{
   "TokenOptions": {
      "SecurityKey": "<random-security-key>"
   },
   "PasswordOptions": {
      "SaltSize": 16,
      "KeySize": 32,
      "Iterations": 10000

   "EmailOptions": {
      "UserName": "<your-email-client-username>",
      "Port": "<your-email-client-port>",
      "Password": "<your-email-client-password>"
   },
   "DatabaseConnectionString": "<your-database-connection-string>"
}
cd backend/Api
dotnet user-secrets init
# For Windows users
type .\secrets.json | dotnet user-secrets set

# For mac/linux users
cat ./secrets.json | dotnet user-secrets set

Create the database

cd backend/Infrastructure
## If you want to use your own migration
dotnet ef migrations add "<your-migration-name>" -s ../Api

dotnet ef database update -s ../Api
