[Koha] How to enable patron login in OPAC

We have a big database of over 20 thousand+ patrons. Now, we want to activate patron accounts so they can log-in and manage their own accounts. When we created each patron's account, a password was generated. What is this password and how can we update it for all patrons so they can all log-in with one password and then change it later on their own? Or if there is another way around this, I will really appreciate any new ideas. Thanks all in advance. -- View this message in context: http://koha.1045719.n5.nabble.com/How-to-enable-patron-login-in-OPAC-tp57847... Sent from the Koha-general mailing list archive at Nabble.com.
