Why am I seeing the message, "LastPass has detected a login form that is insecure" when I visit a site?

LastPass will display this warning message if your LastPass web browser extension Preferences are enabled to warn before autofilling on a form that is not secure. This means that the website you are visiting uses an insecure method to submit data (LastPass specifically looks for GET and mailto: methods on the page).

  • When prompted, you will have two options:
  • Click OK if you trust the website, which will allow LastPass to fill your stored login data.
  • Click Cancel if you do not trust the website and/or do not want LastPass to autofill. If desired, you can still manually fill your login data.
  • Additionally, you can enable or disable this setting in your Preferences by doing the following:

  • Click the LastPass icon in your web browser toolbar, then go to Account Options > Extension PreferencesAdvanced > Enable or Disable the setting Warn before filling insecure formsSave.
