ember-simple-auth: only validate the password without logging in

Is it possible to only check the password with ember-simple-auth? I want the user to re-enter their password if they want to delete their account. Can this password check be done without touching the store using ember-simple-auth?

If I use code similar to this:

let loginPromise =
    session.authenticate('authenticator:jwt', { identification, password })
return loginPromise.then(() => true).catch(() => false) // allow/deny to delete the account

then the session is invalidated if the password is wrong, so the user is signed out. I want, however, to only disable the "Delete Account" button if the password is wrong (without any other side effects like signing in).
