What is the legal force of a graphic signature in a PDF (Facsimile)?

Question

Law in IT

There are many services on the Internet that offer to sign a document (PDF) with their help.
Most often this is an overlay of a graphic signature - a facsimile that can be left with a touchpad or mouse stroke, but alternatively they also offer to simply "print" their name using italic font.
what is the legal force of such a signature, if the signatory is not actually associated with any documents, and it is also impossible to identify a specific person from such a signature, and even more so if it is simply typed on the keyboard.
Any private keys in this case are not required, and many companies seem to accept such documents.
How does such a document signed by me differ from another signed not by me, or not on this service, but simply compiled from a pdf + signature image (even if mine).

Answer 1

No legal force. More precisely, no more than correspondence by e-mail or a scan of a document.
