I can’t “speak” well. Sorry but I will try.

I have a Dell XPS, a VIZIO and Linksys Routers. The Linksys11212 Wi-Fi is fine for my XPS and VIZIO. I went to Verizon (because it is cracked screen) and checked “something”. When I got home, my phone MOTO Z3 doesn’t Wi-Fi.  I can’t remember my password (my stroke) even though my Linksys is fine. 

Is there any way that I could find the password?
