Tidy Draft Share features
One job, done properly: letting someone read an unpublished post without giving them access to your WordPress site.
Share without a login
Send an unpublished post to anyone with one secure link. No WordPress account, no password to hand out.
Expiring preview links
Every link carries an expiry you choose, and can be revoked the moment a review ends.
Client review workflow
Send a queue of drafts for approval, and close access when the engagement is over.
Free on WordPress.org
Install it, open a draft, click Share. There is nothing else to configure.
