Applications must not be given passwords. Consider that there are hundreds of applications/api/reports in a company, managed by hundreds of developers in different departments. Passwords would be leaked all over the place (verbose logging, debugging to investigate issues, etc...). That's totally compromising employees/users, as passwords are rarely changed and reused for personal accounts.
