I started to use LastPass a few months ago and imported passwords from my browsers.

Apparently, Google Chrome and Opera (based on Chromium) still pop-up the option to store passwords in my browser and probably simultaneously trying to fill in forms automatically.

Recently a conflict occurred on a site while logging in. I think passwords were changed and there was a different password stored in the browser then in LastPass. The auto-fill was not working correctly and maybe both tried to auto-fill the form.

I guess it might make sense to disable browser password storage and browser auto-fill to avoid this conflict. I'd like to be sure about:

  1. What is exactly happening?
  2. What are the pros & cons of having both?
  3. What is recommended to do?

    Clear your browsers, deactivate saving passwords option on them, delete related profiles to the websites that cause you trouble and then create new ones on LastPass.

What's happening

Both the built-in and Lastpass password managers are trying to auto fill/auto login and probably the built-in password manager gets precedence over Lastpass.

Pros and cons
Your passwords are stored redundantly.

Multiple popups to save /override passwords/login when saving new login data.
More efforts in terms of manageability.


  • Turn off built-in password manager/lastpass (either via browser settings or use the option from Lastpass's settings.

Lastpass allows saving the cross browser& cross platform login info in cloud, so you can access it from any* device using your credentials. I suggest you use it.

*some device features are available only in premium and enterprise versions. Eg: mobile addons.

  • Kind of what I was thinking as well.

You definitely don't want to allow this to continue. However small the risk may be, there is some non-zero risk of every stored copy of your passwords being exposed. So there's just no reason to be in the situation that a successful attack on LastPass or Chrome stored passwords will expose your passwords.

BTW, if you've not set a Chrome sync passphrase, then your passwords synced to Chrome can be read by Google. I'm not saying that they do read them or even that they store them in clear-text. Just that they have all the keys for decryption.

  • What are you talking about? I have a Sync Phrase set up. That is not my concern. My concern is parallel use of both versus using only one, say LastPass.
