    What we are going to be doing for 0:08
    this project is moving the SMTP settings into environment variables. 0:10
    You'll need an app password, so go ahead and 0:14
    get that set up if you haven't already. 0:16
    Don't worry, I'll be here when you're done. 0:18
    If we are always using the same SMTP provider, 0:21
    we'd only need to switch out the username and password. 0:24
    But what if we have different providers for different environments? 0:27
    Let's switch out all of our SMTP setting starting with debug. 0:31
    Debug is for sure something that we want to change based on environment. 0:35
    In our dev environment, we want all the details we can get, but for 0:39
    prod we'll turn them completely off. 0:44
    Let's update our .ENV file first. 0:46
    SMTP_DEBUG=2. 0:56
    SMTP_HOST="smtp.gmail.com" 1:01
    SMTP_PORT, =587. 1:11
    SMTP_SECURE="tls". 1:19
    SMTP_AUTH=true. 1:26
    And we'll want our SMTP_USERNAME and PASSWORD. 1:34
    Make sure you also add SMTP_FROM. 1:40
    For Gmail this needs to be set as our same Gmail email address. 1:47
    Let's also switch out the MAILTO_EMAIL and NAME. 1:56
    Once again, saving the file. 2:22
    Now we can go back and switch out all the hard-coded information. 2:30
    Getenv. 2:38
    Whoops. 2:42
    Copy this. 2:44
    Oops, SMTP_. 2:47
    We'll copy all of that. 2:50
    And this will be DEBUG. 2:54
    HOST. 3:01
    PORT. 3:05
    SECURE. 3:10
    AUTH. 3:15
    The USERNAME, And PASSWORD. 3:23
    We'll also change SMTP_FROM. 3:38
    And our mailtos. 3:43
    MAILTO_EMAIL and, MAILTO_NAME. 3:49
    Let's give this a try in the browser again to make sure things still work. 3:56
    Looks good. 4:12
    Now that we've secured our credentials, we're ready to change the data source for 4:13
    the quotes. 4:17
