This shouldn't scare you away, however. Alexa-enabled devices are great to have in your home and, with a little tweaking, can prove to be very good companions. I’ve hand-picked some of the most useful and unique Alexa skills from the thousands that are out there. Many of these skills will not be enabled by default, so you may need to follow the proper activation steps before using each one for the first time. 
The Capital One skill allows you to check your credit card balance or make a payment when one is due. This is secure: The skill performs security checks and requires you sign in using your username and password. Then, when you open the skill, you must provide a four-digit code to confirm your identity. Just be wary of who is around when using the skill -- anyone who overhears you say your personal key can access your banking or credit card info just by asking Alexa.
You can create a flash briefing skill if you own, or have the right to distribute, original text or audio content that updates frequently. You should understand web technologies and have the ability to configure HTTPS, RSS and/or JSON content. The voice interactions for a flash briefing skill are defined by Amazon, but you must be able edit the format of your content so that the flash briefing Skill API can understand it.
For tracking your food, you can use the Track by Nutritionix skill, which lets you record your food intake using your voice, or ask for caloric values of foods. (Alexa does the latter by default.) Say things like, "Alexa, tell Food Tracker to log a cup of almond milk" or "Alexa, ask Food Tracker how many calories are in two eggs and three slices of bacon."

The next step in our Alexa flash briefing tutorial is to set up an Alexa skill for delivering the briefing. First, visit the Amazon Developer Console to create a new skill. Begin by giving it a name, then click “next.” You’ll be offered a selection of Alexa skill models to choose from. Select “flash briefing” from the list, then you’ll be met with a series of Alexa flash briefing options.
How does Alexa work? Once you buy an Amazon Alexa device — Amazon Tap or an Echo Dot — the device connects through WiFi or Bluetooth to the internet and then to other devices. With the most common devices, the Amazon Echo and Echo Dot, people merely say "Alexa," which wakes up the device, and then ask for what they want. Alexa Skills radically expands the bots repertoire, allowing users to perform more actions with voice-activated control through Alexa.
