Hi @connectionreset,

Welcome to Auth0 Community!

If you have `Requires Username` enabled for a custom database connection, you will need to then add the the `username` property to the [Login](https://auth0.com/docs/authenticate/database-connections/custom-db/templates/login) and [Get User](https://auth0.com/docs/authenticate/database-connections/custom-db/templates/get-user) scripts.

> **[Custom Database Action Script Execution Best Practices](https://auth0.com/docs/authenticate/database-connections/custom-db/custom-database-connections-scripts/execution#create-action-scripts)**
>

You should see an error message “DB Login Custom script: username is required” if you have it missing from these scripts when `Requires Username` is enabled.

Hope this helps!

Thanks,  
Dave
