CiviCRM Community Forums (archive)

Your online membership renewal will have a contribution page. In Drupal you can then remove the make contributions permission for the anonymous user. This means users will need an account to log in.
When they are presented with the access denied page in Drupal you might want to customise that as well and point the user to registration.

Hi Shashikant,

Restricting access to the renewal page isn't the approach that I would take -- after all, we want the process of renewing to be as simple and streamlined as possible. 

Instead, I would head over to Administer > Manage > Find and Merge Duplicates to change the rules that Civi uses to detect duplicates.  Tweak the "Strict" rules -- these are the ones used to whether the renewing member already exists in your database. 

It's true that you'll get more duplicates this way than if you were to require login, but you'll also get more members renewing.  When you weigh the increased member renewal income against the moderate staff time for deduping, you'll probably find that it's a net gain for your end user organization.
