Legally sign documents online with Mobile-ID

Use your existing digital proof of identity and sign important documents online with the highest signature standard.

Portrait

Mobile-ID is an electronic identity document that is fully supported by the government in Estonia and is gaining popularity in Lithuania. Its online use is very similar to an ID card, but no smart card reader is required. You can use it to authenticate yourself (e.g. log in to banks, websites, government offices, etc.) and sign documents (confirm transactions, sign legally binding contracts, etc.). Mobile-ID meets the highest security standards for personal identification. Electronic signature with Mobile-ID is equivalent to handwritten signature. Mobile-ID is eIDAS certified.
