Snapchat has approved or disapproved several plugins and applications. The use of unapproved plugins or apps could endanger your account. Unauthorized third-party apps utilize your username and password from your Snapchat account to access Snapchat services rather than using a secure connection like apps connected with Snap Kit do. An add-on that adds new features to the Snapchat app that aren't already present is called a plugin or tweak. If you use them or have them installed on your device, your Snapchat account may be locked because you might experience difficulties checking in.
