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.
On the Main Website: Scroll to the very bottom of the page at https://lastpass.com/ and click on the globe icon, and select the preferred language.
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. + Make sure your browser language is set to the desired language (e.g. to set this in Chrome, follow the steps here). Then restart the browser.
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.
