### Check the password { #check-the-password }

At this point we have the user data from our database, but we haven't checked the password.

Let's put that data in the Pydantic `UserInDB` model first.

You should never save plaintext passwords, so, we'll use the (fake) password hashing system.

	pp.SetContentType("image/jpeg")
	pp.SetUserMetadata("uuid", "14365123651274")
	pp.SetKeyStartsWith("user/user1/filename")
	pp.SetContentLengthRange(100, 999999) // not testable from this layer, condition is checked in the API handler.
	pp.SetSuccessStatusAction("201")
	pp.SetCondition("eq", "X-Amz-Credential", "KVGKMDUQ23TCZXTLTHLP/20160727/us-east-1/s3/aws4_request")
	pp.SetCondition("eq", "X-Amz-Algorithm", "AWS4-HMAC-SHA256")

They will be checked independently for each *path operation*.

## Check it { #check-it }

If you open the API docs, you can authenticate and specify which scopes you want to authorize.
