Gov.br is Brazil's national single sign-on and digital identity platform, giving citizens one account to authenticate across thousands of federal, state, and municipal services. It uses a tiered assurance model of bronze, silver, and gold, where higher levels unlock more sensitive services. It also supports legally valid electronic signatures.

The CIN is Brazil's new national identity card that adopts the CPF as the single unified identification number under Law 14.534/2023, replacing the old state-issued RG. It is available in physical and digital formats via the gov.br app and includes a QR code, a machine-readable zone, and biometric data. It is valid across Brazil and Mercosul.
