Configure token expiration time

The Ory Hydra config.yaml file located in the main Ory Hydra directory allows you to adjust:

  • Expiration time of the user login and consent flow
  • Expiration time for an access token
  • Expiration time for an ID token
  • Expiration time for auth codes

This configuration is instance-wide, which means that it applies to all registered clients.

If you need to set different token lifespans for specific clients, you can do that by calling the OAuth2ClientLifespans endpoint of the Ory Hydra Admin API. The client configuration takes precedence over the instance-wide configuration. Read this section to learn more.

Instance-wide configuration​

You can change the configuration on the instance-wide level by adjusting specific keys in the Ory Hydra configuration.

The ttl.login_consent_request key defines the expiration time of the user login and consent flow.

path/to/hydra/config.yaml
#....
  ## login_consent_request ##
  #
  # Defines the expiration time of the user login and consent flow.
  #
  # Default value: 1h
  #
  # Set this value using environment variables on
  # - Linux/macOS:
  #    export TTL_LOGIN_CONSENT_REQUEST=<value>
  # - Windows Command Line (CMD):
  #    > set TTL_LOGIN_CONSENT_REQUEST=<value>
  #
  login_consent_request: 1h
 #....

Access token expiration​

The ttl.access_token key defines the expiration time of access tokens.

path/to/hydra/config.yaml
#....
## access_token ##
#
# Defines how long access tokens are valid.
#
# Default value: 1h
#
# Set this value using environment variables on
# - Linux/macOS:
#    export TTL_ACCESS_TOKEN=<value>
# - Windows Command Line (CMD):
#    > set TTL_ACCESS_TOKEN=<value>
#
access_token:
  1h
  #....

Refresh token expiration​

The ttl.refresh_token key defines the expiration time of refresh tokens.

tip

When set to -1, refresh tokens never expire.

path/to/hydra/config.yaml
#....
## refresh_token ##
#
# Defines how long refresh tokens are valid. Set to -1 for refresh tokens to never expire.
#
# Default value: 720h
#
# Set this value using environment variables on
# - Linux/macOS:
#    export TTL_REFRESH_TOKEN=<value>
# - Windows Command Line (CMD):
#    > set TTL_REFRESH_TOKEN=<value>
#
refresh_token:
  "-1"
  #....

ID token expiration​

The ttl.id_token key defines the expiration time of ID tokens.

path/to/hydra/config.yaml
#....
## id_token ##
#
# Defines how long id tokens are valid.
#
# Default value: 1h
#
# Set this value using environment variables on
# - Linux/macOS:
#    export TTL_ID_TOKEN=<value>
# - Windows Command Line (CMD):
#    > set TTL_ID_TOKEN=<value>
#
id_token:
  1h
  #....

Auth code expiration​

The ttl.auth_code defines the expiration time of auth codes.

path/to/hydra/config.yaml
#....
## auth_code ##
#
# Defines how long auth codes are valid.
#
# Default value: 10m
#
# Set this value using environment variables on
# - Linux/macOS:
#    export TTL_AUTH_CODE=<value>
# - Windows Command Line (CMD):
#    > set TTL_AUTH_CODE=<value>
#
auth_code:
  1h
  #....

Lifespan configuration for specific clients​

To adjust the configuration for a specific client, call the OAuth2ClientLifespans endpoint of the Hydra admin API. This endpoint allows to configure every combination of client, grant type, and token type.

tip

The configuration applied to a specific client using this endpoint precedes the instance-wide configuration set in the Hydra configuration file.

For example, to update the configuration of a client registered in a Hydra instance that runs locally, send this request:

$ curl -H "Content-Type: application/json" \
  -X PUT https://localhost:4445/clients/db779000-01f3-4c12-bf70-ff85933d485e/lifespans --data '{
