Contact centers are evolving from handling interactions to orchestrating actions. As a result, customer authentication is moving from a front-door checkpoint to a reusable assurance layer. In modern contact centers, authentication must flex: invoked when needed, proportionate to action risk, and returned as a signal that both agents and automation can use. Passkeys, as a phishing-resistant and cryptographically secure form of authentication, arrive at exactly the right time in contact center environments.
For several years, contact centers have treated customer authentication as a fixed cost: a set of security questions, a wait while an agent checks account details, and a step customers tolerate because in many cases, there was never an obvious alternative. That assumption is no longer accurate: passwordless authentication built around passkeys is becoming one of the most widely adopted pieces of consumer technology in recent years, and it is arriving at exactly the moment contact centers are trying to layer AI and automation onto their interactions.
Passkeys are not a future concept still waiting for adoption. They already sit on hundreds of millions of devices, used every time someone unlocks a banking app with a fingerprint or signs into an email account with a face scan. The FIDO Alliance reports five billion passkeys in use worldwide. Their 2026 survey found 90% of consumers are aware of passkeys, and 75% have already enabled one on at least one account.¹
Passkeys no longer represent an unfamiliar practice, they extend a pattern that customers already use in their digital lives.
For contact center, service operations and CX leaders, the opportunity is to apply that familiar pattern to a much more complex environment: one where customer journeys move between agents, self-service and interaction channels.
Why passwordless authentication matters now
Passwordless authentication solves a problem that has been building inside contact centers for years. Shared secrets have become easy to obtain, agent judgment varies from one interaction to the next, and each additional verification step adds handle time without always adding certainty. A cryptographic check removes the guesswork: either the customer holds the registered device and passes the local biometric, or they don’t. There’s no script for a fraudster to talk their way around, and no inconsistency for a compliance team to explain after the fact.
The same property makes identity portable in a way that knowledge-based methods never allowed. Because the credential lives with the customer rather than inside a single channel’s script, a passkey verified in a mobile app can carry the same weight when that customer reaches a live agent or interacts with a bot, cutting out the repeated verification that has made channel handoffs a source of frustration. Most organizations aren’t making this change in one step: Passwordless methods tend to be layered in alongside existing authentication, extended first to the highest-value or higher risk interactions while legacy methods continue to run in parallel.
Because not every customer journey has the same risk, a status update, refund, account recovery, or a payment do not require identical assurance. Contact centers need authentication that is proportionate to the action and that can travel with the workflow:
- A status enquiry may require minimal friction.
- A refund or account change may need stronger verification.
- A bot-to-agent handoff may need identity context to persist.
Passkeys support this by producing a clear authentication outcome. The organization gets a reusable signal, instead of an agent’s interpretation applied inconsistently across interactions. This allows service designers to match assurance levels to journey risk, reducing repeated checks and making handoffs smoother.
Built for where service Is headed
In traditional knowledge-based authentication models, agents ask questions and interpret responses. Passkeys shift that work by delivering a structured authentication signal. Agents receive a clear outcome while automated workflows gain a machine-readable trust input. For operations leaders, this means fewer repeated checks and more consistent outcomes. For CX, it reduces friction across channels. For digital transformation, it means authentication can be consumed as a service across channels and workflows.
The case for passwordless authentication gets stronger, not weaker, as contact centers automate. Gartner expects agentic AI to autonomously resolve 80% of common customer service issues without human involvement by 2029, cutting operational costs by roughly 30% along the way.²
Before any of that automation can be trusted with an account change or a sensitive service request, something has to confirm who the customer actually is, in a form a machine can act on with confidence. A cryptographic check gives an AI agent exactly that: a clear, verifiable signal, rather than an interpretation of a spoken answer.
None of this replaces the value of a person on the other end of the line, however. PwC’s 2025 Customer Experience Survey found that 86% of consumers still rate human interaction as moderately or very important to their brand experience, even as AI and automation become more embedded in customer journeys.³ Passwordless authentication supports that reality rather than working against it: when identity is already confirmed cleanly before a customer reaches an agent, that agent spends their time solving the actual problem instead of re-establishing who they’re talking to. The technology’s job is to get trust settled quickly and consistently, whatever comes next in the interaction, human or automated.
Designing authentication as service infrastructure
Passwordless authentication is no longer an idea contact centers can file under “eventually.” It is already part of how many customers access the rest of their digital lives, and the gap between that experience and traditional support journeys is becoming harder to justify.
For contact center, service operations and CX leaders, the opportunity is to bring identity verification up to the same standard as the rest of the customer experience. That means treating authentication less as a fixed step in the journey and more as service infrastructure:
- Flexible enough to support different channels
- Strong enough for sensitive actions
- And clear enough for agents and automated workflows to act on.
Passkeys offer a practical pattern for that shift. There is no shared secret to remember, the customer experience is familiar and device-based, and the business receives a clearer assurance signal that can support assisted, digital and automated journeys. For Ops, that can mean fewer repeated checks and more consistent handling. For CX, it can mean authentication that feels more aligned with customer expectations. For digital transformation teams, it can mean a stronger foundation for automation and omnichannel orchestration.
As contact centers become more automated, more connected and more AI-enabled, the organizations that modernize authentication now will be better placed to support sensitive customer journeys without forcing a trade-off between security, efficiency and experience.
For teams rethinking how customer identity should work across assisted and automated interactions, passkey-based authentication offers a practical place to start.
