Identities
An identity is an authentication method associated with a user. Supabase Auth supports the following types of identity:
- Phone
- OAuth
- SAML
A user can have more than one identity. Anonymous users have no identity until they link an identity to their user.
The user identity object
The user identity object contains the following attributes:
| Attributes | Type | Description |
|---|---|---|
| id | string | The provider id returned by the provider. If the provider is an OAuth provider, the id refers to the user's account with the OAuth provider. If the provider is email or phone, the id is the user's id from the auth.users table. |
| user_id | string | The user's id that the identity is linked to. |
| identity_data | object | The identity metadata. For OAuth and SAML identities, this contains information about the user from the provider. |
| identity_id | string | The unique id of the identity. |
| provider | string | The provider name. |
| created_at | string | The timestamp that the identity was created. |
| last_sign_in_at | string | The timestamp that the identity was last used to sign in. |
| updated_at | string | The timestamp that the identity was last updated. |
