Passwords
The accounts-password
package contains a full system for password-based
authentication. In addition to the basic username and password-based
sign-in process, it also supports email-based sign-in including
address verification and password recovery emails.
The Meteor server stores passwords using the bcrypt algorithm. This helps protect against embarrassing password leaks if the server’s database is compromised.
To add password support to your application, run this command in your terminal:
meteor add accounts-password
In addition to configuring the
MAIL_URL
, it is critical that you set proper values (specifically thefrom
address) inAccounts.emailTemplates
to ensure proper delivery of e-mails!
You can construct your own user interface using the
functions below, or use the accounts-ui
package to
include a turn-key user interface for password-based sign-in.
Accounts.createUser(options, [callback])
Create a new user.
Arguments
- callback Function
-
Client only, optional callback. Called with no arguments on success, or with a single
Error
argument on failure.
Options
- username String
-
A unique name for this user.
- email String
-
The user's email address.
- password String
-
The user's password. This is not sent in plain text over the wire.
- profile Object
-
The user's profile, typically including the
name
field.
On the client, this function logs in as the newly created user on successful completion. On the server, it returns the newly created user id.
On the client, you must pass password
and at least one of username
or email
— enough information for the user to be able to log in again later. If there are existing users with a username or email only differing in case, createUser
will fail. The callback’s error.reason
will be 'Username already exists.'
or 'Email already exists.'
In the latter case, the user can then either login or reset their password.
On the server, you do not need to specify password
, but the user will not be able to log in until it has a password (eg, set with Accounts.setPassword
). To create an account without a password on the server and still let the user pick their own password, call createUser
with the email
option and then call Accounts.sendEnrollmentEmail
. This will send the user an email with a link to set their initial password.
By default the profile
option is added directly to the new user document. To
override this behavior, use Accounts.onCreateUser
.
This function is only used for creating users with passwords. The external service login flows do not use this function.
Instead of modifying documents in the Meteor.users
collection
directly, use these convenience functions which correctly check for case
insensitive duplicates before updates.
Accounts.createUserVerifyingEmail(options)
Creates an user and sends an email if options.email
is informed.
Then if the sendVerificationEmail
option from the Accounts
package is
enabled, you'll send a verification email if options.password
is informed,
otherwise you'll send an enrollment email.
Options
- username String
-
A unique name for this user.
- email String
-
The user's email address.
- password String
-
The user's password. This is not sent in plain text over the wire.
- profile Object
-
The user's profile, typically including the
name
field.
Accounts.setUsername(userId, newUsername)
Change a user's username. Use this instead of updating the database directly. The operation will fail if there is an existing user with a username only differing in case.
Arguments
- userId String
-
The ID of the user to update.
- newUsername String
-
A new username for the user.
Accounts.addEmail(userId, newEmail, [verified])
Add an email address for a user. Use this instead of directly updating the database. The operation will fail if there is a different user with an email only differing in case. If the specified user has an existing email only differing in case however, we replace it.
Arguments
- userId String
-
The ID of the user to update.
- newEmail String
-
A new email address for the user.
- verified Boolean
-
Optional - whether the new email address should be marked as verified. Defaults to false.
By default, an email address is added with { verified: false }
. Use
Accounts.sendVerificationEmail
to send an
email with a link the user can use to verify their email address.
Accounts.removeEmail(userId, email)
Remove an email address for a user. Use this instead of updating the database directly.
Arguments
- userId String
-
The ID of the user to update.
- email String
-
The email address to remove.
Accounts.verifyEmail(token, [callback])
Marks the user's email address as verified. Logs the user in afterwards if the user doesn't have 2FA enabled.
Arguments
- token String
-
The token retrieved from the verification URL.
- callback Function
-
Optional callback. Called with no arguments on success, or with a single
Error
argument on failure.
If the user trying to verify the email has 2FA enabled, this error will be thrown:
- “Email verified, but user not logged in because 2FA is enabled [2fa-enabled]”: No longer signing in the user automatically if the user has 2FA enabled.
This function accepts tokens passed into the callback registered with
Accounts.onEmailVerificationLink
.
Accounts.findUserByUsername(username, [options])
Finds the user with the specified username. First tries to match username case sensitively; if that fails, it tries case insensitively; but if more than one user matches the case insensitive search, it returns null.
Arguments
- username String
-
The username to look for
Options
- fields Mongo Field Specifier
-
Dictionary of fields to return or exclude.
Accounts.findUserByEmail(email, [options])
Finds the user with the specified email. First tries to match email case sensitively; if that fails, it tries case insensitively; but if more than one user matches the case insensitive search, it returns null.
Arguments
- email String
-
The email address to look for
Options
- fields Mongo Field Specifier
-
Dictionary of fields to return or exclude.
Use the below functions to initiate password changes or resets from the server or the client.
Accounts.changePassword(oldPassword, newPassword, [callback])
Change the current user's password. Must be logged in.
Arguments
- oldPassword String
-
The user's current password. This is not sent in plain text over the wire.

-
Optional callback. Called with no arguments on success, or with a single
Error
argument on failure.

Arguments
- callback Function
-
Optional callback. Called with no arguments on success, or with a single
Error
argument on failure.
Options
- email String
-
The email address to send a password reset link.
This triggers a call
to Accounts.sendResetPasswordEmail
on the server. When the user visits the link in this email, the callback
registered with Accounts.onResetPasswordLink
will be called.
If you are using the accounts-ui
package, this is handled
automatically. Otherwise, it is your responsibility to prompt the user for the
new password and call resetPassword
.
Accounts.resetPassword(token, newPassword, [callback])
Reset the password for a user using a token received in email. Logs the user in afterwards if the user doesn't have 2FA enabled.
Arguments

Error
argument on failure.

AccountsClient#onResetPasswordLink
and
Accounts.onEnrollmentLink
.
If the user trying to reset the password has 2FA enabled, this error will be thrown:

Enable 2FA for this package
You can add 2FA to your login flow by using the package accounts-2fa. You can find an example showing how this would look like here.
