Integrate TrustCaptcha in Angular

Integrate TrustCaptcha with Angular quickly and easily into your website, application or platform in just a few steps and effectively protect your online presence and services from bot abuse.

1 – Sign in or sign up
The first thing you need to do is sign in to your Trustcomponent account. If you do not yet have a Trustcomponent account, you can register with us quickly and easily in just a few steps. After that, go to your dashboard. Here you will see all existing CAPTCHAs and can create new CAPTCHAs.
2 – Choose existing CAPTCHA or create a new CAPTCHA
If you already have a CAPTCHA that you want to use, skip this step. If you don't have a CAPTCHA yet, create a new CAPTCHA now.Create a new CAPTCHADuring the creation process, select the “TrustCaptcha” product category and choose your preferred pricing plan. If you are not yet sure which pricing plan to choose, no problem! The plan can be extended at any time. Then decide whether you want to start with the 30-day trial version or go straight to a paid subscription. If you want to start directly with a paid CAPTCHA, all you have to do is add your billing details and optionally a payment method and you're ready to go.30-day trail periodIf you opt for the 30-day trial period, you can test CAPTCHA for 30 days risk-free. At the end of the 30-day trial period, CAPTCHA locks itself. During the 30-day trial period or up to 30 days after the end of the trial period, you can unsubscribe from CAPTCHA at any time for a fee or delete it with immediate effect. If you neither subscribe to the CAPTCHA for a fee nor delete it within 30 days of the end of the free trial period, it will be deleted automatically.Non-Commercial PlanIn addition to our standard plans, we also offer a permanently free “Non Commercial“ plan with 1 website and up to 500 free verifications for non-commercial websites and projects.
3 – Add your websites and check your credentials
On the dashboard of your CAPTCHA you will find all the important information, statistics and setting options. Here you will also find your site-key, the secret-key and, if available, the license-key. You will need these later on when integrating your CAPTCHA.Add your websitesYour CAPTCHA may only be accessed by websites that you explicitly authorise. To allow websites to access the CAPTCHA, enter all the websites on which you want to integrate the CAPTCHA in the settings.
4 – Solve the CAPTCHA in your frontend
Integrate the CAPTCHA widget into your website or app. You can find detailed instructions for the frontend integration in our documentation. The CAPTCHA widget will then be displayed on your website or app.

Other frontend technology instead of Angular?If you do not want to use Angular or have several websites or applications, you can select a different framework or platform here. If there is no pre-built integration from us for your preferred frontend technology, your software developers can integrate the CAPTCHA themselves using our documentation or ask our support-team for a pre-built integration solution.
5 – Validate the CAPTCHA result in your backend
When the CAPTCHA has finished, take the verification token and send it to your backend. Then retrieve the verification result from our servers and determine your next steps. You can find detailed information on backend integration in our documentation.Prebuild backend integrationsYou can use one of our pre-built integrations to integrate the CAPTCHA validation process into your backend service. If there is no pre-built integration from us for your preferred backend technology, your software developers can integrate the CAPTCHA themselves using our documentation or ask our support-team for a pre-built integration solution.
6 – Congratulations 🎉
You are now protected by TrustCaptcha - congratulations!

Frequently Asked Questions

What is an Angular CAPTCHA?

An Angular CAPTCHA is a client-side component that plugs into Angular forms or APIs and verifies a visitor is human before the request reaches your server. It renders like any other Angular component, emits a verification token and then lets your backend call the provider’s verification endpoint. Modern solutions such as TrustCaptcha auto-start, run invisibly and follow WCAG 2.2 accessibility rules, so users never see a puzzle. Under the hood they combine dynamic proof-of-work with AI-driven risk scoring to make large-scale bot attacks uneconomical.

What is the best Angular CAPTCHA?

The best CAPTCHA for Angular balances security depth, GDPR compliance, accessibility and performance. Many services rely on a single proof-of-work puzzle, but TrustCaptcha layers that puzzle with an AI bot-score and custom rules, reaching a claimed 99.9 % detection rate and five-times stronger protection than PoW alone. Because all data stays on EU servers and a standard Data-Processing Agreement is included, it avoids the consent hurdles that plague U.S.-hosted tools like Google reCAPTCHA. In recent 2025 comparison lists of Angular-ready CAPTCHAs, TrustCaptcha consistently ranks at or near the top for its mix of security and compliance.

How does an Angular CAPTCHA work?

When the widget loads, it triggers a lightweight proof-of-work task that a normal browser solves in seconds, while scaling the cost for botnets. At the same time, passive signals such as device entropy and pointer timing feed an AI engine that returns a bot-probability score. The widget sends both the token to your backend, which calls TrustCaptcha’s EU-hosted verification API and decides whether to accept, rate-limit or block the request. All traffic is encrypted and free of tracking cookies, keeping the flow GDPR-friendly.

Do I need an Angular CAPTCHA?

If your Angular app has login, checkout, chat or API endpoints, a CAPTCHA is still the first line of defence against spam, credential-stuffing and resource-draining bot traffic. Attackers now use AI that cracks image CAPTCHAs with up to 96 % accuracy, so legacy puzzles alone no longer suffice. TrustCaptcha’s invisible, multi-layered model raises the economic bar for bots while boosting conversion rates by eliminating user friction. For most public-facing Angular projects, two minutes of integration beats the ongoing cost of bot abuse.

Is TrustCaptcha GDPR compliant?

Yes — TrustCaptcha stores and processes all CAPTCHA data exclusively in ISO-27001 EU data centres and signs a Data-Processing Agreement with every customer. The service uses no cookies and supports an optional minimal-data mode, so you avoid the extra consent dialogues often required for Google reCAPTCHA. This privacy-first stance aligns with evolving EU guidance on security tools and data minimisation. Choosing a native-EU provider therefore reduces cross-border-transfer risk and paperwork.

Can I customise TrustCaptcha for my brand?

Absolutely. You can tweak every visual element—colours, corner radius, light/dark theme—and even hide the branding entirely or run the widget invisibly. More than 35 languages are supported, with auto-detection and runtime text overrides for full localisation. Developers can also provide a custom privacy-policy link or switch to a completely invisible mode that shows only a subtle status badge. These options let the CAPTCHA blend seamlessly into your design system without extra CSS hacks.
