Insecure Login Warning
From Lastpass 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 Preferences > Advanced > Enable or Disable the setting Warn before filling insecure forms > Save.
