A small utility module which allows administrators to send one-time login links to selected users, and also generates a CSV of one-time login URLs for each user.
Once enabled, this module adds an update option "Send one-time login link to the selected users" to the form at Administration >> People, and also provides a one-time login links tab which prompts you to download a CSV file with the following columns:
[ user ID | user name | user e-mail address | one-time login URL | expiration date (if any) of the one-time login URL ]
One-time login URLs have an expiration date only if the user has previously logged in to the account.
Login one time can also generate one-time login URLs, but uses its own URLs which behave differently than Drupal core one-time login URLs.
