Is Buttercup safe?

Clean risk

This extension helps fill and save website logins from your Buttercup password archive.

It works with the Buttercup desktop application to access your password archive and help you log in to online profiles and sites. When it detects a new login, it can prompt you to save the credentials to your archive. Archives can be hosted in locations you choose, including Dropbox, Google Drive, WebDAV connections, or local files.
