Is Using Fake Names on Social Media Legal in Portugal After the 2026 Policy Reforms?

No, using fake names on social media in Portugal violates the Lei de Serviços da Sociedade da Informação (LSSI) and the Regulamento Geral sobre a Proteção de Dados (RGPD), enforced by the Comissão Nacional de Proteção de Dados (CNPD). Platforms must verify user identities, and impersonation risks fines up to €50,000 under the Código do Consumidor. Exceptions exist for satire or privacy, but these require documented justification.

Key Regulations for Using Fake Names on Social Media in Portugal

  • Mandatory Identification: The LSSI (Decreto-Lei n.º 7/2004) requires social media platforms to collect and verify user identities, prohibiting anonymous profiles unless explicitly permitted by law.
  • RGPD Compliance: The CNPD interprets fake names as potential data falsification, triggering Article 5(1)(c) of the RGPD, which mandates accurate personal data processing.
  • Consumer Protection Risks: The Código do Consumidor (Decreto-Lei n.º 24/2014) penalizes deceptive practices, including impersonation, with administrative sanctions up to €50,000 for repeat offenses.

Platforms like Meta and X must align with Aviso n.º 2023/12 from the Autoridade Nacional de Comunicações (ANACOM), which mandates transparency in user profiles. Since 2026, the Lei de Transparência Digital will further tighten verification protocols, requiring biometric checks for high-risk accounts. Legal exceptions—such as whistleblower protections—demand prior approval from the CNPD or a court order.
