If you protect your Tweets, you’ll receive a request when new people want to follow you, which you can approve or deny. Accounts that began following you before you protected your Tweets will still be able to view and interact with your protected Tweets unless you block them.
Public Tweets: (the default setting): Are visible to anyone, whether or not they have a Twitter account.
Protected Tweets: May only be visible to your Twitter followers.

Accessing your Privacy Settings
Whenever you share something on Twitter, you can choose who you’ll share with by changing your tweets privacy settings.
To do so:
Go to your Privacy and safety settings. ( You will be shown how to access this shortly)
In the Tweet privacy section, check the box next to Protect my Tweets.
Click the Done /Save button at the bottom of the page.
You’ll receive a request when new people want to follow you, which you can approve or deny.
Your Tweets, including permanent links to your Tweets, will only be visible to your followers.
Your followers will not be able to use the Retweet icon to Retweet or Quote Tweet your Tweets.
Protected Tweets will not appear in third-party search engines (like Google search).
Your protected Tweets will only be searchable on Twitter by you and your followers.
Replies you send to an account that isn’t following you will not be seen by that account (because only your followers will see your Tweets).
Navigate to your profile page. If you’re using the mobile app, locate and select the Gear icon. If you’re using a desktop web browser, select the Profile icon near the upper-right corner, then choose Settings.
You may be asked to choose the account you want to change(This is for people who have multiple accounts, go ahead and select the one you want to modify)
The settings will appear. From here, locate and enable the option to Protect my Tweets. This will allow you to approve who can see your posts.
