### Additional parameters
| Parameter | Description |
| ------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| id_token_hint | Valid `id_token` (of an existing session) used to identity the subject. **SHOULD** be provided when using prompt `none`. |
| login_hint | A valid logon name of a user. Will be used for username inputs or preselecting a user on `select_account` |
| max_age | Seconds since the last active successful authentication of the user |
| nonce | Random string value to associate the client session with the ID Token and for replay attacks mitigation. **MUST** be provided when using **implicit flow**. |
| Parameter | Description |
| ------------- |------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| id_token_hint | Valid `id_token` (of an existing session) used to identity the subject. **SHOULD** be provided when using prompt `none`. |
| login_hint | A valid logon name of a user. Will be used for username inputs or preselecting a user on `select_account`. Be sure to encode the hint correctly using url encoding (especially when using `+` or alike in the loginname) |
| max_age | Seconds since the last active successful authentication of the user |
| nonce | Random string value to associate the client session with the ID Token and for replay attacks mitigation. **MUST** be provided when using **implicit flow**. |
| prompt | If the Auth Server prompts the user for (re)authentication. <br />no prompt: the user will have to choose a session if more than one session exists<br />`none`: user must be authenticated without interaction, an error is returned otherwise <br />`login`: user must reauthenticate / provide a user name <br />`select_account`: user is prompted to select one of the existing sessions or create a new one <br />`create`: the registration form will be displayed to the user directly |
| state | Opaque value used to maintain state between the request and the callback. Used for Cross-Site Request Forgery (CSRF) mitigation as well, therefore highly **recommended**. |
| ui_locales | Spaces delimited list of preferred locales for the login UI, e.g. `de-CH de en`. If none is provided or matches the possible locales provided by the login UI, the `accept-language` header of the browser will be taken into account. |
