Passport-local-mongoose : Authenticate user right after registration
<p>I am trying to use <a href="https://www.npmjs.com/package/passport-local-mongoose" rel="nofollow">passport-local-mongoose</a> to authenticate a user after submitting a POST on the /register form.
I can't figure out why i always get "unauthorized" &amp; oddly no data is submitted on the database (it works if i remove "passport.authenticate('local') from app.post("/register") ) <br/></p>

<p>any ideas ?</p>
