Certillion

Certillion is a powerful Chrome extension that lets you digitally sign documents on your phone using ICP-Brasil compliant certificates such as e-CPF and e-CNPJ. It combines the legal validity of manual signatures with the speed of online document transmission and the convenience of mobile access, eliminating the need for printing, queuing, or mailing documents.

Leveraging the best security technologies, Certillion supports signing contracts, paying bills, issuing electronic invoices, and accessing secure government portals directly from your mobile device. Users can either obtain a free digital certificate at registered service points or use their existing A1 digital certificates. Supported by major Brazilian institutions like FINEP, the Ministry of Science and Technology, and ITI, Certillion ensures secure and efficient transactions aligned with ICP-Brazil standards.
