WebAuthn authentication process consists in two _ceremonies_: attestation, and assertion.
|
||||
Passkeys, hence WebAuthn, consists in two _ceremonies_: attestation, and assertion.
|
||||
|
||||
Attestation is the process of asking the authenticator (a phone, laptop, USB key...) to create a private-public key pair, and **register** the public key inside the app. For that to work, the user must exist, and the browser must support WebAuthn, which is what intermediates between the authenticator (OS & device hardware) and the app.
|
||||
Attestation is the process of asking the authenticator (a phone, laptop, USB key...) to create a private-public key pair, save the private key internally, and **store** the public key inside the server. For that to work, the browser must support WebAuthn, which is what intermediates between the authenticator (OS & device hardware) and the server.
|
||||
|
||||
Assertion is the process of pushing a cryptographic challenge to the device, which will return back _signed_ by the private key. Upon arrival, the app checks the signature is correct with the stored public key, ready to **log in**.
