[Passport](http://passportjs.org/) strategy for authenticating with a username
and password.
This module lets you authenticate using a username and password in your Node.js
applications. By plugging into Passport, local authentication can be easily and
unobtrusively integrated into any application or framework that supports
[Connect](http://www.senchalabs.org/connect/)-style middleware, including
[Express](http://expressjs.com/).
## Install
$ npm install passport-local
## Usage
#### Configure Strategy
The local authentication strategy authenticates users using a username and
password. The strategy requires a `verify` callback, which accepts these
credentials and calls `done` providing a user.
passport.use(new LocalStrategy(
function(username, password, done) {
User.findOne({ username: username }, function (err, user) {
if (err) { return done(err); }
if (!user) { return done(null, false); }
if (!user.verifyPassword(password)) { return done(null, false); }
return done(null, user);
});
}
));
#### Authenticate Requests
Use `passport.authenticate()`, specifying the `'local'` strategy, to
authenticate requests.
For example, as route middleware in an [Express](http://expressjs.com/)
application:
app.post('/login',
passport.authenticate('local', { failureRedirect: '/login' }),
function(req, res) {
res.redirect('/');
});
