# atoti.BasicAuthenticationConfig

### *final class* atoti.BasicAuthenticationConfig

The [basic authentication](https://en.wikipedia.org/wiki/Basic_access_authentication) config.

It is the quickest way to set up security since it only requires defining [`credentials`](./atoti.security.basic_authentication_security.BasicAuthenticationSecurity.credentials#atoti.security.basic_authentication_security.BasicAuthenticationSecurity.credentials) and [`individual_roles`](./atoti.security.Security.individual_roles#atoti.security.Security.individual_roles).
