A TOTP was fetched before filling the username/password, so a multi-step login could use up its lifetime before the challenge appeared. Default password login now waits for a code field, then uses a second audited bwu run with the same selected item and pinned origin. Authorization may be requested again for that phase.
auth login --bwu --totp --item <id|name> completes an existing authenticator challenge while reading only TOTP and skipping username/password and _autotype. It is incompatible with --passkey and --no-submit. Custom _autotype keeps its existing timing; an attempted code is never automatically replayed after failure.
Pending verification now has an explicit text result and needs/next in JSON. Auto-login leaves that page in place. Code fields are included in sign-in confirmation, including when a rejected code remains nonempty. Setup guidance explains that the vault needs the authenticator setup key, and that SMS/email/push use separate sources.
Stealth mode
Nothing here is visible to the pages chrome-use drives.
Something here is page-visible and it only runs with stealth mode off.
Uses the existing trusted CDP input and closure-scoped auth handles. No new page globals, DOM markers, listeners or requests are injected. Fixture acceptance checks trusted code input and that no extra globals/attributes remain.
Tests
Run on the configured SSH build host, verified as m3b; no local browser was opened:
Ordinary unit suite: 2630 passed, 4 ignored.
Real Chrome e2e_auth_login_bwu_ suite: 12 passed, including delayed challenge, missing code, TOTP-only and rejection without retry.
Remote clippy and formatting checks passed.
Static documentation SEO check: 83 pages passed.
Full CLI subprocess acceptance against the final checksummed debug build, with a mock vault and real Chrome: 5 passed (default two-step, TOTP-only, rejected code, missing seed, no-submit). The fixture checks the actual entered credentials/code; no fixture values appeared in stdout/stderr.
No personal vault entries were accessed. Real Aliyun account acceptance and a public-detector stealth benchmark have not been run. No release or local installation is included.
Docs
Help, README (EN/ZH), skill-data and docs (ZH + EN) updated.
Changelog entries will be added when preparing the release.
Bitwarden login can handle authenticator-code challenges: password login retrieves a code only after the challenge appears, then submits it using the same vault item.
Use --totp to submit a code for an existing challenge without re-entering credentials. The selected vault item must contain an authenticator setup key.
Pending verification is reported separately from confirmed sign-in. Unsupported verification fields remain pending, rejected codes are not retried, and --totp cannot be combined with --passkey or --no-submit.
Documentation
Updated login guidance and examples in English and Chinese.

Walkthrough
The Bitwarden login flow now supports retrieving TOTP after a verification challenge appears and submitting a current challenge with --totp. The CLI handles phase responses, reports pending verification separately from confirmed sign-in, and updates help and documentation.
Changes: Bitwarden TOTP login
Layer / File(s)
Summary
TOTP options and child preparation cli/src/bwu_login.rs, cli/src/commands.rs
The CLI adds --totp, rejects incompatible options, and prepares child runs to defer TOTP or submit only a TOTP code.
The login action detects OTP challenges, tracks code attempts, and reports the next verification step. Tests cover deferred entry, rejected codes, and missing or unsupported codes.
Login phases and response validation cli/src/bwu_login.rs, cli/src/native/e2e_tests.rs
The parent parses child responses and starts one TOTP-only phase when the first phase reports a deferred challenge. It combines phase results and does not retry rejected codes.
Login reporting and usage guidance cli/src/output.rs, README.md, README.zh.md, docs/*/login-auth.html, skill-data/core/*
Output distinguishes pending verification from confirmed sign-in. Help and documentation describe TOTP setup requirements, option restrictions, and login behavior.

Check for a code field before accepting a deferred sign-in.
After the 10-second wait, confirm_sign_in accepts a ready page that has no password field. It never checks for a code field. A TOTP challenge that appears after the wait is reported as a finished login, and run_login_phases skips the code phase.

Minor · Pin the phase-two tab identity before submitting the TOTP code. · bwu_login.rs:755-769
Pin the phase-two tab identity before submitting the TOTP code.
The second auth login --bwu --totp run checks only that the active tab is session-owned and has the pinned origin. After the vault authorization pause, a different same-origin challenge in that tab can receive the selected item's TOTP. The code is then rejected, which consumes an attempt on that challenge. Pin the observed challenge's tab or page identity from phase one and verify it at the start of phase two.

Update the two-phase login flow around login_response to retain the observed

phase two, before submitting the selected item’s TOTP. Reject the phase-two run
if that identity no longer matches, even when the active tab has the same

Add a test that runs prepare on a password-and-code vault item.
The new phase test builds Prepared { defer_otp: true } by hand. It skips the deferral decision in prepare. A change that adds CU_BWU_OTP to the first child's envs, or clears defer_otp, would still pass the test suite.

Limit the signed-in probe's code-hint match to genuine code fields.
On an auto run, the signed-in quick probe now matches AUTH_CODE_HINT_SELECTORS on the default path. The merge base did not match these selectors on this probe on any path. A visible input whose id or name contains verification satisfies the probe on a page with no sign-in form. The signed-in shortcut is then skipped. When the item supplies no username or password value, the response reports a pending verification code instead of alreadySignedIn. Nothing is filled or submitted, so the impact is a misleading status. The --otp and deferred-OTP paths gain the same match.
Preconditions:
auto is set, the current URL is not a sign-in URL, and the run is not totp_only.
The item supplies no username or password value, so the code-hint branch runs.
A visible input has verification in its id or name.
Removing the hint selectors from the default probe stops this match for unrelated fields. It can also misreport a genuine code-only challenge as alreadySignedIn when that page's code field matches only the hint selectors. The probe must match real code fields and exclude unrelated verification-named inputs. The inspected code does not establish a selector change that does both, so no patch is proposed.

Minor · Deferred login can submit the vault TOTP into an SMS or email code… · actions.rs:24492-24496
Deferred login can submit the vault TOTP into an SMS or email code field.
The defer_otp probe treats any visible field matching AUTH_OTP_SELECTORS as ready for a TOTP. The first selector, input[autocomplete=one-time-code], also matches SMS and email code fields. After password submission, the parent runs a second phase with totp and enter steps for that field. The flow does not check whether the challenge comes from an authenticator app. A wrong-source code is submitted once. The code is not retried, and the error is reported as TOTP verification stopped.
Setup guidance in skill-data/core/references/authentication.md says SMS, email, and push approval need their own source. The default flow does not apply that distinction at runtime. Limit the TOTP phase to fields that identify an authenticator challenge, or add a source-specific opt-in. A safe selector for that check was not established, so no code change is proposed here.
