Your login page is the first screen many people see of your site, and by default it is the same grey box as everyone else’s. Latchkey lets you design it — colours, background, card, fields, button, typography, logo — and see the result on the real page while you work.
The preview is the real page. The panel loads your actual wp-login.php in a frame and updates it as you drag a slider. There is no second rendering path that can drift from what visitors get, so what you approve is what ships.
It never touches how logging in works. Every form stays the form WordPress rendered, posting where WordPress told it to post. No custom sign-in handling, no password processing, no session code. That is why Latchkey keeps working next to your two-factor and security plugins instead of fighting them — and why it cannot lock you out.
There is no licence key, no trial and no setting that stops halfway. Every template, every colour, every control in this plugin works on every install.
prefers-reduced-motion, and offers its own switch for people who want animation off regardless.The meter is drawn by this plugin but scored by WordPress core, using the zxcvbn library that already ships with WordPress. The calculation happens entirely in the browser. This plugin reads the resulting rating, not the password: it watches the class name core writes and mirrors it onto a segmented bar. No password value is read, stored, logged or transmitted by Latchkey.
The meter appears where WordPress creates a password — the “set a new password” screen. It never appears on the sign-in form, where showing an assessment of an existing password would tell you nothing useful.
