credential database

Hello !
i’m currently folowing a fundamentals training for dbt and i’m at the step where I have to “deploy dbt”

i’am not able to find the “analytics” connection under “connection”. I do have only “snowflake”
As I have only snowflake, I selected snowflake.

but below they are asking for the credential of the database :

I have this error message :

1 check failed:
2 dbt was unable to connect to the specified database.
3The database returned the following error:
4
5 >Database Error
6 250001 (08001): Failed to connect to DB: FV08260.europe-west2.gcp.snowflakecomputing.com:443. Incorrect username or password was specified.

8 Check your database credentials and try again. For more information, visit:

I have no idea where I can find this credential…
does anyone know ?

thanks for your help
