It’s easy enough to forget your passwords. Sometimes passwords are saved hidden on your computer like on-line site passwords hidden in your browser. Here is how to dig them out or clear them out.
Let’s start with my main browser, Opera.
Opera ver 52.0.2871.37 (latest time of writing)
Go into settings menu by clicking on Alt + P. Or click on Menu (top left hand corner) and in the drop down menu click on Settings.
Click on Privacy & security (left hand menu). Click on the Show all passwords button in the Passwords section.
Then you get a list of saved passwords. Move your mouse over one and a box appears called Show. Clicking on this will show you the password. There is a X in a circle if you want to delete it from the list.
If you click on Show, it will prompt you first for your Windows login password if you have one set up.
Chrome Version 65.0.3325.181 (latest time of writing)
Click on the three stacked dots in the top right hand corner and in the drop down menu click on Settings or type the following in the URL (web address bar) and hit enter: chrome://settings
On the settings page, scroll down to the bottom until you see the word Advanced. Click on it – Go down to the Passwords and forms section.
You can also click on Settings, right hand side, three white stacked lines, near the word Settings. Then click on Advanced in the menu that opens, Then Passwords and forms.
Click on Manage passwords.
You’ll see a list of saved passwords. On the side you’ll see three stacked dots clicking on that brings up a menu with two options Details and Remove.
Clicking on Details brings up yet another window showing you the details of that site. Clicking on the eye symbol after the password field will show you your password.
It will prompt you first for your Windows login password if you have one set up.
Firefox 59.0.2 (64-bit) (latest time of writing)
Click on the three stacked lines in the top right hand corner and then Options.
Once in Options click on Privacy & Security in left hand menu and then in the Forms & Passwords section click on Saved Logins…
Click on Show Passwords and answer Yes to confirm. Notice the Remove and Remove All buttons. Guess what they do.
SeaMonkey 2.49.2 (latest time of writing)
SeaMonkey, used to be called Mozilla Suite, I mainly use the email client built in. Seamonkey as a browser is very slow and clunky and the latest updates disabled all my extensions and I can no longer add them back because they are no longer compatible. Not a good marketing move Seamonkey. But the browser does need a complete overall.
Either in the browser or email client, Click on Tools, top menu, then Password Manager and then Manage Stored Passwords.
When the Data Manager opens you’ll see a list of all saved sites under the Domain section. Click on one and then click on the Show Passwords button. Confirm choice by clicking on Yes. High-light and click on the Remove button if you don't want it saved there.
Neither, Firefox or Seamonkey prompts for account password in my case. If you set up a masterpassword for either you might be prompted.
Internet Explorer 11 on Windows 7
To manage Internet Explorer passwords you are supposed to use the Credential Manager in the Control Panel. I just saved my Facebook password on iE to show what it’s like. But it doesn’t show up in the manager.
Microsoft Edge
I don't have Windows 10 so no Microsoft edge but a quick search online yields this info:
Click the menu button (three dots top right hand corner) , select SettingsView advanced settings button. Click Managed my saved passwords. Click on one of the logins to edit the username or password.
You could use third party software from a site like www.nirsoft.net/utils/index.html#password_utils
Using these programs on your own system to recover your own passwords is not illegal. Using them to try to hack someone else account is. Also some anti-virus programs automatically will mark theses as a virus so you might have to temporally disable your anti-virus to use them.
