Default Router Usernames and Passwords
The credentials routers ship with, by brand. They work only if nobody has changed them — and if nobody has, that is a problem worth fixing today.
Factory sign-in details
Where the sticker on your own unit disagrees with this table, the sticker wins. Several manufacturers now ship a unique password per device rather than a shared default.

Why these are public in the first place
Manufacturers ship identical credentials across an entire product line so support staff can talk customers through setup without asking them to read a label. The trade-off is that the pairs above appear in manuals, on support sites, and on the sticker attached to the router itself. They are not secrets and were never intended to be.
What that means practically: anyone who can reach your network — a guest, a neighbour who got your Wi-Fi password once, malware running on a laptop in the house — can open the admin panel and change DNS settings, open ports, or lock you out of your own router.
When none of them work
The password has been changed. That might have been you, an installer, or your internet provider if they supplied the hardware. Provider-supplied routers often carry a unique password on the label rather than a shared default.
If the label is missing and nobody remembers, a factory reset is the only route in — and it erases your Wi-Fi configuration along the way.
Choosing a replacement
Length matters more than symbol soup. A passphrase of three or four unrelated words beats something like P@ssw0rd! on both security and your ability to remember it six months later. Do not reuse your Wi-Fi password: the two protect different things, and someone who has one should not automatically get the other.
