How do I find stored passwords in Windows 10?

Question

I've been looking everywhere for my saved passwords on my windows 10 PC, actually I also need to find them on my android pane, but my main PC with widows 10 is more important. My tablet, phone and PC seem to have a problem accepting my new passwords after I changed them, or preferably without having to change them yet again. I tried the advice given to other users with the same question, but when I do manage to find my way to credential manager and manage passwords, it demands ID verification with a username and password, which I can't even remember having set up in the first place. I could really use some help with this issue, before I end up in the nut house! I've tried amongst others, the way described below:

1. Press Win + R to open Run.
2. Type inetcpl.cpl, and then click OK.
3. Go to the Content tab.
4. Under AutoComplete, click on Settings.
5. Click on Manage Passwords. This will then open Credential Manager where you can view your saved passwords.
