What is the issue?
Basware Message is not recognizing your password anymore or you forgot the password to open Basware Message.
NOTE: For older versions and different Windows Operating Systems, KeyStore.jks can be found in one of the following paths: "C:\Program Files\First Businesspost\1stbp Message\"
"C:\Users\Public\First Businesspost\1stbp Message\" or
"C:\Documents and Settings\All Users\Application Data\Basware\Basware Message\".
If you chose to not add a new password and don't want the prompt to show everytime when opening the app, you can go to Message - Configuration - Options and check "Don't ask for Password".
