Hello Nicole ,
Can I encrypt different files with different passwords? – Sorry to say, AxCrypt 2.x does not support different password for different files feature due to some security reasons. Please refer our blog for more info: https://www.axcrypt.net/blog/use-of-different-passwords/ .
Can be the encryption of the files other then my login password? — No, AxCrypt 2.x use a single sign on model where the same password is used to sign in to our servers and to protect your files.
