You cannot set it in the env file. But sure you can in the `app/config/database.php`. — Sachin Bahukhandi, Nov 09 '22 at 04:50
You can create constants in config file for dynamic username and password — Leena Patel, Nov 09 '22 at 04:50

You can set dynamically set username and password(from database) in laravel (.env file).

$data = array('MAIL_USERNAME' => "set user name",'MAIL_PASSWORD' => "set password");

 if (count($data) > 0) {

            // Read .env-file
            $env = file_get_contents(base_path() . '/.env');

            // Split string on every " " and write into array
            $env = preg_split('/\s+/', $env);;

            // Loop through given data
            foreach ((array) $data as $key => $value) {

                // Loop through .env-data
                foreach ($env as $env_key => $env_value) {

                    // Turn the value into an array and stop after the first split
                    // So it's not possible to split e.g. the App-Key by accident
                    $entry = explode("=", $env_value, 2);

                    // Check, if new key fits the actual .env-key
                    if ($entry[0] == $key) {
                        // If yes, overwrite it with the new one
                        $env[$env_key] = $key . "=" . $value;
                    } else {
                        // If not, keep the old one
                        $env[$env_key] = $env_value;
                    }
                }
            }

            // Turn the array back to an String
            $env = implode("\n", $env);

            // And overwrite the .env with the new data
            file_put_contents(base_path() . '/.env', $env);

        \Artisan::call('config:cache');
        \Artisan::call('cache:clear');
        \Artisan::call('config:clear');
        \Artisan::call('optimize:clear');
        \Artisan::call('route:clear');

        }
