Forgotten your Cisco, Linksys, D-Link, NetGear or 3Com router’s username and password? There are two methods to recover the password and access the router, method number 1 involves resetting the password to factory settings, whereas method number 2 uses the master key to access the router.

Method 1 – Restore Factory Settings

Default Router Password And Restore Factory Settings

As shown in the image above, insert the tip of a pen or a paper clip into the ‘reset’ hole, push the button for 5 seconds or more, make sure the power is on for the router. For confirmation of resetting the router to default settings, you should be able to see all of the router’s LED flashes or blinks, on certain models the router would restart itself.

When you’re done, access the router with the default username and password as stated in your user manual.

Method 2 – Master Key / Password

Every router comes with a master key or password, these set of password enables you to access the router without restoring or losing the settings.
