main problem:
- we have lot's of domains
- we need to make sso and remember it in any subdomain if exists
- we have different auth ways
- auth service with different auth ways
- basic auth guard
- JWT keys used by default
- SDK for easy access which contains middleware and user model (by contract)
- rate limitter for sms (mock + smsaero drivers)
- reset password included (mock + mailgun drivers)
- extendable
- independent
- DB agnostic
- postman collection included
