Are digital signatures actually that secure? Isn’t it just as strong as your computer? (Aka can be really weak)

I am studying for my SEC+ exam, and prof messer’s videos, and he is going on and on about how secure digital signatures are, how they prove ‘it was you’ who signed it, and it can’t be disproven, cant be faked etc.

Yet, all someone has to do is get on my computer, log onto whatever browser and could be signing stuff all day, and obviously its not me. So in this case it is quite clear the things that were signed were not me in the slightest despite the ‘it cant be faked’.

Am I missing something?



That would fall into device and identity security. Device security such as biometric authentication before someone can access your device and application identity security such as MFA prompt to access the application that uses the identity to send the content as you. Like it’s said there is no 100% security but DID.
