Why am I seeing the message, "We've detected an insecure login form" when I visit a site?
LastPass will display this warning message if your LastPass 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).

Attention: Currently, there are two different extension menu experiences, so instructions may differ depending on your navigational experience. The "new experience" applies to version 4.104.0 and newer for the LastPass browser extension, whereas the "previous experience" refers to version 4.103.0 and earlier.
- When prompted, choose from the following 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.
- Click the active LastPass icon
in your web browser toolbar.
- Take the action that matches your navigational experience:
- New experience – Select the Account tab, then go to .
- Previous experience – Select Account Options OR < your username > at the bottom of the menu, then go to .
- Check or uncheck the box for the Warn before filling insecure forms setting.
