How do I change the default language?
There are a few places where you can change the language, each corresponding with a different part of LastPass.
Online Vault and Account Settings: Go to your LastPass Vault > Account Settings > General > Language
Local Vault and Extension Menu: Go to your LastPass Icon > Preferences > Advanced > Language. Restart the browser. (At the moment the following option has no effect as it is still in development)
On Windows, if you run the Windows installer you can also choose your language; to reset it, you can uninstall LastPass (Start Menu > LastPass Uninstall) and then re-run the installer: https://lastpass.com/download.php.
