If you've lost track of your password for ExpandShare, you can recover it yourself right from any login page.
Open your ExpandShare App on your mobile device or navigate to the website at http://app.expandshare.com
On the Login Page there is a Forgot password link. You can get to it here: https://app.expandshare.com/account/password_reset/
Enter the same email address as your ExpandShare account. You can double check it by finding your original invite email.
You'll be emailed a link to follow to select a new password.
If you don't find the email, search your inbox for Subject = "ExpandShare Password Reset" or Sender = email@example.com, as the email may be in your Junk folder.
If you were invited to ExpandShare, but never set up your account by selecting a password, then resetting your password will have no affect and you will not receive an email. Contact your Company Admin or firstname.lastname@example.org to have your invitation resent.
If you have unsubscribed from ExpandShare emails, you won't receive the reset email. Contact email@example.com to be resubscribed to emails.
