Authentication problem in Kyocera M3655IDN

[mizunora]

So I have a big problem, I need the Scanners sent via Email to not authenticate with the user's information, the problem is that the option to authenticate with the printer does not exist on this Model M3655IDN, I am sending the photo of a model that has the option and the other that does not.
Does anyone know of any possibility of solving this problem?

I believe if it doesn't have the setting, it will use the SMTP account that the MFP is set up with. It will show that is the account it is coming from.
