Lock And Pen.
A locked (closed) padlock with a fountain pen or nib positioned at various angles in front of it. Vendors implement the same design as their 🔒 Locked and the same or similar design as their 🖋️ Fountain Pen or ✒️ Black Nib.
May represent digital certificates in public-key technology. May also have similar applications as 🔒 Locked (privacy, security) and 🖋️ Fountain Pen or ✒️ Black Nib (writing, signing).
Apple’s design previously displayed a nib, Google’s a full pen.
This emoji does not display in page titles on Apple’s Safari web browser, presumably to prevent less reputable sites from pretending to be secure (encrypted using HTTPS).
Locked with Pen was approved as part of Unicode 6.0 in 2010 under the name “Lock with Ink Pen” and added to Emoji 1.0 in 2015.
