Microsoft introduces Passkeys support on Edge for passwordless sign-ins on Windows
Microsoft Edge now lets Windows users create, save, and sync passkeys through its built-in Password Manager. Based on the FIDO2 open standard, passkeys enable passwordless authentication supported by major companies like Meta, Google, and X. They are stored in the cloud in encrypted form and protected by a user-defined PIN.
When users visit a website that supports passkeys, Edge prompts them to create one directly within the Password Manager. The saved passkey can then be used to sign in through fingerprint, facial recognition, or PIN verification. Accessing passkeys from another Windows PC also requires verifying identity with the Microsoft Password Manager PIN.
Currently available only on Windows, Microsoft plans to expand passkey support to other platforms and release a Password Manager plugin that will allow passkey use outside the browser.

While it's nice for them to use FIDO2, I am still very skeptical about the implementation. Since Edge is fully closed source and Microsoft doesn't publish any third party security audit about the browser.
Would be super convenient. Too bad working with the Microsoft ecosystem is infuriating. Maybe one day they'll stop being pushy buttholes.
