Brazil's Digital ECA: The World's Most Comprehensive Child Protection Law Requires Age Verification on Every Access

While Australia made headlines with its groundbreaking social media age restrictions for under-16s, Brazil has quietly enacted what may be the most comprehensive child online protection framework in the world. The Digital Child and Adolescent Statute (Digital ECA), signed into law on September 17, 2025, goes far beyond social media platforms—requiring age verification for virtually any digital service that might contain content inappropriate for minors.

Tech Giants Pledge Compliance but Warn of Major Challenges as Australia Introduces Online Verification Law

Bottom Line Up Front: Australia’s Online Safety Amendment (Social Media Minimum Age) Act 2024 is not simply a ban on social media for children—it’s the framework for a mandatory age verification infrastructure that will fundamentally transform how all Australians access the internet. While marketed as child protection, the law

The Catalyst: A Viral Moment Becomes National Law

The speed at which Brazil's Digital ECA became law is remarkable. After Brazilian digital influencer Felipe Castanhari published viral videos exposing the "adultization" of children on social media platforms, public pressure mounted rapidly. Between January and July 2025, SaferNet Brasil registered 76,997 cases of human rights violations online, with 64% (49,336 cases) related to child sexual abuse and exploitation. Following Castanhari's videos, reports of child pornography more than doubled.

The lower house approved the legislation on August 21, 2025, the Senate confirmed it a week later, and President Lula signed it into law on September 17—a legislative sprint of less than one month. The law takes effect on March 17, 2026, giving platforms just 180 days to achieve compliance.

Unprecedented Scope: Beyond Social Media

Unlike Australia's focused approach on social media platforms, Brazil's Digital ECA applies to any information technology product or service that is "targeted at" or "likely to be accessed" by children (under 12) or adolescents (12-18). This expansive definition includes:

• Social media platforms (Facebook, Instagram, TikTok, X)
• Internet applications and websites (including news portals and Wikipedia)
• Computer programs and software
• Electronic games
• Operating systems
• App stores
• Music streaming services (like Spotify, if content contains sensitive lyrics)
• Any service that could have inappropriate content

The law's broad language—"likely to be accessed by minors"—means that even general-purpose platforms must implement protective measures if there's any possibility of minor access.

The Critical Requirement: No Self-Declaration Allowed

The highlighted portion of the law makes one thing crystal clear: for content inappropriate or prohibited for individuals under 18, reliable age verification is required at each access attempt, and self-declaration is not permitted as a method.

This represents a fundamental shift from most current age-gating approaches. Many platforms today simply ask users to confirm they are over 18—a checkbox that requires no verification. Brazil explicitly prohibits this practice for adult content.

What Constitutes "Reliable" Age Verification?

While the law mandates reliable verification, specific technical requirements will be defined through future regulation by the Brazilian National Data Protection Authority (ANPD). Based on international precedents and the law's intent, acceptable methods may include:

• Document verification (government-issued ID checks)
• Biometric age estimation (facial analysis technology)
• Credit card verification (for age, not payment)
• Third-party age verification services
• Age signals from operating systems/app stores (though platforms remain responsible for their own verification)

Importantly, data collected for age verification cannot be used for any other purpose, and providers of pornographic content must prevent minors from creating accounts entirely.

Privacy by Default: The Protective Design Mandate

The Digital ECA establishes "protective design by default" as a core principle. Products and services must adopt the most protective model of privacy, security, and data protection from the outset, based on the best interests of the minor.

Key Protective Measures Include:

Content Moderation Requirements:

• Prevent and mitigate exposure to sexual exploitation and abuse
• Block content involving violence, harassment, and cyberbullying
• Restrict access to content promoting self-harm, suicide, and dangerous behaviors
• Prevent exposure to predatory advertising and gambling
• Block pornographic content
• Classify content by appropriate age groups

Parental Supervision Tools:

• Must be easily accessible and configured to maximum protection by default
• Clear notifications when supervision is active
• Features to limit and monitor usage time, communication, and content
• Restrictions on communication between minors and unauthorized users
• Control over personalized content recommendation systems
• Monitoring of financial transactions and in-app purchases

Prohibited Practices:

• Using profiling or emotional analysis to target minors with advertising
• Employing augmented or virtual reality for commercial advertising to minors
• Monetizing content that portrays children in adult-like contexts
• Paid loot boxes in games accessible to minors (banned entirely)

Social Media-Specific Requirements

For social networks, Brazil imposes additional obligations:

• Accounts for users under 16 must be linked to a parent or legal guardian's account
• Platforms unsuitable for minors must clearly indicate this
• If evidence suggests irregular account usage by a minor, verification measures must be taken and the account promptly suspended
• Providers with over 1,000,000 underage users in Brazil must publish semiannual transparency reports in Portuguese

Mandatory Reporting and Content Removal

Perhaps the most stringent requirement: providers must immediately remove and report content involving exploitation, sexual abuse, abduction, or grooming to both national and international authorities. They must retain related data and metadata for at least six months.

The law also establishes notice-and-takedown procedures that allow victims, legal representatives, the Public Prosecutor's Office, or relevant entities to request content removal without a court order—provided certain formal requirements are met.

Enforcement: The ANPD's New Authority

The Brazilian National Data Protection Authority (ANPD) has been designated as the autonomous administrative authority responsible for implementing, overseeing, and regulating the Digital ECA. Through Presidential Decree No. 12.622/2025, the ANPD gained significant enforcement powers.

Penalties for Non-Compliance:

• Warnings (for minor infractions)
• Fines up to R$ 50 million per violation (approximately USD $10 million)
• Temporary suspension of activities
• Temporary prohibition from operating
• Penalties are scaled based on severity, recurrence, economic capacity, and social purpose

Foreign providers must maintain a legal representative in Brazil empowered to act on behalf of the company before Brazilian authorities.

How Brazil Compares to Australia's Approach

While both countries are pioneering age verification requirements, their approaches differ significantly:

The Global Context: Age Verification Goes Mainstream

Brazil's Digital ECA and Australia's social media age restrictions are part of a growing global movement toward age assurance:

• United Kingdom: Age Appropriate Design Code requires age verification for adult content; Online Safety Act (2025) requires adult sites and some social platforms to verify users are 18+
• European Union: Digital Services Act encourages age-appropriate design but doesn't impose hard age bans
• United States: Individual states like Utah, Arkansas, and Louisiana have passed parental consent laws, though many face legal challenges
• France: Implemented age verification requirements for pornography sites
• Germany: Youth Protection Act requires age verification for content harmful to minors

Brazil's approach is notable for its comprehensiveness—it's not limited to pornography or social media but extends to any service "likely to be accessed" by minors.

Technical Challenges and Privacy Concerns

The requirement for age verification "at each access attempt" presents significant technical and user experience challenges:

Implementation Challenges:

1. Friction vs. Security: Requiring verification at every access could severely impact user experience, potentially leading to VPN usage or other workarounds
2. Technology Maturity: While age estimation technology has improved, it's not perfect. False positives could lock out legitimate adult users; false negatives could allow minor access
3. Data Minimization: The law requires that age verification data not be used for other purposes, but collecting identification documents inherently involves significant personal data
4. Cross-Platform Coordination: Age signals from operating systems and app stores should reduce friction, but platforms remain independently responsible for verification
5. International Compliance: Brazil's extraterritorial application means global platforms must implement Brazil-specific verification flows

Privacy Considerations:

Privacy advocates have raised concerns about the collection of sensitive identity information, even for legitimate age verification purposes. The Digital ECA attempts to address this by:

• Prohibiting the use of age verification data for any purpose other than age confirmation
• Requiring data minimization in age signals from operating systems and app stores
• Allowing multiple verification methods rather than mandating a single approach
• Placing obligations proportionally based on company size and service type

However, the requirement for "reliable" verification at each access—explicitly excluding self-declaration—means some form of identity or biometric data will likely be necessary.

What This Means for Compliance Teams

Organizations offering services in Brazil must urgently assess their compliance readiness:

Immediate Action Items:

1. Scope Assessment

• Determine if your service is "targeted at" or "likely to be accessed by" minors in Brazil
• Evaluate whether your content could be considered inappropriate for any age group
• Document your assessment process for regulatory inquiries

2. Age Verification Implementation

• Identify acceptable verification methods for your service type
• Integrate with age verification providers or develop proprietary solutions
• Plan for "at each access" verification for restricted content
• Ensure verification data is segregated and not used for other purposes

3. Parental Control Systems

• Implement parental supervision tools if targeting minors
• Configure default settings to maximum protection
• Provide clear notices when supervision is active
• Allow limitations on usage time, communication, and content access

4. Content Classification

• Establish age-appropriate content classification systems
• Implement technical measures to prevent minors from accessing inappropriate content
• Create clear age rating indicators

5. Legal and Organizational Preparedness

• Appoint a Brazilian legal representative (required for foreign entities)
• Establish reporting channels for content violations
• Develop procedures for mandatory reporting of CSAM and exploitation
• Prepare for semiannual transparency reporting (if over 1M minor users)
• Train moderation teams on new requirements

6. Data Protection Alignment

• Ensure Digital ECA compliance aligns with LGPD (Brazil's GDPR)
• Conduct Data Protection Impact Assessments for new processing activities
• Update privacy policies to explain age verification practices
• Implement enhanced data minimization for minor users

7. Ongoing Monitoring

• Wait for additional regulatory guidance from ANPD
• Monitor enforcement actions and industry best practices
• Prepare for proportional obligation scaling based on company size
• Plan for potential system audits by ANPD

The Proportionality Question

The Digital ECA includes provisions for proportional application of obligations based on:

• Type of service provided
• Level of provider intervention in content
• Number of users in Brazil
• Size of the company

Services with editorial control and licensed copyrighted content may be partially exempt, provided they adopt basic measures like age classification, transparency, parental mediation, and reporting channels.

Further regulation will define specific criteria for proportionality—a critical detail that compliance teams should monitor closely.

Industry Response and Concerns

While the law passed with overwhelming support in Brazil's Congress, concerns remain:

Platform Concerns:

• TikTok and other major platforms have expressed worry about the implementation timeline
• Meta has indicated it will comply but noted the complexity of verification systems
• Gaming companies are particularly affected by the loot box ban
• Smaller platforms worry about the cost of compliance

Privacy Advocates:

• Concerns about mass collection of identity documents
• Potential for function creep (using age data for other purposes)
• Risk of creating centralized databases of user identity information
• Worry that privacy-preserving methods may not meet "reliable" standard

Child Safety Organizations:

• Largely supportive but concerned about enforcement
• Worry that determined minors may find workarounds (VPNs, borrowed credentials)
• Question whether platforms will invest sufficiently in verification technology

Technical Community:

• Concerns about the "at each access" requirement creating poor user experience
• Worry that friction could drive users to less-regulated platforms
• Questions about how to balance security with privacy
• Uncertainty about which technologies will be deemed "reliable" by ANPD

Looking Ahead: The Global Age Assurance Movement

Brazil's Digital ECA represents a watershed moment in child online protection. By explicitly prohibiting self-declaration and requiring verification at each access, Brazil is setting a new global standard that other countries are watching closely.

President Lula stated that the law represents "a step toward Brazil's digital sovereignty" and criticized Big Tech's lack of self-regulation. He emphasized that "freedom of expression is a nonnegotiable value, but it cannot serve as an excuse for committing crimes in the digital world."

As the March 2026 implementation date approaches, expect:

1. Regulatory Guidance: ANPD will issue detailed technical requirements for "reliable" verification
2. Industry Standards: Age verification providers will develop Brazil-specific solutions
3. Legal Challenges: Some provisions may face constitutional challenges regarding privacy and freedom of expression
4. International Influence: Other countries are studying Brazil's model for potential adoption
5. Technology Innovation: Demand for privacy-preserving age verification will accelerate research and development

Conclusion: A New Compliance Imperative

The Digital ECA is not just another data protection regulation—it's a fundamental reimagining of how minors interact with digital services. The prohibition on self-declaration and requirement for verification at each access represents the most stringent age assurance regime implemented to date.

For organizations operating globally, Brazil's approach signals a clear direction: the era of simple "I am 18+" checkboxes is ending. The future of age assurance involves robust verification, privacy-by-design, and continuous compliance monitoring.

With only 180 days until enforcement begins, compliance teams must act quickly to understand their obligations, implement technical solutions, and establish the governance structures needed to protect minors while respecting privacy. The stakes are high—both in terms of regulatory penalties and, more importantly, in terms of child safety.

The Digital ECA may be the most comprehensive child protection framework in existence, but it's unlikely to be the last. As Brazil and Australia lead the way, expect more countries to follow with increasingly sophisticated age assurance requirements.
