Bug: USER_PASSWORD_AUTH flow activates 'PASSWORD_VERIFIER' challenge

[Shpionus]

userPasswordAuthFlow by default returns verifyPasswordChallenge (ref).

But USER_PASSWORD_AUTH does not require providing DEVICE_KEY

Steps to reproduce:

1. Crate pool

aws --endpoint http://127.0.0.1:5000 cognito-idp create-user-pool \
        --pool-name $POOL_NAME \
        --query UserPool.Id --output text \
        --policies "PasswordPolicy={MinimumLength=6,RequireUppercase=true,RequireLowercase=true,RequireNumbers=true,RequireSymbols=true,TemporaryPasswordValidityDays=7}" \
        --username-attributes "email" \
        --account-recovery-setting 'RecoveryMechanisms=[{Priority=1,Name=verified_email}]'

2. Create client

aws --endpoint http://127.0.0.1:5000 cognito-idp create-user-pool-client \
        --user-pool-id $POOL_ID  \
        --client-name $CLIENT_NAME \
        --no-generate-secret \
        --explicit-auth-flows "ALLOW_USER_PASSWORD_AUTH" "ALLOW_REFRESH_TOKEN_AUTH" \
        --prevent-user-existence-errors ENABLED \
        --query UserPoolClient.ClientId --output text\

3. Sign up

aws --endpoint http://127.0.0.1:5000 cognito-idp sign-up \
        --client-id $CLIENT_ID \
        --username [email protected] \
        --password "1qazXSW@"  \
        --user-attributes Name="email",Value="[email protected]"

{
    "UserConfirmed": false,
    "UserSub": "7c82e5cc-99b6-468d-8c33-9bb0272bbbfe"
}

4. Sign in

aws --endpoint http://127.0.0.1:5000 cognito-idp initiate-auth \
        --auth-flow USER_PASSWORD_AUTH \
        --auth-parameters USERNAME="[email protected]",PASSWORD="1qazXSW@" \
        --client-id $CLIENT_ID \
        --debug
