Hi,
ok, now I have understood.
Easy Profile does not do this, but Joomla have a "Required Reset Password" feature.
You can import user with this option enabled, here an example of CSV
name;username;password_clear;email;requireReset
Reset;reset;reset;[email protected];1
You can create a column "requireReset" in your CSV, and the user need to change its password after first login.
"requireReset" is a Joomla core hidden field.
If you have already imported your users then you can enable "Required Reset Password" from backend with "Batch" button (see screenshot).
We do not provide documentation about this, because it is a part of Joomla and not Easy Profile.
