As you are about to import 250 users, I'm sure you have the code/add-on for import. Now lets set the default password for all like "password". Here is the code that you can add into your csv import code.


Now after each user import, write a code to send that user an email. By which you can let that user know that his new password is : "password". He/she must reset their password upon next login and it is mandatory.

Also you can create a custom table which have 2 fields, uID & passChanged. Just insert the uID = "each user ID" and passChanged = 0 while importing through code. And if they change the password, update the passChanged = 1. Then edit the profile page, so if the user is from that csv & passChanged = 0, an alert will be shown in his profile.

Note: A bit custom work required. I've done the same for one site where I have to import almost 12K users along with its attributes.

Thanks. That sounds like too much work. :-) But I may have to resort to it if I can't find a simpler option.

I bought and used this one last week:

Works like a charm when you set up your CSV right. You can also import a password along with custom attributes etc.

I can import passwords, but not their existing passwords. And giving them all new passwords would mean I need to send those passwords via email, which is insecure.
