Passkeys Cross the Adoption Threshold as Password Managers Add Native Support

Passkey adoption has moved past the early-adopter phase this year, driven less by platform mandates than by password managers finally solving the cross-device portability problem that held the technology back. For the first three years after passkeys launched, the biggest practical objection from security teams was reasonable: a passkey tied to a single device ecosystem meant losing that device could mean losing access entirely, and moving between an iPhone and a Windows laptop was clunky. Third-party password managers have now closed that gap, syncing passkeys the same way they always synced passwords, across any device with the manager installed. The security case for the switch remains strong: passkeys are phishing-resistant by design, since the cryptographic challenge is bound to the actual domain, which means a fake login page simply cannot capture a usable credential the way it can capture a typed password. For platforms weighing whether to invest in passkey support now, the calculus has shifted from "wait for the ecosystem to mature" to "the ecosystem has matured" — implementation cost is the main remaining variable, and it continues to drop as more identity providers ship it as a standard, low-effort integration option.
