espero que o link a seguir ajude você a corrigir o problema
- Check your "Google Dashboard" (see link at top of Chrome Settings page) and verify that your synced passwords are really gone (in the "Chrome Sync" section you should see a line for "Passwords:". the number is probably very low (or maybe zero))
- Restore the sync data files mentioned above (restore to some other, temporary location than where it normally lives)
- Quit Chrome (and then wait a few seconds to make sure it's really dead)
- Copy the restored data files into place (see file path above for Mac or maybe someone will reply with Windows info)
- VERY IMPORTANT: Turn off WiFi and/or disconnect from the Internet (you need to make sure Chrome cannot talk to Google's servers for a little while)
- Start Chrome
- Insure that your previously lost passwords have come back to life (look in Settings -> Manage saved passwords) They may take a few seconds to appear.
- Once you've seen that all your passwords have returned, tell chrome to not sync passwords (Under "Settings -> Advanced sync settings..." uncheck "Passwords")
- Quit and restart Chrome again
- Insure all your passwords are still there
- Turn on Wifi and/or reconnect to the network (so chrome can talk to google again)
- Restart chrome again
- Re-enable password sync (back to "Settings -> Advanced sync settings..." check the box for "Passwords")
- Restart chrome one more time (why not? It don't hurt nothin')
- Wait about 60 seconds or so then check your "Google Dashboard" and verify that the number of stored passwords is now at a more acceptable number (mine went from 3 to 214 to prove that I'd fixed it)
