Currently, staff can reset a patron's password in Koha. However, it would be nice to have Koha send an email with this password/patron details (as it does when registering a new patron) to the patron instead of having the staff write down and/or tell the patron the password. Due to security it would be nice if this was done without staff interaction with the actual password.
Koha can no longer send patron passwords by email. But we can now trigger the password reset email and the welcome email from staff side. I am marking this as WONTFIX.
