Handling multiple databases with different database user

[TheAdnan]

I have two tenants that use two different databases, and each database has its own dedicated user. How can I set the DB_USERNAME to be dynamic, like DB_DATABASE?

Probably you can extend Spatie\Multitenancy\Models\Tenant with your own implementation that will also include db_username field in this table.

Than you have to also extend SwitchTenantDatabaseTask to change also database user name. Remember to keep null in config/database.php in tenant configuration to all fields that are dynamic.
