Hrm.. To some degree it depends which password or key you're logged in with. If your browser has your master password saved these might work. But if you have the say, the active key in there, these wouldn't necessarily be a fix.

But a couple things you can try...

• Try to get the saved password copied out of your browser memory. This link shows how to get it out of chrome: http://www.thewindowsclub.com/manage-view-saved-passwords-chrome

If using another browser, just Google how to get a saved password out of (insert browser name here).

• Again assuming you're logged in with your master password, you can go into (on steemit) wallet -> password and then generate a new one. You'll be prompted to put in your master password or owner key which hopefully is auto filled by your browser.

If that works you'll be given the new, generated password.

But again, this all depends on the browser having the right master/owner key.
