FAQ – Key issues about our digital signature

Are inSign electronic signatures legally compliant?
The electronic signature can be used for legal purposes in all European Union countries and cannot be rejected as evidence. inSign supports all signature types (SES, AES, QES). By default, when using inSign, an advanced electronic signature (AES) is created in compliance with eIDAS. Likewise, sensitive topics such as data protection, transmission and storage are top priorities for us (in particular with regard to the change in the law concerning Privacy Shield).
