Autenti certificate – digital evidence of a declaration of intent, authenticated by a trusted third party

An Autenti certificate is a confirmation of an online signature. It is digital evidence for the meeting of the parties and their conclusion of an agreement on the platform being a trusted third party. It contains all the necessary details on the process and its parties, and confirms the integrity and authenticity of signed files. Autenti certificates have already been admitted as evidence in disputes and by courts.

Possibility to sign any electronic files

On Autenti you can sign any documents, no matter the file format. A text document, image or spreadsheet – just drag and drop them to the platform and send to the recipient. Files are combined and bound to the .pdf format, and displayed on the recipient’s device in a convenient form, regardless of the number of pages.
