}

• signupTokenExpires: Date object usually 24h ahead of signupTimestamp
• failedLoginAttempts: save failed login attempts during login process, default is 0
• derived_key: password hash generated by pbkdf2
• salt: salt generated by crypto.randomBytes()

adapter.save('john', 'john@email.com', 'secret', function(err, user) {
  if (err) console.log(err);
  console.log(user);
  // {
  //  _id: '8c7cd00c55a25ceb279a8e893d011b3e',

});

2. Find user

adapter.find(match, query, callback)

• match: String - one of the following: 'name', 'email' or 'signupToken'
• query: String - corresponds to match, i.e. 'john@email.com'

adapter.find('name', 'john', function(err, user) {
  if (err) console.log(err);
  console.log(user);
  // {
  //  _id: '8c7cd00c55a25ceb279a8e893d011b3e',
  //  _rev: '1-530a4cd8e67d51daf74e059899c39cd5',

  //  iterations: 10,
  //  name: 'john',
  //  email: 'john@email.com',

  // }
});

3. Update user

adapter.update(user, callback)

• user: Object - must have _id and _rev properties
• callback: Function - callback(err, user) - user is the updated user object

// get a user from db first
adapter.find('name', 'john', function(err, user) {
  if (err) console.log(err);

  // add some new properties to our existing user
  user.newKey = 'and some value';
  user.hasBeenUpdated = true;

  // save updated user to db
  adapter.update(user, function(err, user) {
    if (err) console.log(err);
    // ...
  });
});

4. Delete user

adapter.remove(name, callback)

• name: String
• callback: Function - callback(err, res) - res is true if everything went fine

adapter.remove('john', function(err, res) {
  if (err) console.log(err);
  console.log(res);

});
