Regenerate password for external login


I’ve a external app with different database user, I would like to link to invoice plane installation, how can I generate the password for login to invoiceplane taking the user details from external app?

I see that invoiceplane use salt password mode and see in the database ‘ip_users’ there are a field named user_psalt, but what is the combination for generate the password?

Thank you.
