User Profile Structure

Auth0’s normalized user profile consists of a few different components:

Details: Core User Profile object, which contains basic info, such as name, email, and timestamp of the user’s latest login, in pre-defined attributes. This object may also contain info from a user’s source connection. Most of the user attributes are root attributes (attributes stored at the first, or root, level of the user object), and some of these are editable.
Metadata: Two sub-objects that operate as secondary storage to store additional user info in customizable attributes: user_metadata and app_metadata. To learn more, including when to use app_metadata and user_metadata, read Understand How Metadata Works in User Profiles.

User profile attributes

The following attributes are available on the user profile. Many are root attributes (attributes stored at the first, or root, level of the user object), and some may be updated, imported, and exported, as noted below. If there are user fields that should not be stored by Auth0 due to privacy reasons, you can add the attributes you do not want persisting in Auth0 databases to the DenyList. To learn more, read Add User Attributes to the Deny List. By default, user profile attributes provided by other than Auth0 (such as Google, Facebook, or X) are not directly editable because they are updated from the identity provider each time the user logs in. Fore more information on attributes from identity providers, read Configure Identity Provider Connection for User Profile Updates. To be able to edit the name, nickname, given_name, family_name, or picture root attributes on the normalized user profile, you must configure your connection sync with Auth0 so that user attributes will be updated from the identity provider only on user profile creation. These root attributes will then be available to be edited individually or by bulk imports

Name	Type	Description	Search?	Update?	Import?	Upsert during import?	Export?
`app_metadata`	object	Custom fields that store info about a user that influences the user’s access, such as support plan, security roles (if not using the Authorization Core feature set), or access control groups. To learn more, read Metadata Overview.	Y	Y	Y	Y	Y
`blocked`	boolean	Indicates whether the user has been blocked. Importing enables subscribers to ensure that users remain blocked when migrating to Auth0.	Y	Y	Y	N	Y
`blocked_for`	array (object)	IP addresses that have been blocked under suspicion of a bruteforce attack.	N	N	N	N	N
`created_at`	date time	Timestamp indicating when the user profile was first created.	Y	N	N	N	Y
`email`	text	(unique) The user’s email address.	Y	Y	Y	N	Y
`email_verified`	boolean	Indicates whether the user has verified their email address.	Y	Y	Y	Y	Y
`family_name`	text	The user’s family name.	Y	Y	Y	Y	Y
`given_name`	text	The user’s given name.	Y	Y	Y	Y	Y
`guardian_authenticators`	array (object)	Detailed information about the guardian backup authorization methods the user has set up, including SMS and Recovery Codes.	N	N	N	N	N
`identities`	array (object)	Contains info retrieved from the identity provider with which the user originally authenticates. Users may also link their profile to multiple identity providers; those identities will then also appear in this array. The contents of an individual identity provider object varies by provider, but it will typically include the following: `connection` (text): Name of the Auth0 connection used to authenticate the user. `isSocial` (boolean): Indicates whether the connection is a social one. `provider` (text): Name of the entity that is authenticating the user, such as Facebook, Google, SAML, or your own provider. `user_id` (text): User’s unique identifier for this connection/provider. `profileData` (object): User info associated with the connection. When profiles are linked, it is populated with the associated user info for secondary accounts. In some cases, it will also include an API Access Token to be used with the provider.	Y	N	N	N	Y
`last_ip`	text	IP address associated with the user’s last login.	Y	N	N	N	Y
`last_login`	date time	Timestamp indicating when the user last logged in. If a user is blocked and logs in, the blocked session updates `last_login`. If you are using this property from inside a Rule using the `user<` object, its value will be associated with the login that triggered the rule; this is because rules execute after login.	Y	N	N	N	Y
`last_password_reset`	date time	Timestamp indicating the last time the user’s password was reset/changed. At user creation, this field does not exist. This property is only available for Database connections.	N	N	N	N	Y
`logins_count`	integer	Number of times the user has logged in. If a user is blocked and logs in, the blocked session is counted in `logins_count`.	Y	N	N	N	Y
`multifactor`	array (string)	List of multi-factor providers with which the user is enrolled.	N	N	N	N	Y
`multifactor_last_modified`	date time	Date and time of the last update to a user’s multifactor authentication.	N	N	N	N	Y
`name`	text	The user’s full name.	Y	Y	Y	Y	Y
`nickname`	text	The user’s nickname.	Y	Y	Y	Y	Y
`phone_number`	text	The user’s phone number. Only valid for users with SMS connections.	Y	Y	N	N	Y
`phone_verified`	boolean	Indicates whether the user has been verified their phone number. Only valid for users with SMS connections.	Y	Y	N	N	Y
`picture`	text	URL pointing to the user’s profile picture.	N	Y	Y	Y	Y
`tenant`	text	Name of the tenant being used.	N	N	N	N	N
`updated_at`	date time	Timestamp indicating when the user’s profile was last updated/modified. Changes to `last_login` are considered updates, so most of the time, `updated_at` will match `last_login`.	Y	N	N	N	Y
`user_id`	text	(unique) The user’s identifier. Importing allows user records to be synchronized across multiple systems without using mapping tables.	Y	N	Y	N	Y
`user_metadata`	object	Custom fields that store info about a user that does not impact what they can or cannot access, such as work address, home address, or user preferences. To learn more, read Metadata Overview.	Y	Y	Y	Y	Y
`username`	text	(unique) The user’s username.	Y	Y	Y	N	Y

User profile validation

Auth0 accepts a specific validation schema for certain fields in the user profile. See the table below for a list of requirements when setting profile attribute values.

All characters are converted to lowercase when saved to the User Profile.This is true for all Auth0 database connections. When Auth0 DB is not the source of truth (for example, custom DB with import mode off) as well as other kinds of social enterprise connections where Auth0 is not the source of truth, the email is retained as-is and not converted to lower case.

Field	Type	Character Limit	Validation
`email`	email	The maximum length is 64 characters for the user/local part and 256 characters for the domain part.	JSON validation schema.
`username`	string	The default allowed length for usernames is between 1 and 15 characters. Up to a maximum length of 128 characters.	The username field accepts the following characters: Alphanumeric characters (without accent marks, automatically converted to lowercase); The at sign (@) character (but email addresses are not allowed); The caret (^) character; The dollar sign ($) character; The dot (.) character; The exclamation (!) character; The grave accent (`) character; The minus (-) character; The number sign (#) character; The plus (+) character; The single quote (’) character; The tilde (~) character; The underscore (_) character; No other characters/symbols are allowed, and Auth0 does not validate or sanitize custom database inputs.
`phone_number`	phone	Standardized Format Phone numbers need to be in E.164 format
`password`	string	The minimum password length you can set is 1 byte, while the maximum is 72 bytes.	Standard Characters: ASCII characters in the range of 33-126 are valid, including: A through Z uppercase characters, a through z lower case characters, 0 through 9 numeric characters, special characters allowed.
`name`	string	1-150 characters	All UTF-8 characters are supported
`nickname`	string	1-350 characters	All UTF-8 characters are supported
`family_name`	string	1-150 characters	All UTF-8 characters are supported
`given_name`	string	1-150 characters	All UTF-8 characters are supported

Three other fields are not technically part of the user profile, but may be of interest when importing users:

password_hash (text): Hashed password for the user’s connection. When users are created, Auth0 uses bcrypt to secure the password. Importing compatible hashed passwords allows users to retain their passwords, thereby providing a smoother experience. Compatible passwords should be hashed using bcrypt or and have 10 saltRounds. Note that you can provide this field only when the user is first imported; you cannot update it later.
custom_password_hash (object): Hashed password for the user’s connection when created using an alternate algorithm. Used in place of the password_hash field. During the bulk import process, you can update the custom_password_hash if the user did not login using the initially imported custom_password_hash.
