revised Payment Services Directive (PSD2) requires strong customer authentication for most electronic payments, whilst the Digital Operational Resilience Act (DORA) emphasises robust security measures.

PSD2 and Strong Customer Authentication

PSD2 mandates that banks implement strong customer authentication (SCA) for payments above €30 and certain account access scenarios. This requires at least two of the following elements:

• Something you know (knowledge)
• Something you have (possession)
• Something you are (inherent)

Traditional passwords only satisfy the "knowledge" requirement, forcing banks to implement additional security layers. Passwordless systems naturally fulfil multiple requirements, making compliance more straightforward.

DORA's Impact on Banking Security

The Digital Operational Resilience Act, fully applicable since January 2025, requires financial institutions to have robust operational resilience frameworks. This includes implementing authentication systems that can withstand cyber attacks and operational disruptions.

Passwordless systems align perfectly with DORA requirements. They reduce the attack surface by eliminating password databases and provide better audit trails for regulatory reporting.

The European Central Bank's latest guidance specifically mentions passwordless authentication as a preferred method for meeting regulatory requirements. This regulatory backing is accelerating adoption across the continent.

Identity Assurance in Finance Explained

Identity assurance in banking goes beyond simple authentication; it's about continuously verifying that users are who they claim to be throughout their banking session. This concept becomes crucial as financial services become increasingly digital and sophisticated.

The Three Pillars of Identity Assurance

1. Verification: Confirming a user's identity during account creation using official documents, biometric data, and sometimes in-person verification.
2. Authentication: Proving that the person accessing the account is the legitimate account holder through passwordless methods like biometrics or hardware tokens.
3. Continuous Monitoring: Analysing user behaviour patterns, device characteristics, and transaction contexts to detect anomalies that might indicate fraud.

Risk-Based Authentication

Modern banking platforms use risk-based authentication to balance security with user experience. The system analyses various factors:

• Device recognition and location
• Transaction patterns and amounts
• Time of access and frequency
• Network characteristics

Low-risk scenarios only require a fingerprint, whilst high-risk transactions could demand multiple authentication factors. This approach reduces friction for routine banking whilst maintaining security for sensitive operations.

Privacy by Design

European banks must comply with GDPR whilst implementing these systems. Passwordless authentication enhances privacy by reducing the amount of sensitive data stored centrally. Biometric templates and private keys remain on user devices, limiting data exposure.

The principle of data minimisation aligns perfectly with passwordless systems. Banks only store what they need the public key whilst all sensitive authentication data stays with the user.

Case Study: Passwordless Success in Banking

Several European banks have successfully implemented passwordless systems, providing valuable insights into real-world performance and customer adoption.

Nordea's Biometric Revolution

Nordea, one of Northern Europe's largest banks, implemented comprehensive biometric authentication across all its digital channels in 2024. The results have been remarkable:

• 52% reduction in login-related customer complaints
• 38% faster average login times
• 91% customer satisfaction rate with biometric authentication
• 65% decrease in account takeover attempts

The bank's approach focused on a gradual rollout, starting with mobile applications before expanding to web platforms. They provided extensive customer education, including video tutorials and in-branch demonstrations.

Deutsche Bank's Hardware Token Integration

Deutsche Bank took a different approach, emphasising hardware-based authentication for its premium customers. Their programme included:

• FIDO2-compliant USB security keys for high-net-worth individuals
• Smartphone-based authentication for standard customers
• Hybrid options allow customers to choose their preferred method

The bank reported that 84% of customers using hardware tokens felt more confident about their account security, whilst transaction fraud decreased by 43% among this group.

Lessons from Implementation

These case studies reveal several key success factors:

• Customer Education: Banks that invested in comprehensive education programmes saw faster adoption rates and fewer support issues.
• Gradual Rollout: Phased implementations allowed banks to identify and resolve issues before full-scale deployment.
• Multiple Options: Offering various authentication methods accommodates different customer preferences and technical capabilities.
• Fallback Mechanisms: Maintaining temporary backup authentication methods ensured service continuity during the transition period.

The Road Ahead for European Banking

The shift to passwordless banking represents more than a technological upgrade—it's a fundamental reimagining of how financial institutions interact with their customers. As we progress through 2025, this transformation will accelerate, driven by regulatory requirements, security concerns, and customer expectations.

European banks are well-positioned to lead this global change. The combination of strong regulatory frameworks, technological innovation, and customer-centric approaches creates an ideal environment for passwordless adoption.

The evidence is clear: passwordless authentication improves security, enhances user experience, and reduces operational costs. For European banks, the question isn't whether to adopt these technologies, but how quickly they can implement them effectively.

As this revolution unfolds, customers can expect more secure, convenient, and privacy-respecting banking experiences. The future of financial services is passwordless and it's arriving faster than many anticipated.
