Welcome to Justanswer.com, my name is Dustin.I'm sorry to hear about the issue you are having, I will do my best to help you resolve it.
To start with, I need to know the version of mac osx you have on your machine, you can check as follows.Click the apple sign at the top left of your screen, then click about this mac. And then where it says version, send that to me as a reply.
Also, do you use time machine?
Understood, then your Safari passwords wont be backed up there.
If you have an ipad or iphone, you may be able to recover some of the passwords from your icloud keychain as shown here
Now, you mentioned you had tried looking in your keychain for the passwords. Do you mean the keychain manager on your mac?
Im assuming you dont have an Iphone or ipad we can view some of the stored passwords from?
When you went to keychain access on your mac, did you search by website, or username? I know you mentioned the passwords in keychain were limited.. Browsing your keychain can be a bit daunting if you arent familiar with it.. How thorough were you?
If your mac is connected to your home network wirelessly, then the password ***** *****
Maybe a guide through the process will help. http://osxdaily.com/2010/12/10/forgot-wireless-password/
Other wise I could connect to your mac from here and help you find or change your wireless password.
Hello again, I never heard back from you after you viewed my reply. Did you still need help with this issue?
Please respond when you can so we can either work through this issue or mark it as resolved, thank you.
when you are in keychain access, that will show you all your saved passwords.
Launch “Keychain Access” located in /Applications/Utilities/ (Keychain Access can be easy to access from Spotlight with Command+Spacebar)
If you browse through keychain access, you should be able to locate most if not all, of your saved passwords.
However, depending on the browser you had your passwords saved through, they may not have saved to the keychain.
