Top user authentication trends for 2025

Top user authentication trends for 2025

The world of user authentication is evolving rapidly, driven by technological advancements, regulatory shifts, and the growing sophistication of cyber threats. As we step into 2025, several key trends are set to shape the way individuals and organizations verify identity, secure transactions, and protect against fraud. In this blog, we’ll cover the latest insights and strategies your organization can deploy to stay ahead of the curve. 

Identity proofing becomes routine 

Identity proofing is the process of verifying that a person is who they claim to be when accessing sensitive systems or information, particularly in banking and fintech. It typically involves validating personal information through various means, such as document verification (using passports or driver's licenses), biometric data (fingerprints or facial recognition), and other identity-verification methods (like knowledge-based authentication). 

In the future, we’ll see identity orchestration platforms integrating multiple proofing signals, including device intelligence and behavioral biometrics, making identity verification more reliable. As more services shift online, organizations need reliable methods to confirm identities in a virtual environment securely. Identity proofing can help bridge the gap between physical identity verification and digital access. Governments are likely to introduce a mix of privacy-focused regulations governing identity proofing to safeguard personal data and maintain the integrity of digital transactions and services

Fraud detection of deepfakes and synthetic identities

In 2025, the challenge of combating AI-generated deepfakes and synthetic identities will demand sophisticated fraud detection strategies. Organizations will increasingly adopt AI-powered fraud detection mechanisms to identify deepfake inconsistencies and reinforce them with biometric verification like facial recognition and voice analysis. Advanced algorithms and machine learning will process large datasets to spot patterns indicative of synthetic identities.

While AI plays a pivotal role, human oversight is still essential to prevent false positives. Regulatory bodies are expected to establish stringent guidelines addressing AI-generated fraud and emphasize identity-proofing protocols. Public education campaigns will raise awareness about digital deception risks and promote vigilance. We also expect more collaboration between businesses, governments, and cybersecurity to defend against these emerging threats.

A shift to adaptive authentication

Identity and Access Management (IAM) is undergoing a transformation, with zero trust models becoming the standard for enterprise security. Organizations are shifting to adaptive authentication strategies that assess risk in real-time and leverage AI and behavioral analytics to dynamically adjust access controls based on observed activities. The rise of passwordless authentication, driven by passkeys, biometrics, and OTP-based authentication, will further enhance security while improving user experience. 

Passkeys gain traction

Passkeys are steadily gaining traction as a user-friendly and secure authentication method. Passkeys present an appealing replacement for passwords with their integration of biometrics and PINs, but they should be viewed as an integral element of a layered authentication strategy.

Passkeys are not replacing SMS OTPs–these technologies complement rather than compete with each other. SMS OTPs continue to be indispensable, especially in scenarios where passkeys may not be practical or preferred by users. By offering different authentication options, businesses create security solutions that fit a wide range of user preferences and keep systems strong. Using passkeys alongside familiar methods like SMS OTPs provides a flexible and reliable way to keep users safe in today's complex digital world. 

Identity in payments increases security 

The financial industry continues to balance strong authentication with frictionless customer experiences. Going forward, behavioral biometrics will play a larger role in transaction authentication, helping  reduce fraud while maintaining user convenience. Strong customer authentication (SCA) regulations are expected to expand across more jurisdictions, reinforcing the need for AI-powered fraud detection that uses identity signals to predict and prevent fraudulent transactions. Meanwhile, synthetic identity fraud and account takeovers (ATOs) will become more sophisticated, requiring new detection mechanisms to mitigate risks.The need for innovation in verification will never end!

Governments and enterprises push digital IDs

Governments and enterprises alike are accelerating the adoption of digital IDs, from mobile driver’s licenses to national electronic IDs. These digital credentials are expected to gain wider acceptance in sectors such as travel, banking, and healthcare, enabling secure and efficient identity verification. For example, the United States Transportation Security Administration (TSA) allows travellers to use digital IDs from their Apple, Google, or Samsung Wallets to verify their identity at checkpoints, as long as their state is participating. Countries will continue to roll out digital identity wallets, further integrating digital IDs into everyday transactions and services.

Top user authentication strategies to get ahead of fraud

As the user authentication landscape evolves, adopting the latest strategies is crucial for maintaining security and getting ahead of potential threats. One effective approach is leveraging a comprehensive solution including the Twilio Verify for multi-channel authentication options and the Lookup API for robust phone number intelligence to protect customer accounts and transactions.

Let’s take a look at what you can do to make sure your organization’s authentication methods are strong and take advantage of the latest technologies available.

1. Behavioral analytics for fraud detection

Use risk-based authentication that evaluates the context surrounding a user's behavior and access attempt. This approach uses contextual information to determine the appropriate level of authentication needed, depending on the perceived risk associated with the request. By leveraging tools like Twilio’s Lookup API and Verify Fraud Guard, you can add an extra layer of security by preventing fraudulent transactions and access attempts.  

For example, if a user logs in from a new location, your organization could trigger additional security steps for multi-factor authentication (MFA) methods, such as one-time passwords (OTPs). This strategy lets your organization adapt to varying risk levels while maintaining user convenience. Additionally, Lookup API uses real-time phone number intelligence to check if phone number behavior is suspicious for VoIP and detecting SIM swapping fraud.

These tools analyze a wide array of data points, offering insights that help instantly identify potential threats. By adopting behavioral analytics, organizations can proactively detect and mitigate fraud, safeguarding both their systems and users while maintaining trust in their digital interactions

2. Anomaly detection and response

Implement a strategy that continuously monitors user activity after login to detect any abnormal behavior patterns. By using AI models, organizations can analyze a wide range of indicators, such as typing patterns, mouse movements, and mobile device usage. These insights help verify that the user remains authenticated throughout their session.

This ongoing monitoring allows the system to quickly identify suspicious behavior. If any irregular activity is detected, the system can automatically prompt for re-authentication or even temporarily lock the session. By integrating this approach, organizations can enhance their ability to detect and respond to potential security threats in real-time, ensuring a secure user experience.

3. Layered security approach

Create a layered security strategy by using a variety of authentication methods rather than just one. This approach combines different tools to protect users and make logging in easy and safe. Twilio Verify Passkeys are an integral part of this, enabling businesses to easily add passkeys into their existing user authentication flows. 

But passkeys are only one piece of the puzzle. Combining them with traditional methods like SMS OTPs ensures everyone has options. For example, some users may prefer the convenience of passkeys, while others might stick with the reliable SMS codes they're used to. Twilio makes it easy to create this kind of layered strategy–businesses can quickly blend passkeys with other types of verification. This mix-and-match approach means you can keep your systems safe and your users happy.
