Security Tip: Default Admin Credentials — The First Thing Attackers Try

Most website owners change their passwords. Far fewer change the username — and almost nobody changes the credentials that came with the software.

Every popular platform ships with a well-known default: admin as the username, a predictable password, sometimes no password at all on a fresh install. Routers, cameras, WordPress installs, staging sites, database panels — the defaults are published in the manual, which means they are published for attackers too. The first thing an automated bot tries on your login page is not a clever exploit. It is admin / admin, admin / password, and a short list of factory defaults. It costs the attacker nothing to try, and it works far more often than anyone admits.

The fix takes five minutes and closes the easiest door on your site. First, rename the default admin account — never run a site under a username called admin. Second, set a long, unique password and turn on two-factor authentication wherever it is offered. Third, hunt down the forgotten logins: the staging copy, the old test install, the database panel you set up once and never used again. Those are the accounts most likely to still be running defaults, and the ones nobody watches.

A strong password on a default username is a locked door with the key still under the mat. Run a free check of your site's exposure at https://vulnerabilitytools.com/ and make credential hygiene part of your routine, alongside updates, backups and scans.
