深色电影风格的仅自拍二次认证堆栈, 四个浮动的半透明玻璃面板以3D透视效果呈现在纯黑色背景上,由一条发光的Didit蓝色线条串联,并由发光的扫描支架框住。每个面板上都有一个小的浅白色图案,分别代表一个循环刷新、两点之间的连接线、一个钟面和一个连续环。

无密码 · 防钓鱼

停止在登录时流失回访用户。两秒钟。他们就回来了。

密码重置会流失约30%的回访用户;短信 (SMS) 验证码可能需要长达90秒。而通过自拍与用户已注册照片进行比对,大约两秒即可完成, 可无缝集成到任何现有的 OAuth / OpenID Connect 流程中。每次二次认证$0.10。每月免费500次验证。

工作原理

从注册到验证用户,仅需四步。

  1. 步骤 01

    创建工作流

    选择您需要的验证项, 身份、活体检测、人脸比对、制裁名单、地址、年龄、电话、邮箱、自定义问题。在控制面板中拖拽构建流程,或通过我们的 API 发布相同流程。支持条件分支、A/B 测试,无需代码。

  2. 步骤 02

    集成

    通过我们的 Web、iOS、Android、React Native 或 Flutter SDK 进行原生嵌入。重定向到托管页面。或者直接通过电子邮件、短信、WhatsApp 等任何方式向用户发送链接。选择适合您技术栈的方式。

  3. 步骤 03

    用户完成流程

    Didit 负责托管摄像头、光线提示、移动设备切换和辅助功能。在用户进行流程时,我们实时评估 200 多个欺诈信号,并根据权威数据源验证每个字段。两秒内即可出结果。

  4. 步骤 04

    接收结果

    实时签名 Webhook 可确保用户通过、拒绝或发送审核后,您的数据库立即同步。按需轮询 API。或打开控制台检查每个会话、每个信号,并按您的方式管理案例。

取代密码 · 跳过短信 · 告别魔术链接

六大功能。每次重新认证 $0.10

一次 Sessions API 调用,一个签名验证结果,即插即用回调契约。结合设备与 IP 分析,在已知良好会话中完全跳过自拍验证。
01 · 一键登录流程

一键。一拍。即刻返回。

发起 Sessions API 调用,将用户重定向到托管的统一资源定位符 (URL),捕获一帧被动图像。活体检测 + 人脸 1:1 比对 + 签名 Webhook 在两秒内返回结果。无需安装应用,无需软件开发工具包 (SDK),无需运营商路径。
生物识别认证模块
02 · 对比密码 / 短信 / 魔术链接

更低摩擦。无钓鱼风险。比短信更便宜。

密码容易被钓鱼、遗忘和重置(每次支持工单成本 $1-$3)。短信 (SMS) 一次性密码容易被钓鱼,依赖运营商,且易受 SIM 卡交换攻击。魔术链接可能被垃圾邮件过滤器拦截。而针对已注册肖像的自拍验证具有防钓鱼、即时且固定价格的优势。
方法矩阵
03 · 转化率提升

不再流失回访用户。

密码重置通常会导致约 30% 的回访用户在流程中流失;短信验证码端到端可能需要 5-90 秒。自拍重新认证大约两秒内完成,无需等待消息,也无需记住任何信息。结果:回访用户登录转化率显著提升。
回访用户基准
04 · 跨平台复用

一次注册。所有 Didit 驱动应用,免费。

将可重用凭证绑定到每个注册用户。下一个需要相同重新认证的Didit驱动界面将以零成本使用该凭证。用户持有证明;您的应用程序验证签名。网络效应在每个发布可重用凭证的客户中复合。
可复用 KYC 模块
05 · 自适应升级认证

在已知设备 + 已知 IP 上跳过自拍。

结合设备与 IP 分析(捆绑在 200 多个欺诈信号堆栈中)。已知设备和已知互联网协议 (IP) 的回访用户可完全跳过自拍。全新设备或新 IP 会触发被动验证;全新设备上的 Tor / 虚拟专用网络 (VPN) 出口会升级到主动 3D 验证。相同流程,智能触发。
设备与 IP 分析模块
06 · 公开定价

每次重新认证 $0.10。全球统一价。

公开定价,无最低消费,无合同。美国一级短信一次性密码每次发送成本为 $0.05-$0.30,即使用户未收到验证码也需付费。密码重置每次支持工单成本为 $1-$3。自拍重新认证固定为 $0.10,每月免费提供 500 次验证,永久有效。

didit-integration-prompt.md
You are integrating Didit&apos;s selfie-only re-authentication into <my_stack>. Replace password, SMS one-time-password, or magic-link on returning-user surfaces with a sub-2-second face match against the enrolled portrait. Phishing-resistant, no carrier dependency, no SIM-swap surface, no email-delivery delay.

  1. Enrol the user&apos;s portrait ONCE at sign-up (standard Know Your Customer (KYC) session).
  2. On every returning-user sign-in, open a re-auth session that runs Passive Liveness + Face Match 1:1 against the stored portrait. ~2 seconds end-to-end.

Pricing (public):
  - Selfie re-auth: $0.10 per authentication (Sessions API)
  - First 500 verifications free every month, forever

PRE-REQUISITES
  - Production API key from https://business.didit.me (sandbox key in 60s, no card).
  - Webhook endpoint with Hash-based Message Authentication Code (HMAC) SHA-256 verification using the X-Signature-V2 header.
  - The user has previously enrolled via a Didit KYC session (the portrait captured during the liveness step is stored automatically, bound to vendor_data).
  - A workflow_id from the Workflow Builder. The workflow MUST contain LIVENESS, and the session is opened with workflow_type = "biometric_authentication".

STEP 1 — Open a re-auth session

  POST https://verification.didit.me/v3/session/
  Headers:
    x-api-key: <your api key>
    Content-Type: application/json
  Body:
    {
      "workflow_id": "<your biometric_authentication workflow>",
      "workflow_type": "biometric_authentication",
      "vendor_data": "<the same user id used at enrolment>",
      "callback": "https://<your-app>/reauth/callback",
      "metadata": {
        "purpose": "returning_user_signin",
        "device_id": "<optional, your device fingerprint>",
        "from_ip": "<optional, the request IP>"
      },
      "portrait_image": "<base64 JPEG of the user's enrolment selfie, ≤ 1 MB — REQUIRED when the workflow has FACE_MATCH active; OMIT for liveness-only mode>"
    }

  Response: 201 Created with the hosted session_url. Redirect the user. The hosted UI opens the front camera, captures one passive frame, runs Liveness + Face Match 1:1 against the user&apos;s enrolled portrait, returns the verdict in sub-2-seconds.

STEP 2 — Read the signed verdict on the webhook

  Body (excerpted for a passing re-auth):
    {
      "session_id": "<uuid>",
      "vendor_data": "<your user id>",
      "status": "Approved",
      "liveness": {
        "status": "Approved",
        "method": "PASSIVE",
        "score": 96
      },
      "face": {
        "status": "Approved",
        "similarity_score": 0.96
      }
    }

  Verify X-Signature-V2 BEFORE trusting the body — HMAC SHA-256 of the raw bytes with your webhook secret.

  Session status enum (exact case): Approved | Declined | In Review | Resubmitted | Expired | Not Finished | Kyc Expired | Abandoned.

STEP 3 — Branch your sign-in logic on the verdict

  Approved      → mint your session token, sign the user in.
  Declined      → block sign-in; fall back to a higher-friction recovery (support contact / full KYC re-do).
  In Review     → hold; route to your operations queue.
  Not Finished  → user abandoned the capture; safe to re-prompt or fall back to a backup factor.

STEP 4 — Adaptive step-up (recommended)

  Pair the selfie with Device & IP Analysis (bundled into the 200+ fraud-signal stack at no extra cost). Adaptive rules to consider:

    Known device + known Internet Protocol (IP)  → skip the selfie, mint a session token.
    Known device + new IP                         → run the selfie (passive).
    New device + new IP                           → run the selfie (passive).
    Tor / Virtual Private Network (VPN) exit +
      new device                                  → escalate to ACTIVE_3D method (motion challenge).

  Implement the branching in your application or in the Workflow Builder via per-session overrides.

CONSTRAINTS
  - Base URL for /v3/* endpoints is verification.didit.me (NOT apx.didit.me).
  - Feature enum is UPPERCASE: LIVENESS, FACE_MATCH, IP_ANALYSIS, ID_VERIFICATION, AML, AGE_ESTIMATION.
  - Method enum is UPPERCASE: PASSIVE, FLASHING, ACTIVE_3D.
  - Auth header is x-api-key (lowercase, hyphenated).
  - Webhook signature header is X-Signature-V2 (NOT X-Signature).
  - Status casing matches exactly: Approved, Declined, In Review, Expired, Not Finished, Resubmitted, Kyc Expired, Abandoned.
  - The face template is irreversible (a one-way hash). The user can request deletion via the standard data-subject-request path.

PRO TIPS
  - Bind a Reusable Credential to each enrolled user. The next Didit-powered surface that needs the same gate consumes the credential at zero cost.
  - Keep a fallback factor (password, magic link, support recovery) for users who cannot complete the selfie — accessibility, device camera failure, religious head covering, etc.

FAQ

常见问题

What is Didit?

Didit is infrastructure for identity and fraud, the platform we wished existed when we were building products ourselves: open, flexible, and developer-friendly, so it works as a real part of your stack instead of a black box you integrate around.

One API covers verifying people (KYC, know your customer), verifying businesses (KYB, know your business), screening crypto wallets (KYT, know your transaction), and monitoring transactions in real time, on a stack built to be:

  • Fast, sub-2-second p99 on every session
  • Reliable, in production with 1,500+ companies across 220+ countries
  • Secure, SOC 2 Type 1, ISO 27001, GDPR-native, and formally attested by Spain's financial regulator as safer than verifying someone in person

The footprint underneath: 14,000+ document types in 48+ languages, 1,000+ data sources, and 200+ fraud signals on every session. The Didit infrastructure dynamically learns from every session and gets better every day.

What is "selfie-only re-auth"?
A sign-in flow where the only thing the user does is take a selfie. No password to type, no Short Message Service (SMS) code to wait for, no magic link to fetch from email. The selfie is matched against the user's enrolled portrait, captured during their original Know Your Customer (KYC) session, and a session token is minted in roughly two seconds.
Why are passwords still a problem in 2026?

Three reasons that have not improved:

  • People forget them. Industry surveys put password-reset rate at roughly 5-10% of monthly active users for most consumer apps. Each reset is a $1-$3 support ticket.
  • People reuse them. A breach on any one site exposes credentials reused everywhere else. Credential-stuffing attacks remain the #1 account-takeover vector.
  • People type them on the wrong site. Phishing pages cost the user the credential the moment they hit Enter.
How fast is the verification for my end user?

The full flow normally takes under 30 seconds end-to-end, pick up the ID, snap the document, snap the selfie, done. That is the fastest in the market. Legacy KYC providers usually take more than 90 seconds for the same flow.

On the back end, Didit returns the result in under two seconds at p99, measured from the moment the user finishes the selfie to the moment your webhook fires. Mobile capture is tuned for slow phones and slow networks: progressive image compression, lazy software development kit load, and a one-tap hand-off from desktop to phone via QR code if the user starts on web.

Why is this faster than Short Message Service one-time-password (SMS OTP)?

SMS one-time-password has a delivery tail of 5 to 90 seconds depending on carrier, country, and time of day. Even in the best case, the user waits, switches apps, copies a 6-digit number, switches back, pastes it, and hits submit, total time-to-signed-in is 15 to 120 seconds.

A selfie is one tap, one camera frame, one verdict, roughly 2 seconds end-to-end with no app switch, no copy/paste, no message that never arrives.

What happens if a user fails, abandons, or expires?

Every session lands on one of seven clear statuses, so your code always knows what to do:

  • Approved, every check passed. Move the user forward.
  • Declined, one or more checks failed. You can allow the user to resubmit the specific failed step (for example, re-take the selfie) without re-running the whole flow.
  • In Review, flagged for compliance review. Open the case in the console, see every signal, decide approve or decline.
  • In Progress, user is mid-flow.
  • Not Started, link sent, user has not opened it yet. Send a reminder if it sits too long.
  • Abandoned, user opened the link but did not finish in time. Re-engage or expire.
  • Expired, the session link aged out. Create a new session.

A signed webhook fires on every status change, so your database always stays in sync. Abandoned and declined sessions are free.

Where does my customer data live and how is it protected?

Production data is processed and stored in the European Union by default, on Amazon Web Services. Enterprise contracts can request alternative regions for jurisdictions whose regulators require it.

Encryption everywhere. AES-256 at rest across every database, object store, and backup. Transport Layer Security 1.3 in transit on every API call, webhook, and Business Console session. Biometric data is encrypted under a separate Customer Master Key.

Retention is yours to control. Default retention is indefinite (unlimited) unless you configure shorter, between 30 days and 10 years per application, and you can delete any individual session at any time from the dashboard or the API.

Certifications: SOC 2 Type 1 (Type 2 audit in progress), ISO/IEC 27001:2022, iBeta Level 1 PAD, and a public attestation from Spain''s Tesoro / SEPBLAC / CNMV that Didit''s remote identity verification is safer than verifying someone in person. Full report at /security-compliance.

Is Didit compliant for my industry?

Didit ships compliant by default for the regulators that matter to identity infrastructure:

  • GDPR + UK GDPR, controller / processor split, full Data Processing Agreement published, lead supervisory authority named (Spain''s AEPD).
  • AMLD6 + EU AML Single Rulebook, 1,300+ sanctions, politically exposed person, and adverse-media lists screened in real time.
  • eIDAS 2.0, EU Digital Identity Wallet aligned; reusable-identity ready.
  • MiCA (Markets in Crypto-Assets), ready for crypto on-ramps, exchanges, and custodians.
  • DORA, Digital Operational Resilience Act, EU financial-services operational resilience.
  • BIPA, CUBI, Washington HB 1493, CCPA / CPRA, US biometric privacy (Illinois, Texas, Washington) and California consumer privacy.
  • UK Online Safety Act, age-gating and child-safety obligations.
  • FATF Travel Rule, originator and beneficiary data on crypto transfers, IVMS-101 interoperable.

Detailed memo, every certificate, every regulator letter: /security-compliance.

How fast can I integrate and start verifying users?
  • 60 seconds to a sandbox account at business.didit.me, no credit card.
  • 5 minutes to a working verification through Claude Code, Cursor, or any coding agent via our Model Context Protocol (MCP) server.
  • A weekend to a production-ready integration with signed-webhook verification, retries, and a remediation flow when a user is declined.

Three integration paths, pick whichever fits your stack:

  • Embed natively with our Web, iOS, Android, React Native, or Flutter SDK.
  • Redirect the user to the hosted verification page, zero SDK.
  • Send a link by email, SMS, WhatsApp, or any channel, zero front-end work.

Same dashboard, same billing, same pay-per-success price for all three. Step-by-step guide at docs.didit.me/integration/integration-prompt.

What does the integration actually look like?

It's a drop-in for any existing returning-user callback contract.

  • POST /v3/session/ with workflow_type: "biometric_authentication" and the same vendor_data you used at enrolment.
  • Redirect the user to the returned session_url.
  • Verify the X-Signature-V2 Hash-based Message Authentication Code (HMAC) header on the webhook.
  • Branch on status, Approved mints your token, Declined blocks and falls back, In Review routes to ops, Not Finished re-prompts.

Most teams ship it in a weekend. Full agent-pastable prompt is above; Model Context Protocol (MCP) server speaks both surfaces.

How do you handle the user's face data?

Data minimisation by default. The selfie is processed in memory, the verdict and similarity_score persist, and the raw image is deleted unless retention is explicitly enabled. The enrolled portrait is stored as an irreversible face template, a one-way hash you cannot reconstruct the original face from.

We never sell, share, or train third-party models on a customer's biometric data. End users can request deletion of their template at any time via the standard data-subject-request path.

What happens if the user's face has changed?

Face Match 1:1 is resilient to moderate appearance change, haircut, beard, glasses, lighting, makeup, modest ageing. The similarity score returned per re-auth reflects the model's confidence.

For users who drift outside the auto-approve threshold (dramatic weight change, surgery, multi-year ageing without a refresh), the verdict returns In Review and routes to your operations queue. A 10-second re-enrolment session refreshes the template, and the next re-auth uses the new portrait.
