This morning, two-factor authentication plugin Clef, also known as GetClef, announced that they are shutting down. They currently have more than 1 million active WordPress websites using their two-factor authentication plugin.
“Starting next week, we will be winding down our business and sunsetting the Clef product. Our team will be joining another company, which we’ll have more news about in the next few weeks.
The Clef product will continue operating for three months, starting today, with a final shutdown date of June 6, 2017. Everything will remain fully functional and maintained until that date, at which point the mobile apps will cease functioning and be removed from the Google Play and Apple App stores.
If you are a current Clef user, we recommend that you begin transitioning away from Clef as a login method as soon as possible. We’ve written a guide for both API and WordPress user with instructions on making that transition here.”
At this point, we don’t have any more detail on who Clef is joining and under what circumstances.
