Is Password Lock for Messenger™ safe?

Low risk

Password Lock for Messenger™ stores the user's lock-screen password as an unsalted SHA-256 hash in local browser storage.

The extension lets users set a password to lock access to messenger.com. When a password is created, it is hashed using SHA-256 with no salt or key-stretching and stored in chrome.storage.local. Anyone with read access to the extension's local storage partition can recover the original password via rainbow tables or dictionary attack against the stored hash.
