Microsoft released a record-breaking security update and announced a deadline for customers to migrate to passkey authentication. The move signals a mandatory shift away from password-based authentication across the Microsoft ecosystem.
This Wire brief sits within Fusion42's coverage of Enterprise Software. Wire is Fusion42's founder-focused intelligence feed: each story is connected to the funds and startups it names — every one with a live profile on Raise or Scout — so founders can follow the capital and the momentum behind the headline rather than just the headline itself. Wire analysis is one of the live surfaces Arthur reasons over.
◆ The Wire takeaway
If you sell identity, access control, or workforce authentication tools, your entire customer base is about to be forced to migrate - and Microsoft now owns the default upgrade path. Your customers will either build a passkey bridge to Microsoft or rip you out and replace you with Microsoft's native option.
