How to encourage passkey creation on multiple devices?

Multi-device passkey coverage is critical because users typically interact with payment platforms across various devices - such as smartphones, tablets, laptops and even shared family computers. If passkeys aren't available on all user devices, individuals will be forced back to fallback authentication methods like passwords or OTPs, resulting in increased friction, higher operational costs, and lower adoption rates.

Seamless authentication across all user devices ensures frictionless payments, improving user satisfaction and reducing cart abandonment rates.

Wider passkey availability minimizes the need for less secure fallback methods, significantly enhancing overall security and reducing vulnerabilities related to phishing and credential theft.

Providing a consistent authentication experience across multiple devices reinforces user trust and encourages more frequent passkey usage.

After a user registers their first passkey, providers should prompt users to easily add passkeys to additional devices upon subsequent logins.

If users log in on devices without existing passkeys, providers can offer quick options (such as QR code scanning or cross-device authentication) to seamlessly create a new passkey on the current device.

Clearly communicate the benefits of multi-device coverage through targeted user education campaigns, emphasizing security, convenience, and ease of use.

Regularly track metrics such as multi-device coverage rates and fallback method usage to continuously improve passkey adoption strategies and proactively address device coverage gaps.

By focusing on comprehensive multi-device passkey coverage, payment providers can offer users a frictionless and secure checkout experience across all devices, closely resembling successful native solutions like Apple Pay.
