"Synced passkeys" offer a convenient way to authenticate across devices – similar to how consumers have learned to authenticate with passwords. For organizations with high security needs, however, the duplication of keys and lack of control when introducing new devices poses a compliance challenge. Additionally, the lack of granularity when suspending or revoking multi-device credentials adds complexity to practical implementations. The good news is that there are strategies for overcoming these challenges, making it possible for banks, fintechs, mobile network operators, and other industries with high security needs to leverage the benefits of passkeys as part of their passwordless journey."
