Passport-Local Mongoose - Change password?

I use Passport-Local Mongoose to encrypt the account's password. But I don't know how to change the password.

Can you give some document or example to do it? Thank you.

With async/await method, you can improve the code of @steampowered as below:

  

    const sanitizedUser = await User.findByUsername(userName);

    try {
      await sanitizedUser.setPassword(newPassword);
      await sanitizedUser.save();
      res.status(200).json({ message: 'Successful!' });
    } 
    catch (err) {
      res.status(422).send(err);
    }

In passport-local-mongoose you dont have to create any methods in schema, instead you can directly use changePassword command. Here is an example 

router.post('/changepassword', function(req, res) {

User.findOne({ _id: 'your id here' },(err, user) => {
  // Check if error connecting
  if (err) {
    res.json({ success: false, message: err }); // Return error
  } else {
    // Check if user was found in database
    if (!user) {
      res.json({ success: false, message: 'User not found' }); // Return error, user was not found in db
    } else {
      user.changePassword(req.body.oldpassword, req.body.newpassword, function(err) {
         if(err) {
                  if(err.name === 'IncorrectPasswordError'){
                       res.json({ success: false, message: 'Incorrect password' }); // Return error
                  }else {
                      res.json({ success: false, message: 'Something went wrong!! Please try again after sometimes.' });
                  }
        } else {
          res.json({ success: true, message: 'Your password has been changed successfully' });
         }
       })
    }
  }
});   });

If you want to change the password without using old password then use setPassword method. It is used for forgot password condition. Here is the code 

 user.setPassword(req.body.password, function(err,user){
if (err) {
    res.json({success: false, message: 'Password could not be saved. 
  Please try again!'})
} else { 
  res.json({success: true, message: 'Your new password has been saved 
successfully'})
             }
             });

As stated in the other answers, you need to get a new instance of the user object from the database, which is async so you need to either user await or use the callback/Promise function like this...

User.findOne({ username: req.user.username })
.then((u) => {
    u.setPassword(req.body.newPassword,(err, u) => {
        if (err) return next(err);
        u.save();
        res.status(200).json({ message: 'password change successful' });
    });

})

I think you can use changepassword method which was implemented in version 4.1.0

https://github.com/saintedlama/passport-local-mongoose/blob/master/CHANGELOG.md#410--2017-08-08

For implementation reference you can check the written tests at following location:

https://github.com/saintedlama/passport-local-mongoose/blob/807d9cf669f7a7c433eb0206c97574761c03b8e5/test/passport-local-mongoose.js#L217

No need to authenticate. Retrieve user from account using findByUsername() method, which was placed on the model by passport-local-mongoose, then run setPassword(), then user.save() in the callback.

userModel.findByUsername(email).then(function(sanitizedUser){
    if (sanitizedUser){
        sanitizedUser.setPassword(newPasswordString, function(){
            sanitizedUser.save();
            res.status(200).json({message: 'password reset successful'});
        });
    } else {
        res.status(500).json({message: 'This user does not exist'});
    }
},function(err){
    console.error(err);
})

I call the user sanitizedUser() because I have configured passport-local-mongoose to not return the password or salt fields using findByUsername() and the passport options in the model.

Good answer, but for ones who come from the MEAN stack (uses passport-local, not passport-local-mongoose):

//in app/models/user.js

/**
 * Virtuals
 */
UserSchema.virtual('password').set(function(password) {
    this._password = password;
    this.salt = this.makeSalt();
    this.hashed_password = this.encryptPassword(password);
}).get(function() {
    return this._password;
});

So this would change the pass:

user.password = '12345678';//and after this setter...
user.save(function(err){ //...save
    if(err)...
});

Looking at the source there is a function that is added to the schema called setPassword. I believe that after authenticating you can call it to change the password for the user.

schema.methods.setPassword = function (password, cb) {
    if (!password) {
        return cb(new BadRequestError(options.missingPasswordError));
    }

    var self = this;

    crypto.randomBytes(options.saltlen, function(err, buf) {
        if (err) {
            return cb(err);
        }

        var salt = buf.toString('hex');

        crypto.pbkdf2(password, salt, options.iterations, options.keylen, function(err, hashRaw) {
            if (err) {
                return cb(err);
            }

            self.set(options.hashField, new Buffer(hashRaw, 'binary').toString('hex'));
            self.set(options.saltField, salt);

            cb(null, self);
        });
    });
};
