Kullanıcının düz metin (plaintext) `password`'ünü asla saklamayın. Her zaman sonradan doğrulayabileceğiniz "güvenli bir hash" saklayın.

Eğer bilmiyorsanız, "password hash" nedir konusunu [güvenlik bölümlerinde](security/simple-oauth2.md#password-hashing) öğreneceksiniz.

Never store user's plaintext passwords. Always store a "secure hash" that you can then verify.

If you don't know, you will learn what a "password hash" is in the [security chapters](security/simple-oauth2.md#password-hashing).

## Multiple models { #multiple-models }

Here's a general idea of how the models could look like with their password fields and the places where they are used:
