Top user authentication trends for 2026

Top user authentication trends for 2026

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 in the AI era

In 2026, the challenge of combating AI-generated deepfakes and synthetic identities will demand sophisticated fraud detection strategies. Don't just check if a user profile is real—watch how they actually behave so your system can automatically decide whether to let them in, test them, slow them down, or block them. 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.

Identity verification for KYA and phone number validation

As organizations layer security ahead of the login box, the traditional paradigm of Know Your Customer (KYC) is evolving into Know Your Agent (KYA). While classic KYC verifies a human's government ID before opening an account, the rise of autonomous AI assistants demands a new standard. KYA establishes a verified digital identity connecting an AI bot directly to the enterprise it represents and the official phone line or messaging channel it operates on, giving customers instant proof that an agent is legitimate rather than a scammer.

Documentation checks with baseline structural data is critical. When security teams ask us for the ideal way to handle this modern identity verification, we we point them toward a unified approach: combining an identity document verification vendor alongside Twilio Lookup is the gold standard for a complete, frictionless onboarding stack. While document verification confirms government IDs and biometric liveness, Twilio Lookup provides background phone number validation, checking carrier histories, SIM-swap status, and line-types to eliminate synthetic fraud before the KYC check even begins.

Combining robust identity verification with intelligence like Twilio Lookup creates a frictionless onboarding process that protects the front door for human customers and AI agents alike.

Adaptive authentication for the agentic era

Identity and Access Management (IAM) is undergoing a transformation, with zero trust models becoming the standard for enterprise security. Organizations are shifting from status session login risk to trust inside the conversation. Security doesn't stop after a user types a password or scans a fingerprint. Because people now interact with apps through AI chat or voice, security checks need to happen continuously inside the conversation itself. 

Now that autonomous AI agents are taking real actions—not just humans tapping screens—systems have to evaluate risk on the fly to keep AI within boundaries. That means dynamically controlling what data a bot can touch mid-chat and seamlessly pausing the AI and asking a real human to step in and give explicit permission, also known as human-in-the-loop. 

Moving beyond passkeys to multi-channel authorization

Passkeys are a great step forward for passwordless logins, but identity security in an agentic world requires more than an initial biometric check. Modern trust relies on native multi-channel verification, rich contextual risk signals, and dynamic in-flight approvals rather than treating additional channels as simple legacy fallbacks.

SMS, Voice, push, and WhatsApp serves as Twilio’s native infrastructure for triggering real-time human approvals when an AI agent requests more authority. In an agentic era, trust relies on native multichannel verification, contextual risk signals, and dynamic in-flight approvals rather than legacy fallback channels.

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. Introducing agent identity

Instead of giving AI unrestricted access, organizations can now grant bots tightly scoped permissions tied directly to a specific user or business, complete with clear expiration dates and real-time tracking so you always know who owns which bot.

At the same time, systems need automated defenses against malicious automation, credential abuse, and data scraping. By continually analyzing programmatic traffic patterns, security teams can apply dynamic risk decisioning in real time:

• Allow: Let legitimate AI agents seamlessly carry out authorized tasks.

• Challenge: Trigger a step-up check or human-in-the-loop approval when risk signals spike.

• Throttle: Slow down suspicious programmatic traffic attempting high-frequency requests.

• Block: Instantly shut out bad bots, scrapers, and rogue automation before they touch sensitive systems.

With strict boundaries, expiration limits, and proactive threat response, organizations can confidently deploy AI helpers at scale, ensuring every bot stays verified, accountable, and securely in bounds.

2. 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

3. 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.

4. 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.
