Multi-layer authentication has become increasingly important in Brazil and the USA due to rising cybercrime rates. In Brazil, financial institutions and government agencies are mandated by regulations (such as LGPD - Lei Geral de Proteção de Dados) to implement advanced authentication methods. In the USA, it is standard practice in banking, healthcare, and government sectors. The term is widely understood in tech communities in both countries and is becoming more common among general users as security awareness increases.
