Is there a way to find out what my router password is?

The default password is usually printed on the back of the device.
If you have ever changed the password, there should be a reset button, also on the back, that will reset the router to factory presets, password included.

Reset button is usually pushed with a large paperclip, straightened out.

Yeah, Hold the reset button in for 10–30 seconds. On most routers this will reset to factory defaults. You’ll have to set everything back up. It’s usually easiest to connect directly through ethernet and hit it’s internal webpage. The ip will be something like 192.168.1.1. then just set it back up. Download the manual for it for all the details.

You could try hypnosis to recall the password.

Wow. Thanks you guys.
