Major platforms like Apple and Google support them, demonstrating high adoption rates among organizations. Passkeys improve sign-in success rates and reduce helpdesk incidents, yet usability challenges persist, especially across different operating systems. Ultimately, they represent a significant advancement in secure online identity verification.
