Passwords are often an organisation’s weakest link. On World Password Day (May 5), Apple, Google and Microsoft jointly announced that they were building in support for passwordless sign-in, leveraging FIDO2, across all of the desktop, browser and mobile platforms that they control. Crucially, they have all emphasised cross-platform functionality will be a high priority in the development of FIDO2-based passwordless features. With the help of its community of identity, security and biometrics experts, the FIDO Alliance has developed and promoted free, open standards that have taken passwordless authentication to the next level.
