What are the default username and password?

[sf0nt]

I like the project and want to try it.
I tried to find the default username and password but nothing.
I write a file named .env with the following two lines but nothing:

SECRET_AUTH_USERS=name1@example.com:Password1@ENV_KEY1,name2@example.com:Password2@ENV_KEY2 SECRET_SESSION_SECRET=some_long_random_string_to_keep_things_steady_and_secureasdfasdf

I have tried everything but I don't know how I have to configure it.

Please, could you have to help? :)

Thank you very much
