How to reset forgotten username and password on router
Computer Hope does not assist users in bypassing network security measures. However, if you've forgotten the username or password for a router on which you have authorized access, the following sections should be of assistance.
Default username and password
Before performing a hard reset on the router, you may want to try the default username and password. While not the same for all routers, it may grant you access.
Username: admin or administrator
Password: <Blank>, admin, or password
Tip: A comprehensive listing of default router username and password combinations is available at routerpasswords.com.
Resetting your router
If the default username and password are not working, it's likely that they've been changed at some point in the past by you or your network administrator. Most routers have a small pinhole button on the back or bottom (shown in the picture). Pressing and holding this button for 10-15 seconds hard resets the router. This action restores all default settings; including the username and password.
