WordPress Hardening Checklist After Installation
This checklist is for website owners and operators who have just installed WordPress and want to reduce the most common security risks before publishing serious content or receiving traffic.
Why this matters
WordPress is flexible, but that flexibility also creates risk. Weak admin accounts, unused plugins, outdated themes, wrong file permissions and missing backups can turn a small website into an easy target.
Checklist
- Change the default admin username if it exists.
- Use a strong password for every administrator account.
- Verify that the site administration email belongs to you.
- Remove unknown users and unused administrator accounts.
- Update WordPress core, themes and plugins.
- Delete unused themes and plugins.
- Never use nulled themes or nulled plugins.
- Disable file editing inside the WordPress dashboard.
- Check file and folder permissions.
- Limit login attempts or add login protection.
- Set up backup before installing more plugins.
- Monitor users, plugins and suspicious file changes.
Important note
Hardening is not a one-time task. It is an operating habit. You need to review users, plugins, backups and logs regularly.
Final check
Your WordPress site is safer when admin access is controlled, unused code is removed, file editing is disabled, backups exist and you know how to detect suspicious changes.
