📄 Description

Summary

Adds the long-requested "Log in with passkey" feature: passwordless
account login via a discoverable WebAuthn credential, with optional
PRF-based vault unlock. This consolidates the prior efforts in #6820
(@samos667) and #5929 (@zUnixorn) into a single review-ready PR, as the
maintainers suggested on those threads. The foundational commit retains
@samos667 as author and credits @zUnixorn via Co-authored-by:; the
remaining commits are my own.

What it does

• Passwordless login (grant_type=webauthn): a discoverable, user-verified
  WebAuthn assertion authenticates the user. Per Bitwarden's model the
  authenticator's user-verification is the second factor, so TOTP is not
  re-prompted.
• PRF vault unlock: a passkey can carry a wrapped key set so the vault can
  be unlocked with the passkey. Exposed via webAuthnPrfOptions on /sync
  and UserDecryptionOptions at login, matching the Bitwarden web client.
• Passkey management: enroll, list, and delete account passkeys
  (/api/webauthn*), each gated by password/OTP.
• Key rotation: post_rotatekey re-wraps the account-key-wrapped PRF
  material so rotating the account key no longer silently breaks passkey unlock.
• prfStatus implemented (Enabled / Supported / Unsupported), replacing
  the previous placeholder.
• Availability advertised via the pm-2035-passkey-unlock config flag and
  suppressed under SSO_ONLY or a WebAuthn-incompatible DOMAIN.

Threat model

The login and key-handling paths defend against:

• Replay of a captured assertion (single-use transactional login
  challenges; signature-counter advance with CAS rollback protection).
• Account/credential enumeration via the unauthenticated grant
  (uniform Passkey authentication failed response across every failure
  branch — unknown user, missing credential, verification failure, account
  disabled or unverified — gated by an IP-shared login rate limit).
• Cross-user credential misuse (every passkey CRUD and read is
  per-user-scoped at the DB layer; credential ID hashes are unique per user
  rather than global).
• Passkey-unlock breakage on key rotation (post_rotatekey re-wraps each
  PRF credential's account-key-wrapped material under the new account key as
  part of the rotation; a concurrent passkey delete during rotation is
  tolerated as a best-effort degraded no-op).
• Audit-log poisoning by anonymous probes (pre-verification failures
  deliberately omit the UserFailedLogIn event so an attacker submitting
  forged user-handles cannot create audit entries on the victim's account).

Hardening

A few changes also tighten shared paths beyond passkey login — flagged here
since they affect more than the new feature:

• 2FA-policy enforcement is now fail-closed (enforce_2fa_policy): a
  transient DB error while loading a user's Require-2FA org memberships
  previously collapsed to an empty set and silently skipped enforcement; it now
  propagates. This closes the same gap for password login and recovery-code use.
• SSO_ONLY is enforced deny-by-default at the token endpoint across all
  grant types, replacing the previous password-only per-grant check.
• The 2FA-WebAuthn endpoints and is_webauthn_2fa_supported are hardened
  against a malformed DOMAIN that could previously panic a worker thread
  (.expect() → graceful refusal); every WebAuthn entry point is now gated.
• Several shared DB lookups now return Result instead of swallowing
  errors into None, so a transient failure surfaces rather than being misread
  as "not found".

Database

Two new additive tables (web_authn_credentials,
web_authn_login_challenges) with migrations for all three backends. No
existing data is migrated — webauthn-rs 0.5 is already in main, so the
2FA-object migration discussed on #5929 does not apply here.

Testing

• Builds on #7248, which brought the Playwright suite back to green against the
  current bundled web-vault; the new E2E specs run on that harness, so whoever
  reviews/merges this may want to take #7248 alongside it. The first 8 commits
  of this PR's diff are #7248's; the webauthn-specific work starts at
  1cdf0b7b.
• cargo fmt / clippy / test and the Playwright E2E suite pass. New Rust
  unit tests cover the PRF/UserDecryption response shapes, challenge
  freshness + single-use, and passkey-rotation validation.
• Playwright coverage: passkey login, PRF enrolment + unlock, the full
  enrol → login → lock → unlock → rotate → remove lifecycle, the rejection
  paths (disabled account, deleted credential, runtime-unusable 2FA), SSO_ONLY
  denial, and malformed-input rejection.

Compatibility

Wire shapes (UserDecryptionOptions, webAuthnPrfOptions, GetPrfStatus)
follow the upstream Bitwarden server so the official web client works
unchanged.
