It is now possible to sign documents without strong authentication. This means that the signing is done by using your finger on the touchscreen or by drawing your signature with your computer mouse.
In your company settings, you can specify whether you want strong authentication or light signature to be set as default. You can also define whether it is possible to choose which signature to use when creating an invitation or not.
Allowed signatures are defined in Settings -> Organization info -> Invitation settings -> Edit.
You can change allowed signature and default signature types in the following way:
Allowed signature types: With this option, you can define whether your company documents can be signed with strong authentication, light signature, or is it possible to sign with both types.
Default signature type: This option defines which setting is as default when the invitation is created.
