Fixes #864.

What and why

Aliyun RAM's MFA step shows a text box whose only description is its placeholder, 请输入 6 位数字安全码: no otp-ish name, id or autocomplete. Two defects followed from that, both reproduced by the new e2e fixture on main:

• auth login --bwu --totp failed with no field for 'totp'.
• The password step reported signedIn: true while the MFA step was pending. The challenge appears on the same URL, so the fix(auth): do not report a verification step as signed in; take the username field beside the password #867 URL check (verification words in the path) does not fire; the code-hint selectors did not match the box either, so the "needs a verification code" path was skipped and the sign-in confirmation saw the password form gone.

Changes in cli/src/native/actions.rs:

• AUTH_OTP_SELECTORS also matches inputs whose placeholder or aria-label names an authenticator code. 验证器, authenticator and mfa count anywhere. 安全码, 动态码, 动态口令, 动态验证码, 两步验证, 二次验证, 6 位数字 / 六位数字, 2fa, two-factor, security code, authentication code, one-time and 6-digit count unless the same text also names SMS, mail, a phone, an image or a captcha (短信, 手机, 邮箱, 邮件, 图形, 图片, sms, mail, phone, mobile, captcha, image). Password and email inputs and one-digit boxes (maxlength="1") are never matched.
• A bare 验证码 / 校验码 / verification code box (same exclusions) is taken only when the code was asked for (--totp, or a totp step in _autotype). In the default flow such a box may be for a code sent by SMS or mail, and a TOTP must not be typed into it. It is still reported as needs: a verification code.
• AUTH_CODE_HINT_SELECTORS gains 安全码, 动态码, mfa and placeholder security code. A login that has no code to give now reports needs: a verification code on such a page instead of a sign-in.

Second half of #864: this PR is what fixes it for Aliyun's same-URL challenge (hint selectors). #867 also catches MFA steps that move to a /verify, /mfa, /2fa-style URL.

Stealth mode

• Nothing here is visible to the pages chrome-use drives. Only the CSS selector lists change; they run through the same read-only queries as before.

Tests

• Unit: six_digit_security_code_fields_take_the_code checks the real selector lists with a small attribute-selector matcher. It covers Aliyun's placeholder and aria-label, MFA, authenticator-on-phone wording, and the negatives: phone number, SMS, mail, image captcha, password, email, one-digit box, search box, 搜索动态.
• E2E (build host, headless Chrome): e2e_auth_login_bwu_fills_a_six_digit_security_code_field (password step reports needs code, --totp fills and submits once) and e2e_auth_login_bwu_defers_code_to_a_six_digit_security_code_field. Both fail on main (signedIn: true, no needs) and pass with this change.
• cargo test --bin chrome-use and clippy --bin chrome-use on the build host (results in the PR comments).

Summary by CodeRabbit

• New Features
  • auth login --bwu can now recognize one-time verification fields labeled with security-code, authenticator, MFA, or dynamic-code wording, including labels shown as placeholders or accessibility text.
  • Login flows can request a verification code when a matching field is detected, including fields that appear after credentials are submitted.

Walkthrough

auth login --bwu now detects additional MFA and security-code fields. When a code is requested, TOTP phases also match generic verification-code labels. Unit and end-to-end tests cover selector exclusions, code submission, and deferred OTP responses.

Changes: MFA code field detection

Layer / File(s)	Summary
Code-field matching rules cli/src/native/actions.rs	Selectors now include authenticator, MFA, and security-code labels, while excluding labels and inputs associated with unrelated codes. Generic verification-code labels are included only when a code was requested. Selector tests cover matches, exclusions, and non-fillable security-code hints.
TOTP phase integration cli/src/native/actions.rs, cli/src/native/e2e_tests.rs	The totp_only probe and _autotype TOTP step use the requested-code selectors. End-to-end tests cover a placeholder-only security-code challenge, code submission through totpOnly, and deferred OTP responses.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: Low · previous review 55ee3

The Aliyun security-code flow gains coverage, but some SMS fields can receive TOTP values, rejected generic-code challenges can appear successful, and iframe-based explicit TOTP steps can fail. These narrow cases warrant owner awareness and targeted fixes.

- Line 24998: Update the TOTP rejection scan associated with the "totp" step in
the authentication flow to also inspect generic code fields selected by explicit
TOTP steps. Ensure a rejected code on a placeholder-only Verification code input
is detected before confirmation can report signedIn: true for an unchanged page.
- Line 24998: Update scope discovery for explicit autotype sequences to include
the selectors returned by auth_otp_asked_selectors when the sequence contains a
totp step. Preserve the existing top-document and other selector discovery
behavior.
- Around line 24662-24670: Add selectors for authenticator-code labels to the
code hints shown in the diff, so a same-URL challenge with an “Authenticator
code” field is recognized as pending verification and reports needs instead of
signedIn=true.
- Around line 24546-24557: Update the guarded arm of auth_code_label! so its
excluded-code-type checks apply to both placeholder and aria-label, while
preserving the existing label matching and exclusions. Verify a field labeled as
a security code in one attribute but identified as an SMS, email, phone, or
image code in the other is excluded.

CodeRabbit findings, all fixed in 3dde615:

• Guarded exclusions now check both placeholder and aria-label (a security-code box whose other label says SMS is not taken). Tests added.
• authenticator / 验证器 added to the code-hint selectors, so a same-URL "Authenticator code" step reports needs instead of a sign-in.
• check_code_accepted now scans with the selectors the code was looked for with: the asked-for list (bare 验证码 / verification code too) after an explicit totp step, AUTH_OTP_SELECTORS in the default flow.

Build host: cargo test --bin chrome-use 2818 passed; clippy clean; e2e_auth_login* 21/21 on 55ee30a (re-run on 3dde615 pending). The two new e2e tests fail on main with signedIn: true and no needs.
