What's already configured out of the box
After the one-click deploy, the Umami container and a PostgreSQL database are up and running together, with the database schema created automatically on first start — you don't need to run migrations by hand. and should be confirmed in your control panel before going live.
First login
Open the Umami URL shown in your Leneex panel; the default login is username admin and password umami, unless your panel auto-generates a unique password during install — check the credentials section of your server dashboard first. Whichever applies, change the password immediately from Settings → Profile before adding any tracked websites — the default credentials are publicly documented and a known target for scanners.
Adding your first website
Once logged in, go to Settings → Websites → Add website, enter the domain you want to track, and Umami generates a tracking snippet (a short <script> tag) to paste into your site's <head>. The snippet is under 2KB and loads asynchronously, so it won't slow down page rendering. If your site sits behind an ad blocker-heavy audience, renaming the tracker script via the TRACKER_SCRIPT_NAME environment variable — — can reduce blocked requests.
